Joins a vector into prose ("A", "A and B", "A, B, and C"). Unlike `knitr::combine_words()`, an empty
input returns `none` rather than `""`, so narrative text never ends up with a hole in it.
Usage
words_list(x, none = "none", and = "and")
Arguments
- x
A vector (converted to character). `NA` entries are dropped.
- none
Text returned when nothing is left.
- and
The joining word (default `"and"`; use `"or"` for alternatives). Surrounding spaces are ignored.
Examples
words_list(c("age", "sex", "BMI"))
#> [1] "age, sex, and BMI"
words_list(character())
#> [1] "none"
words_list(c("a", "b"), and = "or")
#> [1] "a or b"
