gc_get_colour: Fetching GlobColour products

In herrmannrobert/GlobColouR: R client for GlobColour products

Description

Function downloads the requested GlobColour product, given as file directories created by gc_get_option.

Usage

gc_get_colour(query, openFile = FALSE)

Arguments

query	character or vector giving the file directories.
openFile	logical, if TRUE, function opens previously downloaded file (see Details). If FALSE, files are saved to working directory (default).

Details

Required file directories can either be generated by gc_get_colour or, if known, manually created. Note that the quantity of file directories is dramatically correlated with download time.

If openFile is set TRUE the function creates a temporary file (see tempfile), which is immediately opend after download (see Examples). Method requires length(query) < 2. For further details see nc_open and readPNG.
