Hello everyone-

I have a 3-d array with the 1st dimension being monthly mean data that
I would like to correlate with some time series index, for example, and 
save the coefficients in an array.

The code I am currently running is....


   rData <- array(0,c(73,144))   # array to store results
   for (i in 1:73) {
        for (j in 1:144) {
              rData[i,j] <- cor(slp[,i,j],y)
        }
    }

    Rather than running this analysis embedded with two outer loops, are =
    there any more efficient ways of doing this?
    Many thanks!
