Issues with R configuration and SAP PA Expert Mode

Hi

I have previously configured SAP PA expert mode with R. Now I have loaded some new packages in that same version of R. And when I am trying to install those packages in SAP PA 2.2 expert mode, it gives the below attached error.

Now my already created  custom R algorithms have stopped working because of this error.

Can anyone help me out!
