[R] Could not find function even though I have all necessary packages

[Michael Artz]

Thanks.  SessionInfo() did not show it.

This is the error when I try library(caret)


> library(caret)
Loading required package: ggplot2
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck
= vI[[j]]) :
  there is no package called ‘munsell’
Error: package ‘ggplot2’ could not be loaded

I tried installing.packages("ggplot2") and then I ran
library(ggplot2) and it gave me error

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck
= vI[[j]]) :
  there is no package called ‘munsell’
Error: package or namespace load failed for ‘ggplot2’
