[R] buit a package using Rstudio and existing R files

[Karim Mezhoud]

Dear All,
I am trying to built for the first time a package. I am following this
tutorial:
https://support.rstudio.com/hc/en-us/articles/200486488-Developing-Packages-with-RStudio

I create a new Project (package) and I added 44 .R sources files
(functions).
After, I got error message when I built and reload the project (please, see
bellow).

Any suggestion?

I need to fill the doc informations (title, manual, vignette, description).
Can I do these directly from Rd files located in Man folder?
Thanks!

Karim
