R is a programming language and free software environment for statistical computing and graphics supported by the R Foundation for Statistical Computing. The R language is widely used among statisticians and data miners for developing statistical software and data analysis. Below are links to pages that are related to R. R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and macOS.

Note:

  • This software is dependent on the following modules:

    • gcc/7.3.0

    • Due to the install process, at this moment in time, you have to explicitly load gcc before loading r. If you try loading r before gcc you will see the following message:

[]$ module load r/3.6.1
Lmod has detected the following error:  These module(s) exist but cannot be loaded as requested: "r/3.6.1"
   Try: "module spider r/3.6.1" to see how to load the module(s).

R Packages

Below we will give some guidelines on how to install and use various R packages specifically on Teton.

  • Typically, packages will be installed in your home folder, within the R folder, under the platform version x86_64-pc-linux-gnu-library, then under a major.minor version (without the patch number) folder.

~/R/
  x86_64-pc-linux-gnu-library/
    3.5/
    3.6/

  • Packages installed/built with one major.minor version will typically not work under another.

R Package: RStan

R and Intel/MKL

We have versions of r (3.6.1/4.0.2) built with the Intel compiler and related MKL (Maths Kernel Library) that follows a request relating to Improving R Performance by installing optimized BLAS/LAPACK libraries.
To use:

[]$ module load r/4.0.2-intel

[]$ R
R version 4.0.2 (2020-06-22) -- "Taking Off Again"
Copyright (C) 2020 The R Foundation for Statistical Computing
Platform: x86_64-pc-linux-gnu (64-bit)

> sessionInfo()
R version 4.0.2 (2020-06-22)
Platform: x86_64-pc-linux-gnu (64-bit)
Running under: Storage

Matrix products: default
BLAS/LAPACK: /pfs/tsfs1/apps/el7-x86_64/u/intel/18.0.1/intel-mkl/2018.2.199-pti6y2y/compilers_and_libraries_2018.2.199/linux/mkl/lib/intel64_lin/libmkl_rt.so

  • The Intel built version is dependent on the following modules core:

    • intel/18.0.1

    • intel-mkl/2018.2.199

    • The module load r/*.*.*-intel line will automatically load these modules for you.

Installing Packages to Use with Intel Version

  • The packages that you have installed for the standard versions of R will not work for the Intel version since they are built with different compilers. This means you will need to re-install the packages that you use.

  • If you potentially want to use both versions then you will need to create a second folder to install the Intel versions into.

  • This has been tested with R.3.6.1 intel version - a similar approach should apply for 4.0

On Teton, R packages are typically installed into:

~/R/
  x86_64-pc-linux-gnu-library/
    3.5/
    3.6/

One way to install the Intel packages is the following:

  • Create a folder ~/R/intel/3.6/

~/R/
  x86_64-pc-linux-gnu-library/
    3.5/
    3.6/
  intel/
    3.6/

  • Use module load r/3.6.1-intel to load the Intel version.

  • After starting R, use .libPaths(c("~/R/intel/3.6/")) to set your environment to use this folder.

    • If you run .libPaths() you should see something of the form:

> .libPaths()
[1] "/pfs/tsfs1/home/salexan5/R/intel/3.6"                          
[2] "/pfs/tsfs1/apps/el7-x86_64/u/opt/R/3.6.1/intel/R-3.6.1/library"

  • Install packages as normal e.g. install.packages("<the package's name>")

  • When running your R scripts you need to set .libPaths(c("~/R/intel/3.6/")) before loading any libraries to inform R where the appropriate packages can be found.

  • Note: Currently R Package: RStan can not be installed using the intel version.

Installing Packages: Potential Problems

Trying to install install.packages("labdsv") resulted in the following error:

/apps/u/gcc/4.8.5/intel/18.0.1-7cbw2rp/include/complex(77): error #308: member "std::complex<float>::_M_value" (declared at line 1187 of "/usr/include/c++/4.8.5/complex") is inaccessible
          _M_value = __z._M_value;
...
compilation aborted for sptree.cpp (code 2)
make: *** [sptree.o] Error 2
ERROR: compilation failed for package ‘Rtsne’

ERROR: dependency ‘Rtsne’ is not available for package ‘labdsv’
* removing ‘/pfs/tsfs1/home/salexan5/R/intel/3.6/labdsv’

This appears to be a reasonably common problem:

and is essentially a result of conflicts between compilers when using complex data types with the workaround of disabling the diagnostic error.
To resolve the issue, create and/or update the ~/.R/Makevars file by adding the following lines:
