Hi all. Suppose I have a vector of strings ie: ["12384", "TYU123123", "AVC3939", "hhr1919", "TYU0029"] Is there an efficient method that would allow me to return a vector of the position of strings that start with "TYU"? So essentially, I would like to get back in return [2, 5]. Anyways, any help with be greatly appreciated! -- View this message in context: http://www.nabble.com/Vector-of-string-tp24167271p24167271.html Sent from the R help mailing list archive at Nabble.com.
Try this:
s <- c("12384", "TYU123123","AVC3939",
"hhr1919", "TYU0029")
grep("^TYU", s)
