Hi,
I am writing a program that returns the a vector of the most recent R files in
a given dir.
The files are named like "f1.R", "f2.R", and sometimes "f3a.R". I want to use
the resulting
vector to easily source() all the most recent file versions of a given dir.
Here's what I've cooked up till sofar:
library(plyr)
rfiles <- Sys.glob("G:\\temp\\*.R")
rfiles2 <- data.frame(rfiles, mtime = ldply(rfiles, "file.info")[,"mtime"])
rfiles2$basename <- gsub("([0-9]+[a-z]?)\\.R", "", rfiles)
srt <- with(rfiles2, order(rfiles, mtime))
rfiles2[srt,][!duplicated(rfiles2$basename),] # does not work
Thank you in advance!
Cheers!!
Albert-Jan
