Splitting is easy: strsplit(as.character(x$ID), "/")
That produces a list with four elements, each of which is a character vector. R does not have a representation for "sub-columns" so you will have to be clearer about how you want to represent the data and what you are planning to do with it. ---------------------------------------------- David L Carlson Associate Professor of Anthropology Texas A&M University College Station, TX 77843-4352 > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- > project.org] On Behalf Of Sapana Lohani > Sent: Monday, August 27, 2012 1:41 PM > To: R help > Subject: [R] ?nchar ?strsplit > > Hi, my data frame is > > x<-data.frame(ID=c("abc/def","abc/def/ghi","abc","mno/pqr/st/ab")) > > I want to split my column ID using "/" as the place to split.
