[R] multiple graphs

[Daniele Amberti]

Does anyone have a simple explanation and example on how to add histograms or barcharts to an other graph like in the example at the R-graph gallery:

http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=109

looking at the code I'not undertand very well how to add graphs in arbitrary/clever position with an adequate scale.

If somebody have a simplier example with explanations it will be highly appreciate.

Best
Daniele
