Re: [R] Summing with NA

Slightly longer method, but works as well. z <- c(-12,-9) e <- c(-2,0) k <- c(NA,NA) x <- c(z,e,k) x1 <- which(x!="NA",arr.ind=TRUE) # get elements which are not NA x2 <- x[x1] sum(x2) [1] -23 -- Muhammad tj wrote: Hi all, May I request for your help if you have time and if you have an i

Re: [R] Summing with NA

k <- c(NA, NA) z <- c(-12, -9) e <- c(-2,0) sum(na.omit(c(z, e, k))) Will this do the trick? Why are you summing in a sum() sum(k+z+e) On Mon, Mar 22, 2010 at 8:51 PM, tj wrote: > > Hi all, > May I request for your help if you have time and if you have an idea on how > to do this.  I want to a

[R] Summing with NA
