modifying color and shape points on dotplot

[ebellin@speakeasy.net]

To the group,

I would like to run a dotplot where the variables are group,days,color.  A 
single group may have multiple rows in the original dataset.

Attempts to do this in splus 6.0

has resulted in error messages

dotplot(group~days,col=color)

Too many values for parameter col; some ignored>

I am trying to get certain events to be flagged with different color within 
group.  Once this is accomplished, I will want to do the same with different 
shapes.

I have the hmisc library and design library loaded.

Any advice would be appreciated.

Sincerely,
Eran Bellin
