This is useful way of patching together factors from multiple sources that really should have the same levels but don't.

fct_c(fs, ...)

## Arguments

fs A factor, or list of factors. Individual factors

## Examples

fa <- factor("a")
fb <- factor("b")
fab <- factor(c("a", "b"))

c(fa, fb, fab)#> [1] 1 1 1 2fct_c(fa, fb, fab)#> [1] a b a b
#> Levels: a b
# You can also pass a list of factors as the first argument
fs <- list(fa, fb, fab)
fct_c(fs)#> [1] a b a b
#> Levels: a b
