all columns which are not included in 'id_cols' will be used for calculation of correlation.

Value

returns a long data.frame with additional columns: 'id1' and 'id2' (referencing to the row number of the original data.frame) and 'id_cols' with appended '.x' and '.y' suffixes. The column 'value' will contain correlation coefficient
