how can remove na values vector? i have huge vector has couple of na values, , i'm trying find max value in vector (the vector numbers), can't because of na values. how can remove na values can compute max? trying ?max , you'll see has na.rm = argument, set default false . (that's common default many other r functions, including sum() , mean() , etc.) setting na.rm=true you're asking for: d <- c(1, 100, na, 10) max(d, na.rm=true) if want remove of na s, use idiom instead: d <- d[!is.na(d)] a final note: other functions (e.g. table() , lm() , , sort() ) have na -related arguments use different names (and offer different options). if na 's cause problems in function call, it's worth checking built-in solution among function's arguments. i've found there's usually 1 there.
