I am very much an R novice so I am guessing this question is rather stupid/simple...

I have two vectors that represent two samples.
I would like to plot each of them (different colors) against the uniform CDF (something like a Q-Q plot).

To be precise, I would like something very similar to plot #7 [here](http://onlinestatbook.com/2/advanced_graphs/q-q_plots.html) (could not find what was used to draw that plot...). Figure 7 is displayed below:

only with multiple samples and some flexibility with changing the axis labels, colors and such.

Could you please point at a good direction?
