[R] Graphical output: dials and meters for a dashboard?

[Parker Jones]

Hello,

I'm new to R and am evaluating it to see whether it would be an appropriate tool to create a "dashboard" (a graphical statistical summary page).  Could someone tell me if it is possible to display data as dials or meters. e.g. the four dials here: http://www.pentaho.com/images/snap_dashboard_1.png

Browsing the site hasn't revealed anything yet.

Thanks for any suggestions,
PJ
