rasterTmpFile: Temporary files
Description
Functions in the raster package create temporary files if the values of an output RasterLayer cannot be stored in memory (ram). This can happen
when no filename is provided to a function and in functions where you cannot provide a filename (e.g. when using 'raster algebra').
Temporary files are automatically removed at the start of each session. During a session you can use showTmpFiles
to see what is there and removeTmpFiles
to delete all the temporary files. rasterTmpFile
returns a temporary filename. These can be useful when developing your own functions.Usage
rasterTmpFile()
showTmpFiles()
removeTmpFiles()
Value
rasterTmpFile
returns a temporary file name (for use in functions)
showTmpFiles
returns the names (.grd only) of the files in the temp directory
removeTmpFiles
returns nothing
Details
The default path where the temporary files are stored is returned by showOptions()
; you can change it (for the current session) with setOptions.
