Subject: Windows List of Folders?
In-Reply-To: <OF095552C2.E14D7AA9-ON86256FF2.0070A797-86256FF2.0073F7E7@fd9ns01.okladot.state.ok.us>
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
