[R] Windows List of Folders?

[Henrik Bengtsson]

Example:

path <- system.file(package="base")
pathnames <- list.files(path, full.names=TRUE)
isDir <- file.info(pathnames)$isdir
dirs <- pathnames[isDir]
files <- pathnames[!isDir]

If you don't get the 'isDir' line, think of it as
infos <- file.info(pathnames)
isDir <- infos$isdir
