Apptainer Interactive applications using MATLAB and R
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

**Apptainer Matlab Interactive:**

To pull the MatLab container, 

::

     $ apptainer pull docker://mathworks/matlab 

This pulls the container and converts it to a SIF container matlab_latest.sif. To launch MatLab 

::

     $ bsub -q general -P hpc -Is apptainer run /nethome/rxp1166/matlab_latest.sif
       Job is submitted to <hpc> project.
       Job <28292508> is submitted to queue <general>.
       <<Waiting for dispatch ...>>
       <<Starting on n255>>

Apptainer R Interactive
^^^^^^^^^^^^^^^^^^^^^^^

The most popular library for R is the Tidyverse, popular Docker containers for R, including a pre-built one with Tidyverse so you can grab the latest tagged container from Docker hub and it takes few seconds wait for until creation of sif image . 

:: 

     $ apptainer pull docker://rocker/tidyverse:4.0.1 

 

Now run the container's R binary when you successfully load the Tidyverse. 

 
.. code:: bash

          $ bsub -q general -P hpc -Is apptainer run tidyverse_4.0.1.sif R
            Job is submitted to <hpc> project.

**alternative approach to pull R image**

 ::

     $ apptainer pull docker://r-base:4.0.3 
     $ apptainer run r-base_4.0.3.sif R
