Convert characters to factors

to_fct(dataset, safx = 30, nuniq = 100, n = 100)

Arguments

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

Details

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

Examples

tibble(a = c("a", "b"), b = c("a", "a"), c = 1:2) %>% to_fct()
#> # A tibble: 2 × 3
#>   a     b         c
#>   <chr> <fct> <int>
#> 1 a     a         1
#> 2 b     a         2
