Hi All

I have a huge matrix m (10276 X 10276) dimension with same column name and
row names. (its a gene correlation matrix). I have another text file which
has 2700 names, basically locus ID of genes, which are also
rownames/colnames in m. Now I want to select all those columns from m whose
names match with the names in the text file and return ONLY those columns
and ALL the rows in a matrix format.
That is, the output should a matrix of dimension 10276 X 2700.

I have played around with subset and also tried all different methods like
reading the text file, converting to matrix and character and DF and tried
all possible ways I found on the web. The problem is that some of them work
on a smaller simulated dataset but says "Subscript out of bounds"  when I
try on the bigger matrix(m).

Please help.. :(

Thanks!
