library(ggplot2)
Error: package or namespace load failed for ‘ggplot2’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘munsell’
Have you tried installing the munsell library?
Thank you very much, Prubin. Munsell library installation resolved the issue.
