How to find out which functions from which packages were used in *.rmd file ?

[Andrzej]

Is there a way to find out which functions from which packages were called within *.rmd file ?

Something like function list.functions.in.file from the {NCmisc} package but for *.rmd files ?
Thank you for help.

Hi @Andrzej,
Not sure if you can do this directly, but you could extract all the R code from the .Rmd file first and then run list.functions.in.file() on the resultant file. See:

Hi @DavoWW,

Thank you, this is working like a charm:

knitr::purl("main.Rmd")

list.functions.in.file("main.R")

and then in console there is a list of all functions that are inside "main.R" file:

I collected other resources for the sake of completeness:
