Hi, Is this what you are looking for?
a = c(528,528,528,528,708,708,529,1208,423,1506,321) paste(substr(a,1,nchar(a)-2),substr(a,nchar(a)-1,nchar(a)),sep="/") [1] "5/28" "5/28" "5/28" "5/28" "7/08" "7/08" "5/29" "12/08" "4/23" "15/06" "3/21" Martyn -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of btc1 Sent: 15 July 2010 18:22 To: r-help@r-project.org Subject: [R] Cut a within elements by length, not value, of vectors Hello, I have a vector, "dates", as a series of 3 digit elements, i.e. > date [1] 528 528 528 528 528 528 528 528 528 528 528 528 708 708 708 708 708 708 [19] 708 708 708 708 529 529 529 529 529 529 529 529 529 529 529 529 529 529 [37] 529 624 I need to convert them into julian, but have to insert a "/" or "-" after the first number within each element of the vector (5/28 5/28 etc). Found plenty functions to replace by a pattern but not to cut by a certain number of digits with an element. Alternately, if I could run all the elements into one long vector and then cut every one then two digits, that would work as well. Thanks. -- View this message in context: http://r.789695.n4.nabble.com/Cut-a-within-elements-by-length-not-value- of-vectors-tp2290440p2290440.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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. ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.\ _...{{dropped:12}} ______________________________________________ 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.
