Hi, the argument use should be: use="p" (for pairwise complete obs.)

The problem is that the matrices contain NAs in different locations. I am using the following code to try to calculate correlations between complete sets of data: #Code start maxcol<-ncol(mat1) for (i in 1:maxcol) { corr_results[1,i]<-cor(mat1[,i],mat2[,i], use="complete.obs") } #Code end ...but I get the following error message: Error in cor(mat1[,i], mat2[,i], use="complete.obs") : no complete element pairs Is there something I'm not including in the 'cor' parentheses? I apologise for not including the true original data frames.
