Dear all,

I would like to make a scatter plot using "plot" function.  I have two 
sample 1c and 2c, the 1st and 3rd are the ID of each gene, the 2nd and 
3rd are the values.  But as you can see some genes are not in the same 
row, i.e: ENSMUSG00000001020 is in the 4th row in sample 2c and 7th row 
of the sample 1c.  But I have nearly 1000 genes, I can not edit the data 
manually to fit the "plot" function.

Does "Plot" can automatically recognize every gene in different row of 
samples? If I simply do "plot(2c,1c)", then I guess the dot about gene 
ENSMUSG00000001020 would be (0.122112211, 0.655010678 ) instead of 
(0.122112211, 0.15301479).

Can someone give me some hint?

With many thanks in advance!

Best wishes,
Wei
