Dear all r-users,

Suppose I have two data frame:

A
1
3
4
5
2

and

B
5
6
3
5

Now I want combine this two data frames without losing any value from either
data frame. More precisely I want to see

 A    B
1   5
3   6
4   3
5   5
2   NA

I tried with cbind function but failed, as it only works when two data
frames have equal number of rows. Can anyone suggest me any code that can be
used for any data set?

Thanks and regards
