r - How to create a string with sprintf

Question

I would like to create a string like JSON format using the sprintf function.
I use this code:

elements_list = sprintf('{"id":"%s",
                          "top": "%s",
                          }', 5, 4)

But the result when I print the string is like this:

"{"id":"5","top":"4"}"

with "" character everywhere, any help?

Thanks!

Answer 1

This should work - you don't need all the double-quotes inside the expression:

elements_list = sprintf('{id:%s top: %s}', 5, 4)
elements_list
# [1] "{id:5 top: 4}"
