R help - Dec 2015 - How to install pkg when "not found" ?

Using "Install Packages" from CRAN, in RStudio on Windows 7,
I downloaded (and supposedly installed)  ggplot2 package to here:

C:\Program Files\R\R-3.1.0\library\ggplot2_2.0.0\ggplot2


.... when I try this:
> require(ggplot2)
.... I get the following:
Loading required package: ggplot2
Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return =
TRUE,  :

  there is no package called 'ggplot2'


.... I also tried this:
> install.packages(ggplot2)
Error in install.packages : object 'ggplot2' not found

......


The above library has the usual things like MASS, stats, base, utils, graphics
and so on....
..... and if I do this:
> require(MASS)
.... I get this:
Loading required package: MASS

.... so that works....


..... Any idea what I'm doing wrong with ggplot2?
