Source file pdoc.exe rstudio

When I use R laptop and always get an error like

'pandoc.exe.. out of memory'.

      

        
        
        
      

    

And the block of code seems to freeze and cannot be executed. Can someone educate me on how this works and why is this happening? I tried to solve these problems. It doesn't seem so obvious. I wonder if there is an easy way to increase laptop memory size. I still have a lot of space on my ram ... Thanks.
