cor() btwn columns in two matrices - no complete element pairs
...sponding
columns in two matrices with identical dimensions but different data. 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 apologis...
