[R] Lattice plot within a "for" loop does not happen?

I am trying to do a series of xyplots plots, using a "for" loop to substitute the appropriate variables for each plot. The basic command works fine by itself and produces a nice plot:

> i<-3
> trellis.device(theme="col.whitebg")
> xyplot(as.formula(paste(tmp00[2*i], "~ ", tmp00[(2*i)-1],

+                             "|Blastomere+Phenotype", sep="")),
+         data=tmp1,
+         panel=function(x,y,...){
+           panel.xyplot(jitter(x), jitter(y), pch=16, col="red")
+           if (max(x, na.rm=T)!=0.0) panel.xyplot(x, y, type="r",  
+        })


BUT, when I stick this in a loop, I get a bunch of blank graphics devices. This happens even if the loop only executes once. I could just go through and do these one by one, but I was curious if I was overlooking something obvious. Thank you for any advice.
