Hello! I need to calculate the maximum of each row of a data frame. This works:
x <- data.frame(a = 1:5, b=11:15, c=111:115) x do.call(pmax, x) [1] 111 112 113 114 115 However, how should I modify it if my data frame has NAs? I'd like it to ignore NAs and return the maximum of all non-NAs in each row: x <- data.frame(a = c(1:5), b=11:15, c=c(111:114,NA)) x I'd like it to return: [1] 111 112 113 114 15 Thanks a lot! -- Dimitri Liakhovitski ______________________________________________ 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.
