Reorder factors levels by first appearance or frequency

fct_inorder(f, ordered = NA)
fct_infreq(f, ordered = NA)

## Arguments

f |
A factor |

ordered |
A logical which determines the "ordered" status of the
output factor. `NA` preserves the existing status of the factor. |

## Examples

f <- factor(c("b", "b", "a", "c", "c", "c"))
f

#> [1] b b a c c c
#> Levels: a b c

fct_inorder(f)

#> [1] b b a c c c
#> Levels: b a c

fct_infreq(f)

#> [1] b b a c c c
#> Levels: c b a

fct_inorder(f, ordered = TRUE)

#> [1] b b a c c c
#> Levels: b < a < c
