Hello
I just reinstalled R, Rtool, and RStudio. Then I ran install.pacakges("sp"). And it is giving me a version error when I ran the following:
> install.packages("sp")
Installing package into ‘C:/Users/User/OneDrive/Dokumen/R/win-library/4.1’
(as ‘lib’ is unspecified)
trying URL 'https://cran.rstudio.com/bin/windows/contrib/4.1/sp_1.4-7.zip'
Warning in install.packages :
cannot open URL 'https://cran.rstudio.com/bin/windows/contrib/4.1/sp_1.4-7.zip': HTTP status was '404 Not Found'
Error in download.file(url, destfile, method, mode = "wb", ...) :
cannot open URL 'https://cran.rstudio.com/bin/windows/contrib/4.1/sp_1.4-7.zip'
Warning in install.packages :

Hope someone can help me.
