The installation of Shinychat stopped due to an error I do not understand. I have included the results of the pak command

I think you may need to install the appropriate version of RTools: https://cran.r-project.org/bin/windows/Rtools/ Sorry for the inconvenience. This won’t be necessary once shinychat goes to CRAN.

Yes, You are right! Updating Rtools solved my problem. Thanks so much!
