The programming language R(4.0.3) is available in SQUID.
 

How to use

Environmental setting

    You need to set up the environment using "environment modules".

    $ module load BaseCPU
    $ module load BaseR

     
    Also, specify a large work area as the installation destination for the library.
    In the following example, we create a directory named R_lib under the work area and specify it as the installation directory for the library.

    $ mkdir /sqfs/work/[group name]/[user name]/R_lib
    $ export R_LIBS=/sqfs/work/[group name]/[user name]/R_lib

 

package install

    Any package can be installed on the front-end node of SQUID.
    Since connection to the outside world is prohibited from the computation node, please install the packages necessary for the calculation on the front-end node beforehand.
     
    The steps to install the "data.table" package on the front-end node are shown below.

    Launch the R prompt.
    $ R
     
    Install the data.table package.
    > install.packages("data.table")
     

    Displays the installed packages
    $ library()
      パッケージ  （ライブラリ ‘/sqfs/work/【グループ名】/【ユーザ名】/R_libs’ 中):
    data.table              Extension of data.frame

     

Execute R script in SQUID

    .
    Please run the script as a batch job when using R. The following is an example of a job script when using R. The R script file (file.R) is given as the input file.
