Hello, with Sys.time() you get the following string: "2011-11-15 16:25:55 GMT" How can I extract the following substrings: year <- 2011 month <- 11 day_time <- 15_16_25_55 Cheers, Syrvn -- View this message in context: http://r.789695.n4.nabble.com/Extract-pattern-from-string-tp4073432p4073432.html Sent from the R help mailing list archive at Nabble.com.
Extract pattern from string
3 messages · syrvn, Justin Haynes
take a look at the structure of what Sys.time returns. str(Sys.time) and now at ?strptime!
format(Sys.time(),format='%d-%H-%M-%S')
[1] "15-09-55-55"
format(Sys.time(),format='%Y')
[1] "2011"
format(Sys.time(),format='%m')
[1] "11"
Hope that helps, Justin
