Hi,

I've lost my mind on it... I have to scatterplot two vectors, grouped by a third variable, with two different dimensions according to whether each cell line in the plot is sensitive or resistant to a given drug, and with a different color for each of 9 tissues of origin.


Here's what I've done:

>obj<-xyplot(EGFR~EPHA2,data=Dataset,groups=interaction(Sens,Tissue),cex=c(1,3),pch=19)
>        update(obj, par.settings =
+        custom.theme(symbol = brewer.pal(9, "Paired"),
+        fill = brewer.pal(9, "Paired")))
>

Here are the data:
