Hi, I need to deal with very large matrices and I was thinking of using HDF5-based data models. However, from the documentation and examples that I have been looking at, I'm not quite sure how to do this.
My use case is as follows. I want to build a very large matrix one column at a time, and I need to write columns directly to disk since I would otherwise run out of memory. I need a format that, afterwards, will allow me to extract subsets of rows or columns and rank them. The subsets will be small enough to be loaded in memory. Can I achieve this with current HDF5 support in R? Any help greatly appreciated. than you, Francesco _______________________________________________ Bioc-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/bioc-devel
