trying to install packages in Rstudio

When I'm trying to install packages, I typed in (quantmod lubridate xts Rcpp RcppArmadillo reshape2 ggplot2 scales grid coda) and I got these errors:

Warning in install.packages :
package ‘grid’ is not available (for R version 4.0.2)
Warning in install.packages :
package ‘grid’ is a base package, and should not be updated

Can anyone help me to solve the problem? I just started learning R, so I basically know nothing about it, can you be specific as you can? Thank you!

I would suggest focussing on one package you want to install at a time.
you didn't share what line of code resulted in the particular warning you posted (warning/not error).
If its

install.packages("grid")

then, simply omit that, don't try to do it, if you have R.4.0.2 then you have grid already, as package ‘grid’ is a base package, and should not be updated with install.packages

I click packages and then click install, and type in

quantmod lubridate xts Rcpp RcppArmadillo reshape2 ggplot2 scales grid coda

well , try not putting grid (the penultimate one)
