"Nice" graphs for PPT: Alternative to "rvg" package

I am trying to create nice graphs (preferably in base-r, but ggplot2 would also be okay) for a PowerPoint presentation in R. By "nice", I mean high resolution and seemingly well embedded.
I am trying to install the "rvg" package for the same and use it in conjunction with "officer" (which has been installed successfully), but I get the following error message:

<stdin>:1:10: fatal error: 'ft2build.h' file not found
#include <ft2build.h>
         ^
1 error generated.
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because freetype2 was not found. Try installing:
 * deb: libfontconfig1-dev (Debian, Ubuntu, etc)
 * rpm: fontconfig-devel (Fedora, EPEL)
 * csw: fontconfig_dev (Solaris)
 * brew: freetype (OSX)
If freetype2 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a freetype2.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

Consequently, even though I have given permission for R to install dependencies (such as gdtools), I cannot use this package. Is there a way I can correct the error? Or can I use another package? I'm using R version 3.3 on a Mac (OS X Yosemite).

Update: I cannot download rvg at all, despite the suggestions below, is there a good alternative?

R 3.3 is very old and likely to give you a lot of headache even if you solve this particular problem. Current version is 3.6.3, so you should consider upgrading and then trying again.

That being said, you do have a hint in your error output that suggests a way to solve a problem - install freetype with brew. This may or may not solve the actualy problem you are having, so give it a try.

Unfortunately, cannot go beyond 3.3 on Yosemite. Thanks for your advice though, I'll install freetype.
