R retain strings when converting vectors to character vectors to submit to API

Question

Ok, I suspect the answer to this question will uncover my ignorance but here it goes:

I have this input_vector of strings

input_vector <-c("string1","string2")

And I need to pass these items to a very complex API query which requires the " to be included. If I do this stringi::stri_paste(input_vector, collapse = ',') then the output is not usable

"string1,string2"

What I really need is

"string1","string2"

How do I do this?

Answer 1

paste(shQuote(input_vector), collapse = ",")

Answer 2

You can use:

paste0('"', input_vector, '"', collapse = ',')
#[1] "\"string1\",\"string2\""

To view the actual string use cat :

cat(paste0('"', input_vector, '"', collapse = ','))
#"string1","string2"
