Hi
Thank you for responding to my query.
So I enter the command- install.packages("devtools")
And this is what I get -
Warning in install.packages :
unable to access index for repository https://cran.rstudio.com/src/contrib:
cannot open URL 'https://cran.rstudio.com/src/contrib/PACKAGES'
Installing package into ‘C:/Users/Sharma JI/Documents/R/win-library/4.0’
(as ‘lib’ is unspecified)
Adding the remaining command in the next message
I'm sending the response just for devtools, but I get the same message for other packages too-whether it's github, or dplyr or shiny.
I had, for the first time run RStudio through D:/ in my laptop, and the packages had installed then. After some commands weren't running as mentioned and I realized my error I uninstalled and reinstalled it via C:/ drive. It is now that none of the packages are loading.
