[R] question of merging two dataframes

[freezhu8]

Suppose I have two data frames A and B
A has three variables and B also has three variables.
I would like to merge these two database but the requirement to merge
is that the value of the second column in database A is less than the
value of the second column in database B. Is there a R code to do
this? Thanks

Dataframe A:   V1a   V2a   V3a
                   1  2      3         5
                   2  3      4         6
                   3
Dataframe B:   V1b  V2b V3b
                  1  2       5      9
                  2  9       2      7
Dataframe C should be:   V1a   V2a  V3a  V1b   V2b   V3b
                                 1  2        3      5      2       5       9
