cc_data_read: Read CCAFS data

Description

Read CCAFS data

Usage

cc_data_read(x, unreadable = "filter")

Arguments

x

A ccafs_files object, the output from a call to cc_data_fetch()

unreadable

(character) what to do when unreadable files are passed in. default is to filter them out and proceed ("filter") - alternatively, you can choose "stop", in which case we'll stop with a message.

Value

RasterLayer or RasterStack class object. See their help files in raster package documentation.

Details

Look in rappdirs::user_cache_dir("ccafs") for what files are cached and to delete any.

cc_data_fetch() downloads data to your machine, and this function reads the data into your R session.
