Using count on data frame with a column named freq

[stefanhillmann]

If you use the function count on a data frame that contains a column named 'freq', the method uses automatically the column 'freq' as weighting variable.

The behaviour occurs from lines 55 to 58 in count.r:
if (is.null(wt_var) && "freq" %in% names(df)) {
message("Using freq as weighting variable")
wt_var <- "freq"
}

Please add this very special behaviour to the method documentation, or remove it. I believe removing is the better solution as count(my_data, c('col_1'), wt_var = 'freq') does exactly the same thing...

Best,
Stefan
