R help - Nov 2003 - problems with xlab

Dear R-list members,

I'm using the 'effects' package to plot a graph with fixed values.
For some reason, I cannot change the label for the 'x' axis using
'xlab=""'. The usual commands work for the y axis and for the
main title. My last attempt used the following syntax:

model.effects<-(all.effects(model.1))
plot (model.effects, main="Figure
1",xlab="Year",ylab="Change")

The resulting graph has the default label for the x axis instead of
'Year'. The main title and the label for 'y' are as expected.
 
Anyone knows what may be happening?

All the Best,

                                           Celso

I'm afraid that you've found a bug in plot.effect(): I omitted
specifying
the xlab argument to xyplot() in one of the six cases that plot.effect() 
distinguishes. The fix is simple, and I'll shortly upload a new version of 
the package with it, but in the meantime, I'll send you (privately) the 
fixed version of plot.effect().

I apologize for the problem,
  John
