I have a large data frame 48:2185 with different numbers. I would like to add only one row at the very top of my data frame with 0's or NA's. I don't know which approach to use. Should i create 2 different data frames and merge them? Ive also tried the rbind command with no luck. I would appreciate some help to achieve what I'm trying to create. Thanks!
Say your dataframe is named 'dat'. x <- rep(NA, ncol(dat)) dat <- rbind(x, dat) will insert a row of NA's. x <- rep(0, ncol(dat)) dat <- rbind(x, dat) will insert a row of 0s. If any of your variables are not numeric or character, you'll get a warning. -Peter Ehlers ______________________________________________ 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.
