Hello,
I have indicators for the present of absent of a snps in columns and the
categorey (case control column). I would like to extract ONLY the tables and
the indices (SNPS) that give me 2 x 3 tables. Some gives 2x 2 tables when
one of the allelle is missing. The data look like the matrix snpmat below:
so the first snp should give me the following table: (aa=0, Aa=1 and AA=2)
aa Aa AA
case 2 3 0
control 2 2 0
So I should not use this one or if I am using it, then I need to see 0 0 in
to AA column which I don't see when I use the table command in R.
snpmat
category SNP1 SNP2 SNP3 .... SNPN
case 1 0 2 1
case 0 1 1 2
case 1 2 2 0
control 0 1 0 1
control 1 2 1 2
control 0 0 0 0
case 1 0 2 2
case 0 1 2 1
control 1 0 0 1

Thanks,
Jim.
