Hi R-users and R-experts:
Is it posible to make transparent graphics on R? I mean, one graphic with colors over another one but both visible with transparent options?
In general this is not possible, but ...
If you are prepared to work with grid graphics, and produce SVG output, and use a very experimental package, then take a look at the gridSVG package (http://www.stat.auckland.ac.nz/~paul/index.html). The package has a vignette with a very simple example of transparency and there are a couple more examples in some talk slides also linked off the page given above. The package has some serious deficiencies, but I have seen one reasonably complex real usage of it.
A general alpha transparency graphical parameter may be added to R in the near future, but even then this will not be respected by all output formats.
