Compute Correlation Index
ds_correlation(.data, .cols, .name)
correlation(..., .data = dplyr::across(everything()))tidy-select
Columns to compute the measure with. Must be at least 2 columns. If more than 2, treats
first column as first group and sum of other columns as second.
name for column with Correlation index. Leave missing to return a vector.
