R help - Dec 2010 - Font family not found in Windows font database

Dear R Gurus,

I have a fairly simple problem, but I haven't been able to find the answer
on 'the google' or in the r-help archives.

I am generating plots on both Windows and OS X where I need to guarantee that
the font used is Arial. In my plot command I specify
'fontfamily="Arial"'. The problem is that on Windows I'm
getting the following warning:
Warning message:
In grid.Call.graphics("L_text", as.graphicsAnnot(x$label), x$x,  :
  Font family not found in Windows font database

Here is my plot call. I have not included supporting code, as I don't
believe it's necessary:
graph<-barchart(3.7,xlim=c(0,10),main="",xlab="",
	aspect=.1,
	col=rgb(21,101,112,maxColorValue=255),scales=list(x=list(tick.number=10,tck=c(1,0),fontfamily="Arial",fontsize=10)),
	panel=scorePnl,par.settings=theme.novpadding,lowCut=pgrLowCut,highCut=pgrHighCut)

In my research I've found that the default for Windows is Arial anyway, but
I should be able to specify the font without a warning. I further checked the
available fonts in the windows font database by using 'windowsFonts()'
and found an entry for 'TT Arial', however, specifying 'TT
Arial' produces the same error.

Any help is appreciated.

If you want to be sure of getting Arial, you could specify an explicit 
Windows Font mapping, for example, ...

windowsFonts(Arial=windowsFont("TT Arial"))
barchart(1, scales=list(x=list(fontfamily="Arial")))
