I get the following error when I try to load ggplot2. I tried to uninstall scales and reinstall it but for some reason R can't find the package when I want to remove the package...
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
namespace ‘scales’ 0.2.5 is already loaded, but >= 0.3.0 is required
In addition: Warning message:
package ‘ggplot2’ was built under R version 3.2.3
Error: package or namespace load failed for ‘ggplot2’
update.packages(checkBuilt = TRUE).
