How do I sample only non-null values in R?

Is there was a way to sample only non-null values in R? Currently, I have this code.

s <- sample(200000, replace=TRUE);
m <- mydata$myvar[s]

However, some elements of m are null. Is there such a simple command as the following?

s <- sample(200000, replace=TRUE, na.rm=TRUE);
s <- sample(mydata$myvar, replace=TRUE, na.rm=TRUE);

The documentation does not state such option exists.

Solution

  • You can just remove the NULL elements afterwards:

    m <- m[!is.null(m)]
