Hello,
I'm trying to do cor(x1,x2) and I get the following error:
Error in cor.default(x1, x2) : missing observations in cov/cor
A few things:
1. I've used cor() many times and have never encountered this error.
2. length(x1) = length(x2)
3. is.numeric(x1) = is.numeric(x2) = TRUE
4. which(is.na(x1)) = which(is.na(x2)) = integer(0) {the same goes for
is.nan()}
5. I also try cor(x1,x2, use = "all.obs") and get the same error.
What can be going wrong?
