Dear all,
I would like to capture the NA values as produced from my code
the str over the return values return
int 61
int 65
int 69
int 73
int 101
int NA
int NA
it looks like that I am getting returned some integer values that
are NA and I want to have an if statement for catching those
which is the right operator for checking these int NA values in R?
If you have a vector of mode 'integer' (or numeric) you can get their
index locations with:
which(is.na(vec))
Logical tests for any NA's would be:
!length(which(is.na(vec)))
or
sum(is.na(vec))==0
or perhaps the most self-documenting method:
any(is.na(vec))
