R help - Feb 2011 - dotchart {graphics} 2.11.1 vs. 2.12.1

I have a factor vector of subject races (Asian, Black, Hispanic, White; n=30)
that I want to plot with a Cleveland dotplot or dotchart.

I tried the following in R2.12.1 :
> dotchart(table(school$Race))
Error in plot.xy(xy.coords(x, y), type = type, ...) : invalid plot type
 
Using the same data set in R2.11.1 the operation succeeded (I tried several
variations to be sure):
> dotchart(table(school$Race))
> race2<-table(school$Race)
> dotchart(race2)
> dotchart(race2, pch=17,col="red")
Each of these worked in 2.11.1 but not in 2.12.1;  What changed in the
{graphics} package to alter this and is there a work-around?

Hi,

Its a bit messy, but here is a quick work around:

dotchart(as.matrix(table(infert$education))[,1])

I wonder if this has something to do with the addition of table
methods for points() and lines().  I'll post back if I find anything
more out.


Cheers,

Josh
