[R] Changing chart border's color

[Rasmus Liland]

Right, adding a black border around a 
plot in R is meaningless.  

There is also another circular plot 
being created everytime FactoMineR::PCA 
runs.  

It might be (perhaps, idk) fruitful for 
you to look at the contents of res.pca 
using str and create the PCA plot 
yourself using ggplot2 ...  or maybe 
plotly inside a shiny app ....
