I just upgraded to R 4.0.0 and I am now trying to reinstall the packages I use. But when I try to do so in RStudio, I have the following warning:
Warning in install.packages: converting NULL pointer to R NULL
I also had this sort of warning later when running a shiny app:
Warning in .Call("rs_registerShinyFunction", params): converting NULL pointer to R NULL
Where does this come from? How can I fix it?
