R help - Mar 2008 - Rcmder Error

Hi Guys,

I am trying to show a plot of means with two groups. i.e.
> plotMeans(s$CON, s$GENERAL.STARTING.DEPT, s$Cat, error.bars="se")
and I get the error in Rcmdr:

ERROR:  need finite 'ylim' values

Pasting the code in R gets the following error:

x) : no non-missing arguments to min; returning Inf
Warning in max(x) : no non-missing arguments to max; returning -Inf
Error in plot.window(...) : need finite 'ylim' values

I'm not sure what's going on. I know in R 2.6 I ran the same code and 
had no problem. Any suggestions on what I can do to fix it?

Thanks,

-Max

That type of error often means a data problem, for example
dividing by standard deviation zero, or something similar.

Please look at your data values.  Do you have enough items at
each level of x that standard deviations can be calculated?

Dear Max,

As Rich Heiberger has suggested, it's difficult to diagnose the error
without the data, and it's especially curious that this previously worked (I
assume from your message with the same data) and doesn't now. 

Regards,
 John
