When I install and library rmarkdown version 2.3, the function convert_ipynb is not visible in the namespace for the package. I went to the GitHub site for markdown and saw that the code for convert_ipynb is in jupyter.R but when I look in NAMESPACE this file is not exported.
In the R/R-Studio help index for the markdown package, convert_ipynb does not appear as a topic. (Strangely, however, I can do a global search for the function name and the help page for the function does come up.)
Am I mistaken in thinking that convert_ipynb should be visible in the namespace?
That's helpful: I was able to run the function that way, which solved my problem. Perhaps it is my misunderstanding, but I thought that ":::" was a way of accessing a package's internal functions. I had the impression that convert_ipynb was intended to be a "public" function, available after library(rmarkdown) or by using rmarkdown::convert_ipynb().
