This is a useful way of patching together factors from multiple sources
that really should have the same levels but don't.
Arguments
- ...
<dynamic-dots> Individual
factors. Uses tidy dots, so you can splice in a list of factors
with !!!.
Examples
fa <- factor("a")
fb <- factor("b")
fab <- factor(c("a", "b"))
c(fa, fb, fab)
#> [1] a b a b
#> Levels: a b
fct_c(fa, fb, fab)
#> [1] a b a b
#> Levels: a b
# You can also pass a list of factors with !!!
fs <- list(fa, fb, fab)
fct_c(!!!fs)
#> [1] a b a b
#> Levels: a b
