Convert characters to factors
to_fct(dataset, safx = 30, nuniq = 100, n = 100)
dataset | Data frame |
---|---|
safx | Ratio of number of rows to number of unique values |
nuniq | Cutoff for number of unique values |
n | Cutoff for small dataset |
Convert columns of type character to factors based on a set of rules. By default columns will be converted for small datasets (<= 100 rows) with more rows than unique values. For larger datasets, columns are converted only when the number of unique values is <= 100 and there are 30 or more rows in the data for every unique value
