[R] using minor tickmarks with xYplot

2005-11-28 Thread Viet Nguyen
Hi all,

I'm trying to make a plot with the function xYplot from package Hmisc in 
R.  I would like to have minor tick-marks on the axis.  This should be a 
common simple feature to have but I don't seem to find any discussion on 
the topic.

Following is one of the things I tried and the error returned:

xYplot(y~x,data.frame(x=seq(1,10),y=runif(10)),minor.ticks=c(3.5,5.5))
Error in panel(x = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), y = 
c(0.88172451662831,  :
object gfun not found

It's important that I use xYplot and not plot so function 
minor.tick() is not useful.

Anything I can try?  Thanks in advance for your help.

This is a bug in panel.xYplot.  Charles Thomas Dupont will fix it and 
give you the URL to our CVS area containing the new version, then you 
can do source('http://') to override panel.xYplot until Thomas puts 
out a new version of Hmisc. -Frank
