Hi,

I have a similar query (how to compare 2 datasets), but my dataset is a bit
different.
I want to compare each data in dataset 1 to data in dataset 2 and get the
data which is common to both datasets.

For example;

I have a a file (named mysample).

V1      V2
YBL064C YBR067C
YBL064C YBR204C
YBL064C YDR368W
YBL064C YJL067W
YBL064C YPR160W
YBR053C YGL089C
YBR053C YHR113W
YBR053C YNL328C

And I have another file (myref) as follows

V1      V2
YBL064C YBR067C
YBL064C YBR204C
YBL064C YDR368W


When I try to intersect the two files, I received NULL data frames.

> intersect(myref,mysample)
NULL data frame with 0 rows

What I am hoping to get out of intersect for the above files are

YBL064C YBR067C
YBL064C YBR204C
YBL064C YDR368W

Are there any R functions that can achieve what I want to do?
Or should I merge the data which is currently in 2 columns into single
column and use intersect again?

Thanks for any feedbacks!
