Hi, I have a quick question here. Lets say he has three data frames and he
needs to combine those three data frame using merge. Can we simply use
merge to join three data frames ? I remember I had some problem using merge
for more than two dataframes.
Thanks.

Hi,
This should be fairly easy by using base R graphics.
Lets suppose your first data is represented by (x1,y1) and second data is

You can use the following command.
plot(x1,y1,type="l")
points(x2,y2)
Hope it helps.
