Hello,

If I make a plot, say something simple like

plot( runif(100) )

then the origin (0,0) is not at the bottom-left corner of the box
surrounding the plot. The axis limits are "padded" slightly. This is
ordinarily a good feature, because it makes plots look better. But now I
would like to make a plot with the origin exactly on the bottom left.
Through trial and error, I have discovered that this padding is
approximately 3.8% of the axis length. That is,

plot( runif(100), ylim=c(.038,1), xlim=c(3.8,100))

gives the desired result. However, this seems like a rather inelegant hack.
Is there a "correct" way to do this?

Thank you!
Enrico
