There are no options to get Splus behaviour here, but I think you'll get what you want with this code: badindices<-sapply(tempdata,function(x)(bdind<-which(is.na(x)))[1]) I'm not sure why you're creating the bdind variable; you could get the same thing in badindices without that side effect with the simpler badindices<-sapply(tempdata,function(x) which(is.na(x))[1]) Duncan Murdoch ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
