I also experienced this problem, for me, Rlang package was problem.
and I found that problem appears in case of package installation has stopped (in my case).
To solve problem.
- 1, Clear that Locked directory mentioned from console.
in your case, C:\Users\hermesr\Documents\R\win-library\3.6/00LOCK should be removed.
my case was Rlang and it still exists even problem has solved. 
.
-
2, Clear R workspace, it includes re-start R ( Rstudio )
-
3, install problematic packages independently first, In your case. it will be isoband package.
-
Last, it's time to install original package again.
install.package('ggplot2')
in these steps, you might have to repeat their step and as @technocrat saids, run rstudio as admin mode will be helpful. it can be achieved like this figure with right-click it. ( sorry for language, but I believe you can understand )

Good luck.
