R install package loaded namespace

Question

I would like to install the package plotly in RStudio and got a error message.

install.packages(\"~/Desktop/plotly_4.5.2.tar.gz\", repos = NULL, type = \"source\

Answer 1

sometimes you just did not restart your R studio after update. For example,

update.packages(ask=F)

After this, you should restart your R studio. Then

devtools::install_github("RcppCore/Rcpp")
