| combine_words {knitr} | R Documentation |
When a value from an inline R expression is a character vector of multiple
elements, we may want to combine them into a phrase like a and b, or
a, b, and c. That is what this a helper function does.
combine_words( words, sep = ", ", and = " and ", before = "", after = before, oxford_comma = TRUE )
words |
A character vector. |
sep |
Separator to be inserted between words. |
and |
Character string to be prepended to the last word. |
before, after |
A character string to be added before/after each word. |
oxford_comma |
Whether to insert the separator between the last two elements in the list. |
If the length of the input words is smaller than or equal to 1,
words is returned. When words is of length 2, the first word
and second word are combined using the and string. When the length is
greater than 2, sep is used to separate all words, and the and
string is prepended to the last word.
A character string marked by xfun::raw_string().

combine_words(c("a", "b", "c"), before = "\"", after = "\"", oxford_comma = FALSE)
