I have microsoft ML server/ R Client installed in my system. But when I try to load packages, it is giving version errors like the following :

namespace ‘stringi’ 1.1.6 is being loaded, but >= 1.1.7 is required
namespace ‘Rcpp’ 0.12.14 is already loaded, but >= 0.12.16 is required

This issue exists in a lot of packages. So I tried looking at the repository.

 getOption("repos") 

 CRAN   "https://mran.microsoft.com/snapshot/2018-01-01" 
 CRANextra  "http://www.stats.ox.ac.uk/pub/RWin"

And I tried downloading only from the 1st link but still, it is downloading the old version only.

Since you are using R Open, you are using checkpoint?

Checkpoint freezes your mran repository to a specific snapshot in time. it looks like your mran is frozen to 2018-01-01

https://mran.microsoft.com/snapshot/2018-01-01

change the check point to today and update_packages()

update_packages()

NOTE: this only works from packages that are installed from mran, if you install a package using devtools::install_github() the package will not come from the snapshot.

More info on this

https://mran.microsoft.com/documents/rro/reproducibility

Look at the FAQ for the following questions.

Why can't I update to or install the latest CRAN packages?

Can I change the default repository for Microsoft R Open?

https://mran.microsoft.com/faq#static-repos

install.packages() recommends that you always run updated_packages() before installing a new package to ensure that the latest are installed.

Try the following: (or read the faq to change your repository permanently)

checkpoint("2018/09/03")
update_packages()

  • But it should work if I download all package from same snapshot period right? Im not using any checkpoint but getOption("repos") gives : CRAN "https://mran.microsoft.com/snapshot/2018-01-01" . So Im asking why does it matter since I'm downloading all from same date – Dom Jo Sep 04 '18 at 03:36
  • What package are you trying to load? Checkpoint only works for mran packages, if you installed a package directly from github it will not be supported. – Carlos Santillan Sep 04 '18 at 03:54
  • I did not download anything from Github – Dom Jo Sep 04 '18 at 06:26
  • Default repository is mran. Do you know how to remove all R packages at once, so I can reinstall them? – Dom Jo Sep 04 '18 at 06:28
  • I changed the checkpoint to 2018-09-01 but its still showing as 2018-01-01 in getOption("repos") – Dom Jo Sep 04 '18 at 07:38
