Dear all,
I have a S4 object (HTCexp from HITC package), composed of one big matrix, and
two genomicRanges objects, A and B which describe the matrix raws and columns.
I thinking about a way to decrease the memory size of this object.
I also have methods to get/set the matrix and the two GRanges, namely
intdata(), x_intervals(), y_intervals().
In case of symetric matrix, the two GRanges can be the same, so I was
interested in simply creating in this case, a pointer from B to A. How can I do
it in R please ??
Second, I'm wondering if it exists other matrix-like object optimized for big
matrix (5000 x 5000). I quicky saw the Matrix object from the CRAN, useful for
sparse matrix.
Any suggestion would be appreciated !
Thank you
Regards
Nicolas
