Packages won't run after installing in Rstudio - r

Question

I have installed the packages psych and ggplot2 in Rstudio. However I am not able to load these packages because I keep getting these error messages:
library("psych", lib.loc="~/R/win-library/3.3")
Error in runHook(".onLoad", env, package.lib, package) :
cannot open file 'C:/Users/Ernstsen/Documents/R/win-library/3.3/mnormt/R/mnormt.rdb': No such file or directory
Error: package or namespace load failed for ‘psych’
> library("ggplot2", lib.loc="~/R/win-library/3.3")
Error in library.dynam(lib, package, package.lib) :
DLL ‘colorspace’ not found: maybe not installed for this architecture?
Error: package or namespace load failed for ‘ggplot2’
And this error:
package ‘ggplot2’ successfully unpacked and MD5 sums checked
The downloaded binary packages are in
C:\Users\Ernstsen\AppData\Local\Temp\RtmpoTRXOY\downloaded_packages
> library("ggplot2", lib.loc="~/R/win-library/3.3")
Error in library.dynam(lib, package, package.lib) :
DLL ‘colorspace’ not found: maybe not installed for this architecture?
Error: package or namespace load failed for ‘ggplot2’
I have tried installing Rcpp, reinstalling R and Rstudio, using install.packages('ggplot2', dependencies = TRUE) for both packages, I'm not sure what else I can do. This program was working fine on my older computer before it died.

There are several causes why this can happen, and on Windows there's the permissions issue if your R install directory was Administrator privileges and/or was under "C:\Program Files" or "C:\Program Files (x86)". Trying to install and maintain packages under those is a nightmare - constant permissions issues.
Moving your R package directory instead to your ~ is a good idea, esp. if you installed as Administrator, or use one of the more permissions-freakish licenses like Windows Business/Enterprise.
