block_size

It determines the value of <code>block.size</code> such that a matrix of doubles of
size <code>n</code> x <code>block.size</code> takes less memory than
<code>getOption("bigstatsr.block.sizeGB")</code> GigaBytes (default is 1GB).

Easy-to-use, efficient, flexible and scalable statistical tools.
Package bigstatsr provides and uses Filebacked Big Matrices via memory-mapping.
It provides for instance matrix operations, Principal Component Analysis,
sparse linear supervised models, utility functions and more
