Hi,
You can use rbind(). E.g.,
id<-rep(1:10,each=10)
x<-rnorm(100)
y<-rnorm(100)
d<-data.frame(id,x,y)
rm(id,x,y)
newdata<-data.frame()
for(i in 1:10){
newdata<-rbind(newdata,split(d,d$id)[[i]])
print(newdata)
}
The resulting data.frame "newdata" has rbind-ed all split elements of d (in

It's perfectly OK to develop regression models that predict wing data

You want array not list, as in
levelplot(array(rnorm(400,rep(1:4,each=100)),c(10,10,4)))
abind::abind is useful sometimes for binding preexisting matrices to
arrays.
