WARNING: R: 1: package ‘methods’ was built under R version 3.6.1

Hi Folks,

we've installed the R-core.x86_64 RPM from the EPEL Repository on Red Hat 7. The Version of R is 3.6.0 (2019-04-26). If we run a test program now then we get some warning:

52         proc iml;
NOTE: IML Ready
53             submit /R;
54                print("Hello World!")
55            endsubmit;
WARNING: R: 1: package ‘methods’ was built under R version 3.6.1

WARNING: R: 5: package ‘graphics’ was built under R version 3.6.1 
WARNING: R: 6: package ‘stats’ was built under R version 3.6.1 
56         quit;

NOTE: PROCEDURE IML used (Total process time):
      real time           0.28 seconds
      cpu time            0.01 seconds

What can we do to avoid this warning (except installing R version 3.6.1 😉 )? We use the SAS Version 9.4M6.

Cheers,

Klaus

What do you get if you run the program in RGui?

We do not get a warning:

> print("Hello World!")
[1] "Hello World!"

I don't know. The usual way these warnings occur is when you install a version of R and then later install packages from a more recent version. But I think the packages in his message are all “core packages” that are auto-created and auto-loaded by R. When you compiled the R source, did you also compile the packages, or did you download them later?

Here is a link to the installation instructions for installing R on Linux: https://support.sas.com/documentation/installcenter/en/iktkintrii/64028/PDF/default/install.pdf

Make sure that the R_HOME variable in SAS and RGui are the same. You can check the value with the R function

Sys.getenv("R_HOME")

Hi Rick,
That was the perfect hint! R_HOME was different in Rgui and SAS.... A relict from an old Anaconda installation.

Thanks!

Cheers, Klaus
