I think this is really answered already in my previous post but just in case
try this:
> res1 <- t(apply(mat1, 1, cor, t(mat2)))
> res2 <- cor(t(mat1), t(mat2))
> all.equal(res1, res2, check.attributes = FALSE)
[1] TRUE

I'm calculating correlations between two matrices
mat1 <- matrix(sample(1:500,25), ncol = 5,
dimnames=list(paste("mat1row", 1:5, sep=""),
paste("mat1col", 1:5, sep="")))
mat2 <- matrix(sample(501:1000,25), ncol = 5,
dimnames=list(paste("mat2row", 1:5, sep=""),
paste("mat2col", 1:5,
