Derar Rxperts,
I have a strange situation.. I see curly brackets around "strip.levels" in
multipanel strips while using lattice::xyplot. .How do I get rid of the
curly brackets? For some reason, I am not able to reproduce the problem
using an example below...
Any suggestions are highly welcome!
Thanks,
Santosh
q <-
data.frame(G=rep(paste("G",1:3,sep=""),each=50),D=rep(paste("D",1:5,sep=""),each=30),a=rep(1:15,each=10),t=rep(seq(10),15),b=round(runif(150,10,20)))
q$grp <- paste(q$D,q$a,sep=":")
q$grp <- ordered(q$grp, levels=unique(q$grp))
q$dcol <- unlist(sapply(q$D,function(x)
switch(x,"D1"="orange","D2"="blue","D3"="red", "D4"="seagreen",
"D5"="black")))
