Hi everyone~ I figured I would share this with everyone as we had somewhat of a difficult time figuring it out, and there didn't seem to be any documentation to that effect. We have marrayRaw objects in which multiple types of controls were defined, i.e. Control spots: There are 5 types of controls : Buffer Empty Fail N Real Empty 418 174 1164 7268 384 The data plotted fine, but I wanted a way to highlight more than just one type of control. The following commands seem to do exactly that: >highlight1.func <- maText(subset=maControls(name.raw)=="Buffer",labels="*",col="blue") >highlight2.func <- maText(subset=maControls(name.raw)=="Empty",labels="x",col="red") >highlight3.func <- maText(subset=maControls(name.raw)=="Fail",labels="@",col="green") >highlight4.func <- maText(subset=maControls(name.raw)=="Real Empty",labels="^",col="purple") >highlight.controls <- function(x,y) { +highlight1.func(x,y) +highlight2.func(x,y) +highlight3.func(x,y) +highlight4.func(x,y) +} >maPlot(name.raw,text.func=highlight.controls,lines.func=NULL,legend.f un c=NULL) Anyway, I hope this helps out someone along the way.
