Hi Joshua,

SORRY for not making that clear. I wish to have the correlation values
between each column of my "file" with the "LGD". For example:

cor (Column 1, LGD)
cor (column 2, LGD) ... so on.

The first one you have provided is producing an error :

> sapply(file[1:47231, 3:10], FUN = cor, y = rep(LGD, 47231), method =
"pearson")
Error in FUN(X[[1L]], ...) : incompatible dimensions
Cheers,
Chintanu
