[R] How to import timestamps from emails into R

[Gabor Grothendieck]

Try this:


Lines <- "Sun, 14 Jun 2009 07:33:00 -0700
Sun, 14 Jun 2009 08:35:10 -0700
Sun, 14 Jun 2009 21:26:34 -0700
Mon, 15 Jun 2009 19:47:47 -0700
Wed, 17 Jun 2009 21:50:41 -0700"

# L <- readLines("myfile.txt")
L <- readLines(textConnection(Lines))
tt <- as.POSIXct(L, format = "%a, %d %b %Y %H:%M:%S")
