set.file.extension {RSAGA} | R Documentation |
Function get.file.extension
determines the file extension,
set.file.extension
changes it, and default.file.extension
changes it only if it is not already specified.
set.file.extension(filename, extension, fsep = .Platform$file.sep) get.file.extension(filename, fsep = .Platform$file.sep) default.file.extension(filename, extension, force = FALSE)
filename |
character vector: file name(s), possibly including paths
and extensions; a file name ending with a "." is interpreted
as having extension "" , while a file name that doesn't
contain a "." is interpreted has having no extension |
extension |
character string: file extension, without the dot |
fsep |
character: separator between paths |
force |
logical argument to default.file.extension :
force the file extension to be extension (same result
as set.file.extension ), or only set it to extension
if it has not been specified? |
character vector of same length as filename
