http://stackoverflow.com/questions/17499013/how-do-i-make-a-list-of-data-frames
How do I make a list of data frames and how do I access each of those data frames from the list? I can't find a simple example of this anywhere.
SO is telling me my post is too short, so I'll get the ball rolling by making a few data frames to be put in a list.
d1<-data.frame(y1<-c(1,2,3),y2<-c(4,5,6)) d2<-data.frame(y1<-c(3,2,1),y2<-c(6,5,4))
