Have you tried making a list of data frames instead? So
data.list<-list()
for (i in 1:20) {
g<-sample(rep(LETTERS[1:2],each=10))
#make a name
a.name<-paste("combination",i,sep="")
#add it to the list of data frames
data.list[[a.name]]<-data.frame(tab,g)
}
This should be easier to iterate over later.
