R help - Apr 2012 - problem with mean.labels=TRUE in plotmeans command (gplots)

I have been using plotmeans() from the gplots package to create graphs, and I
would like to display the mean values instead of dots on the graphs. I tried
adding mean.labels=TRUE to the command, but the graph displays the dot with the
mean value overwritten. Has anyone else encountered this problem? I wondered if
this might be a bug, or whether there was some way of working around it.

I have put an example below. I am using R version 2.15.0 on a 2008 macbook
(using mac os x 10.7.3).

x<-1:9
y<-c(rep("a", 3), rep("b", 3), rep("c", 3))
frame<-data.frame(x, y)
plotmeans(x~y, data=frame, mean.labels=TRUE, connect=FALSE)
