Hello every one

I tried to load cummeRbund package, it gave me the error (Error: package ‘ggplot2’ could not be loaded). I tried to load the ggplot2, it gave the following error (Error: package or namespace load failed for ‘ggplot2’). It was working fine and properly before, now starts giving me these errors. Any tips or suggestions. I appreciate your help Shaima
