If I understand correctly, you can use which( ,arr.ind=TRUE):
Assuming that you start with a data frame,
dat <- as.data.frame(matrix(runif(30), ncol=5))
nm <- names(dat)
cormat <- cor(dat)
cormat[lower.tri(cormat, diag=TRUE)] <- NA
idx <- which(cormat > 0.4, arr.ind=TRUE)
idx
cbind(nm[idx[, "row"]], nm[idx[, "col"]])
will give you the pairs.

Dear R users,
Simple question. Can anyone help with the code that would allow me to view only the variables who's correlation output is >0.8?
This is the code I'm using to date
cor(data, method="spearman")
Kind regards
Krys
