Distribute points along lines

Hi!

Is there any way to distribute a set of random or regularly-spaced
points along a line imported from a shape file into a
SpatialLinesDataFrame? I've been searching, but could not find it.
Should I use coordinates() to get the vertex, then calculate the a&b
parameters for each line and distribute the points? Or is it there
something already done?

Thanks,

Agus
