I started the graphics device with X11(). When I tried to plot a tree object
with

plot (tree) 

It gives me the error message:

Error in plot.window(xlim, ylim, log, asp, ...) : invalid xlim

I was looking in the manual under "plot", "plot.window", etc. but I didn't
really get the resolution of my problem.....
What's the problem?

I still didn' get any answer to  this request, maybe it got lost...
It is a serious problem. Could it be a problem of my older release? Should I
update to R.0.90 ? I wanted not to have to compile it my self and there are
no binaries for SuSE 6.0  for this version.  

I have seen this before but it has always been some silly aspect of the
data I was trying to plot.  Is there any data at all (NAs).  For example:

y<-x<-c(0,1)
plot(x,y)

Produces a simple plot as expected but making all x's NA:

x<-c(NA,NA)
plot(x,y)

Error in plot.window(xlim, ylim, log, asp, ...) : invalid xlim

gives the error message you get.  Is it possible that the Linux and
Windows version set-ups are leading to different vectors for tree to
handle?

I am still using 0.63.3 under RH5.2 which is rock stable so I don't want
to upgrade 'cos there aren't any rpms for later R's under RH5.2!  Very
lazy really!
