I would like to extract first date from a string: > txt <- "first date is 05.12.2009. Second date is 06.12.2009." > txt [1] "first date is 05.12.2009. Second date is 06.12.2009."
I tried: > sub("^.*?\\s(\\d{1,2}\\.\\d{1,2}\\.\\d{4})", "\\1", txt, extended=T, perl=T) [1] "05.12.2009. Second date is 06.12.2009." > How to modify this? -J ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
