NA when indexing vectors
Maybe you mean: x[which(x>=2)] El jue, 21-05-2009 a las 14:34 -0400, Jorge Ivan Velez escribi?:
Hi, Try: which( x>=2 ) HTH, Jorge On Thu, May 21, 2009 at 2:28 PM, Szilard <szilard.mailinglists at gmail.com>wrote:
Hello: Is there a more natural way to get all elements that satisfy a condition when there are NAs in the sample?
x=c(1,2,NA)
x>=2
[1] FALSE TRUE NA
x[x>=2]
[1] 2 NA ## I would expect here to get just "2"
x[!is.na(x) & x>=2] ## seems a bit cumbersome
[1] 2 Thanks, Szilard
