[BioC] Combine two data frames with different columns

[Daniel Brewer]

I would like to join two dataframes that have the majority of columns in
common but some different.  Let me give you an example:

Dataframe 1

ID	COL1	COL2	COL3
1	a	a	a	
2	b	b	b
3	c	c	c

Dataframe 2

ID	COL1	COL2	COL4
4	a	a	d	
5	b	b	d

And the joined dataframe I would like is:

ID	COL1	COL2	COL3	COL4
1	a	a	a	NA
2	b	b	b	NA
3	c	c	c	NA
4	a	a	NA	d	
5	b	b	NA	d

Any ideas?

Dan
