R help - May 2008 - axis and tick widths decoupled (especially in rugs!)

Hi!

(a complete newby, but will not give up easily!)

I was wondering if there is any way to decouple the axis and tick mark
widths? As I understand they are both controlled by the lwd setting, and
cannot be controlled independently? For example I might want to create major
and minor ticks, which I now know how to do by superimposing two axes with
different at settings, but what if I also wanted the major ticks to be
thicker? or a different colour?
You might find this nitpicking, but I am particularly concerned about rug(),
which passes to axis(), in that I cannot get a decent thick-lined rug,
without the horizontal line also becoming equally thick. 
Is there any way to do this without having to resort to segments?

Tnx!

I don't think so, other than rewriting the internal axis code.

Hi
This is an ad-hoc fix.. 
d<-rnorm(4)
plot(1:4,d)
g<-3;
rug((1:4),ticksize=-.03,lwd=g,side=1)
rug((1:4),ticksize=0,lwd=(g-1),side=1,col="white")

just drawing another white axis on top of the old one.. it looks ok :)
