Hi,
 
what is the recommended way to vertically concatenate 2 data frames with
the same column names but different number of rows?
 
My problem is something along these lines:
 
df1 <- data.frame(var1=var1,var2=var2,var3=var3)  # nrow(df1)=1000
df2 <- data.frame(var1=var4,var2=var5,var3=var6)  # nrow(df2)=2000
 
I tried df <- c(df1,df2), no success. stack does not seem to be
appropriate either for my problem.
 
 
Thanks
 
Zava
