Dear all, I am trying to apply the aggregate() function to calculate correlations for subsets of a dataframe. My argument x is supposed to consist of 2 numerical vectors, which represent x and y for the cor() function. The following error results when calling the aggregate function: Error in FUN(X[[1L]], ...) : supply both 'x' and 'y' or a matrix-like 'x'. I think the subsets aggregate puts into cor() are sort of list types and therefore can't be handled by cor().
as.matrix() will probably help, but since you have not specified your reproducible code, we cannot show how to change that.

Can anyone provide me with a solution?
