[R-SIG-Mac] File creation date

[Julin Maloof]

Hi Loren,

Try the following.  You need to have XCode developer tools installed.  Assumes that you working directory is where the files of interest are.  Otherwise add a path to the ls command.



files <- system("ls",intern=T)

date <- vector(mode="character",length=length(files))

names(date) <- files

for (f in files) {
	date[f] <- system(paste("/Developer/Tools/GetFileInfo -d '",f,"'",sep=""), intern=T)
	}
