Hi, I have a large data frame and within this there is one column which contains individual codes (eg. 1.1234.2a.2). I am splitting these codes into their 4 components using strsplit (eg. "1", "1234", "2a", "2"). However there are some individual codes which do not have a last component (eg. 2.4356.3b. ), I want to give these codes a "1" as their last component (eg. 2.4356.3b.1) but I can't get it to work.
This is my example and attempt: sim.code<-c("1.1234.1a.1","1.1234.1a.2","1.3245.2c.5","4.6743.3c.","4.3254.6b.4","3.5463.2a.") sim.val<-c(4,5,3,6,4,7) sim.df<-data.frame(sim.code,sim.val) sim.df$sim.code2<-sub(".$",".1",sim.df$sim.code) sim.df but this changes all the ends to ".1" Thanks, Chris -- View this message in context: http://r.789695.n4.nabble.com/Substitute-value-tp4660699.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.
