Data Smoothing with Splines

I have a couple of visuals I want to use from R, but when I try to load this visual (and others) I am having issues trying to install the needed libraries  I uninstalled the current version or R (3.5.1) and installed the version given in most all the visualizations in this section (3.3.1), but still I can't load most of the required libraries.

You say the visualization you require requires 

Required R packages:

graphins, spline, scales

I can load scales, spline is not available for 3.3.1, but I installed splines2 which was available and I assume is similar enough thet I can make it work.  However I don't know what to do with graphins.  I can't find anything similar at CRAN, CRAN2, R-Forge, or rforge.net.  Is there another repository that I should be using?

Thanks!
