I'm having trouble installing some packages. I previously installed data.table and had no problems. Now, when trying to install dplyr and devtools I get the following message:
Installing package into ‘[file path]’
(as ‘lib’ is unspecified)
Warning: unable to access index for repository http://cran.repo.bppt.go.id/src/contrib
Warning: unable to access index for repository http://cran.repo.bppt.go.id/bin/windows/contrib/3.2
Warning message:
package ‘devtools’ is not available (for R version 3.2.1)
I am not exactly sure how to handle this. Appreciate any help.
