Almost a complete rewrite of the package.
R >= 4.1.0 is now required.
create_CRU_stack() and create_CRU_df() functions have been removed.
get_CRU_stack() and get_CRU_df() functions have been removed.
New functions read_cru_rast() to align with {terra} naming and read_cru_dt() to align with {data.table} naming have been added to either download or load data from local files using a single unified function.
Caching is no longer supported, this is both to simplify the package and to avoid issues with CRAN policies. Users are encouraged to manage their own caching solutions if needed, e.g., {targets} or save the data locally after downloading using their preferred format and methods.
Update documentation to reflect new functionality.
Improvements to the file handling and object creation to be more efficient and faster.
create_CRU_stack() and create_CRU_df() now only work with locally available files.
If you need to fetch and create a data frame or raster stack of the data, please use the new functions, get_CRU_stack() and get_CRU_stack().
R >=3.2.0 now required.
Data can be cached using either get_CRU_stack() or get_CRU_df() for later use.
Improved documentation with examples on mapping and graphing and more detail regarding the data itself.
Change the method in which files are downloaded to use httr::GET().
Ingest data using data.table::fread to decrease the amount of time necessary to run the functions.
Functions check to see if data file(s) have already been downloaded during current R session, if so data file(s) are not requested for download again.
Months are returned as a factor object in the tidy data frame.
Correct fix bug in raster object generation where the objects were incorrectly cropped.
Update documentation with ROxygen 6.0.0.
Minor edits to documentation for clarity.
Correct documentation to read that the data resolution is 10 minute, not 10 seconds.
Correct URLs in DESCRIPTION file.
Add required version for {purrr}.
Add required version for R.
Corrected URL pointing to CRU readme.txt file.
Renamed to {getCRUdata} as suggested by CRAN maintainers.
Revised description file as requested by CRAN maintainers.
Enhanced vignette.
