Re: [R] How would i sum the number of NA's in multiple vectors

mattbju2013 wrote Hi guys this is my first post, i need help summing the number of NA's in a few vectors for example.. c1-c(1,2,NA,3,4) c2-c(NA,1,2,3,4) c3-c(NA,1,2,3,4) how would i get a result that only sums the number of NA's in the vector? the.result.i.want-c(2,0,1,0,0) See

Or faster (both computational speed and amount of code): colSums(is.na(rbind(c1, c2, c3))) On Thu, Oct 17, 2013 at 4:34 AM, Carl Witthoft c...@witthoft.com wrote: mattbju2013 wrote Hi guys this is my first post, i need help summing the number of NA's in a few vectors for example..
