[R] correlation between matrices - both with some NAs

Hi everyone,

I'm having trouble applying the Cor() function to two matrices, both of which contain NAs. I am doing the following:

a<-cor(m1, m2, use="complete.obs")

... and I get the following error message:

Error in cor(m1, m2, use = "complete.obs") :   no complete element pairs

Does anyone know how I can apply a correlation, ignoring any NAs?

Thanks,

rcoder
