How to build an R package base on other package？

Question

I am trying to build an R package. But now my function has used some function from package stringr. Could anyone tell me how can I add stringr in to my package? Thank you.

Answer 1

The function you have used should be added to roxygen documentation. For example, if you used the function stringr::str_extract(), you can add-

#' @importFrom stringr str_extract()

And then run roxygen2::roxygenise() and you should see this function added to your NAMESPACE file. You can read about this in Hadley Wickham's (freely available book on how to make R packages): r-pkgs.had.co.nz/namespace.html
