[R] Re trieving data frames from a for loop

[jebyrnes]

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.
