Is it possible to set na.rm to TRUE globally?

Question

For commands like max the option na.rm is set by default to FALSE. I understand why this is a good idea in general, but I\'d like to t

Answer 1

For my R package, I overwrote the existing functions mean and sum. Thanks to the great Ben (comments below), I altered my functions to this:

mean <- function(x, ..., na.rm = TRUE) {
  base::mean(x, ..., na.rm = na.rm)
}

After this, mean(c(2, NA, 3)) = 2.5 instead of NA.

And for sum:

sum <- function(x, ..., na.rm = TRUE) {
  base::sum(x, ..., na.rm = na.rm)
}

This will yield sum(c(2, NA, 3)) = 5 instead of NA.

sum(c(2, NA, 3, NaN)) also works.
