[BioC] Questions in GOvis.pdf - a GOStats vignette

[Srinivas Iyyer]

Dear group, 

In GOvis.pdf , vignette for GOstats on page 7, code
snippet for representing a pie-chart there are some
objects that are difficult to guess their origin. I
request if any one can suggest how they can be
created. 

1. "gCClo"

This object was first mentioned on page 8:
plotPieChart(gCClo, ctmat)


I am not sure what is gCClo. 

Could any one help me understand here. 

Thanks
