[R] [BioC] comparing two tables

[tomkina]

Hello,

I have the similar task.  I have two tables and I need to get the third
table containing data from both of them with extra column with information
of what data from which table:

table1			
chr	pos	ref	alt
chr1	5	A	G
chr1	8	T	C
chr2	2	C	T

table2			
chr	pos	ref	alt
chr1	5	A	G
chr1	7	T	C
chr1	8	T	A

resulted table
chr	pos	ref	alt	info
chr1	5	A	G	1, 4
chr1	7	T	C	4
chr1	8	T	C	1
chr1	8	T	A	4

I need all 4 columns (chr, pos, ref and alt) to be compared. I didn't find
this function in Bioconductor. I am a beginner at R and would appreciate any
help.

Thanks,
Tamara
