BREAKING CHANGES: API Simplification (Phase 2)
Removed Deprecated Function Exports
Version 0.6.0 removes 8 deprecated functions from the public API. These functions are now internal-only. Since we are pre-1.0.0, this is an acceptable breaking change.
What Changed
- Removed from NAMESPACE: 8 deprecated functions no longer exported:
-
Still callable internally: Functions remain in the package for
get_dataset()to use - NAMESPACE reduction: Exports reduced from 23 to 15 functions
Impact
- Users must migrate: These functions can no longer be called directly
-
get_dataset() is the only supported API: All data access must go through
get_dataset() - Cleaner public interface: Package exports only essential user-facing functions
Migration
These functions were deprecated in v0.4.0 (18+ months ago). Users must now use get_dataset():
# Old way (NO LONGER WORKS):
data <- get_secovi()
data <- get_bcb_series(table = "price")
data <- get_abecip_indicators(table = "sbpe")
# New way (REQUIRED):
data <- get_dataset("secovi")
data <- get_dataset("bcb_series", "price")
data <- get_dataset("abecip", "sbpe")Rationale
-
Simpler API: One function (
get_dataset()) instead of 15+ - Reduced maintenance: Fewer exported functions to document and test
- Pre-1.0.0 flexibility: Breaking changes acceptable before stable release
- 18-month deprecation period: Functions were deprecated since v0.4.0
Code Clarity Improvements
Renamed Confusing “Legacy” Terminology
-
Renamed:
get_from_legacy_function()→get_from_internal_function() - Rationale: These functions call internal worker functions, not “legacy” code
- Impact: Internal only - no user-facing changes
Files changed: R/get-dataset.R
CBIC Code Simplification and Table Availability
Code Reduction (~223 lines, 11% smaller)
- Removed: 100+ lines of commented-out old implementation code
-
Removed: 4 unused helper functions (124 lines total):
-
suppress_external_warnings()- Never called -
explore_cbic_structure()- Only in examples -
get_cbic_files()- Only in examples -
get_cbic_materials()- Only in examples
-
-
Removed: Unnecessary metadata attributes from
get_cbic_steel()andget_cbic_pim():attr(result, "source")attr(result, "download_time")attr(result, "download_info")- Associated tryCatch blocks and cli_user messages (~69 lines)
Table Availability Fixed
-
Unblocked:
steel_pricesandpimtables now accessible -
Blocked: Only
steel_productionremains blocked (has data quality issues) - Updated: Error messages now accurately reflect v0.6.0 status
-
Available tables:
- Cement: cement_monthly_consumption, cement_annual_consumption, cement_production_exports, cement_monthly_production, cement_cub_prices
- Steel: steel_prices
- PIM: pim, pim_production_index
BREAKING CHANGES: Documentation Simplification (Phase 1)
Removed Examples from Deprecated Functions
Version 0.6.0 removes usage examples from deprecated legacy functions to simplify the codebase. Since we are pre-1.0.0, this is an acceptable breaking change.
What Changed
-
Removed: All
@examplesblocks from 8 deprecated functions: -
Removed: Verbose
@sectionblocks (Progress Reporting, Error Handling) -
Simplified:
@detailssections to 1-3 essential lines -
Enhanced:
@section Deprecationblocks with code migration examples
Impact
- ~260-290 lines of documentation removed
- Documentation now focuses on migration guidance rather than usage examples
- All functions still exported and callable (no functionality changes)
- Help pages now emphasize using
get_dataset()instead
Migration
These functions were deprecated in v0.4.0. Users should migrate to the modern API:
# Old way (still works, but no longer documented with examples):
data <- get_secovi()
# New way (recommended):
data <- get_dataset("secovi")Full migration examples are available in each function’s @section Deprecation block.
Rationale
- Pre-1.0.0: Breaking changes are acceptable before stable release
- Codebase simplification: Reduces maintenance burden and package size
-
Focus on modern API: Encourages users to adopt
get_dataset()interface - Clear migration path: Enhanced deprecation warnings guide users to new API
realestatebr 0.5.1
Bug Fixes
SECOVI Default Table Fix
Fixed SECOVI dataset to return all categories by default instead of only “condo”
Problem:
get_dataset("secovi")was only returning the “condo” category (1,939 rows) instead of all categories (9,398 rows). This caused test failures for launch/rent/sale tables.Root Cause: When no table parameter was specified, the code defaulted to the first category alphabetically (“condo”), rather than fetching all categories.
-
Solution:
- Added
default_tableconfiguration support indatasets.yaml - Updated
validate_and_resolve_table()to check fordefault_tablesetting - Set SECOVI’s
default_table: "all"in registry - Regenerated cache with all 4 categories
- Added
-
Impact:
- Cache size: 12KB → 55KB (includes all categories)
- Data completeness: 1,939 → 9,398 rows
- Categories: condo (1,939), launch (780), rent (2,779), sale (3,900)
# Now returns all categories by default
get_dataset("secovi") # → 9,398 rows, 4 categories ✅
# Specific tables still work correctly
get_dataset("secovi", "launch") # → 780 rows
get_dataset("secovi", "rent") # → 2,779 rows
get_dataset("secovi", "sale") # → 3,900 rowsTest Infrastructure Improvements
- Updated test suite to use
devtools::load_all()instead oflibrary()to ensure testing of development version - Added comprehensive pre-release test suite (
tests/comprehensive_check_v0.5.qmd) - Added test result documentation (
tests/TEST_RESULTS_SUMMARY.md,tests/QUICK_SUMMARY.md)
realestatebr 0.5.0
BREAKING CHANGES: User-Level Caching Architecture
Major Architectural Change
Version 0.5.0 introduces user-level caching, removing bundled datasets from the package to comply with CRAN’s 5MB size limit. This is a BREAKING CHANGE that affects how datasets are accessed.
What Changed
-
Removed: All cached datasets from
inst/cached_data/(previously ~25MB) -
Added: User-level cache directory at
~/.local/share/realestatebr/(Linux/Mac) or%LOCALAPPDATA%/realestatebr/Cache/(Windows) - Added: GitHub Releases integration for pre-processed datasets
-
Changed:
source="cache"now refers to user cache, not package cache -
Changed:
source="github"now downloads from GitHub releases, not package files
New Cache Behavior
# First use: downloads from GitHub releases to user cache
data <- get_dataset("abecip") # Downloads once
# Subsequent uses: loads from user cache (instant, offline)
data <- get_dataset("abecip") # Loads from ~/.local/share/realestatebr/
# Force fresh download from original source
data <- get_dataset("abecip", source = "fresh") # Downloads and caches
# Explicit source selection
data <- get_dataset("abecip", source = "cache") # User cache only
data <- get_dataset("abecip", source = "github") # GitHub releases onlyAuto Fallback Strategy (source = “auto”, default)
-
User Cache: Check
~/.local/share/realestatebr/(instant, offline) -
GitHub Releases: Download pre-processed data (requires
piggybackpackage) - Fresh Download: Download from original source (saves to user cache)
New Dependencies
-
Added:
rappdirs(Imports) - Cross-platform user cache directory support -
Added:
piggyback(Suggests) - GitHub releases download support
New Functions
-
get_user_cache_dir(): Get path to user cache directory -
list_cached_files(): List all cached datasets -
clear_user_cache(): Remove cached datasets -
is_cached(): Check if dataset is in cache -
list_github_assets(): List available datasets on GitHub releases -
download_from_github_release(): Download specific dataset from releases -
update_cache_from_github(): Update cached datasets from GitHub -
is_cache_up_to_date(): Compare local vs GitHub cache timestamps
Migration Guide
For Users
# Install updated package
install.packages("realestatebr") # or devtools::install_github()
# Install piggyback for GitHub downloads (recommended)
install.packages("piggyback")
# First use after update: will download datasets to user cache
data <- get_dataset("abecip")
# Check cache location
get_user_cache_dir()
# Manage cache
list_cached_files() # See what's cached
clear_user_cache("abecip") # Clear specific dataset
clear_user_cache() # Clear all (with confirmation)For Package Developers
- Cached data files now excluded from package build via
.Rbuildignore - Package size reduced from ~25MB to <5MB (CRAN compliant)
-
inst/cached_data/kept for development/CI but excluded from distribution - GitHub Actions workflow publishes cache to releases via
data-raw/publish-cache.R
Benefits
- ✅ CRAN Compliant: Package size now <5MB (was 25MB)
- ✅ Faster Installation: Package downloads are much smaller
- ✅ Offline Usage: Once cached, datasets work offline
- ✅ User Control: Users manage their own cache
- ✅ Weekly Updates: GitHub releases updated automatically by CI
- ✅ No Breaking APIs:
get_dataset()interface unchanged
Deprecations
-
import_cached(): Still works but now loads from user cache (previously frominst/) - Old

realestatebr 0.4.0
Major Breaking Changes - API Consolidation
🎯 Unified Data Interface
This release implements a major breaking change that consolidates 15+ individual get_*() functions into a single, unified get_dataset() interface. This dramatically simplifies the package API while maintaining full functionality.
BREAKING CHANGE: All individual get_*() functions have been removed: - get_abecip_indicators(), get_abrainc_indicators(), get_rppi(), get_bcb_realestate(), etc. - Migration: Use get_dataset("dataset_name") instead
🔧 RPPI Code Simplification (Internal)
Major refactoring of RPPI functions for better maintainability: - 67% code reduction: 1579 lines → 519 lines (1060 lines removed) - Bug fix: FipeZap national index now correctly standardized to name_muni == "Brazil" - Shared helpers: Created rppi-helpers.R with common functions to eliminate duplication - Removed overhead: Eliminated unused stack parameter, cli_debug calls, and metadata attributes - Simplified documentation: Removed verbose sections (Progress Reporting, Error Handling, Examples) from internal functions - All functions now @keywords internal: Only get_dataset() is user-facing
Benefits: - Easier to maintain and debug - Faster execution (less overhead) - Consistent error handling across all indices - Bug fixes apply to all functions automatically
📊 CBIC Dataset - Partial Release (Cement Only)
Note: In v0.4.0, the CBIC dataset is limited to cement tables only (validated data). Steel and PIM tables will be added in v0.4.1.
Available in v0.4.0: - ✅ cement_monthly_consumption - Monthly cement consumption by state - ✅ cement_annual_consumption - Annual cement consumption by region - ✅ cement_production_exports - Production, consumption, and export data - ✅ cement_monthly_production - Monthly cement production by state - ✅ cement_cub_prices - CUB cement prices by state
Coming in v0.4.1: - ⏳ Steel prices and production data - ⏳ PIM industrial production indices
