A simple reproduciple example always works, # create sample data df <- data.frame(a = round(runif(100) * 10), b = round(runif(100) * 10)) df[which(df[,2] == 2),2] <- NA # add NA to second column apply(df, 2, function(x) sum(x == 1, na.rm = TRUE)) ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
