[Rd] Bug with tick marks on x-axis.

I have a dataset where we are trying to model the resistance of
horses' lungs. One of the covariates is the administered
pressure. This variable is a little odd in the sense that an increase
of pressure corresponds to a "more negative value" of the covariate. A
graph representing the change in resistance in function of the
pressure would be helpful for the biologist. But it should have the
x-axis (pressure) going from positive to negative pressure values to
correspond to an increase in pressure (this representation is clearer
to the biologists).
Now under Windows 95 and 98 with rw1011, I get a problem with the
tick marks of the x-axis. Here is a small example:
x <- (0:-4)*10
y <- rnorm(5)
plot(x,y,type="l") # ok
plot(x,y,type="l",xlim=c(0,-40)) # missing all except the last tick mark (-40)
I don't know if there is some way to get around this... it might be
easier to just use a previous version of R which does not contain that
Thank you for any suggestions,
