for.

Dear Sohail,
Probably there are better
ways of doing it - one possibility is:
plot(df1$X, df1$Y,
type='n')
for (i in unique(df1$Chr))
points(df1$X[df1$Chr==i],df1$Y[df1$Chr==i],col=i)
Best
wishes,
Mario

Dear S-plus users,

I want to create a
scatter plot of X,Y, "color coded" based on the column Chr. I.E.
chr1=red,chr2=green, chr3=yellow, so on.......
Can this be done in
S-PLUS?? I would appreciate your help.
Thanks.
