[R] font size in legend

[herodote@oreka.com]

Hy all

I use barplot to draw frequencies by dates.

On the x axis it shows only 1 date for 2 bars, i've understand why, because R cant put so much date on the same axis, it will get out of the graph.

that's why i tought about reducing the size of the font used to stamp the x axis.

anyone knows the right way? i've tryed par(cin) and barplot(cin=3) but it says i cannot do it at this level...

thks you all.
