qr: QR decomposition of an HDF5Matrix

In BigDataStatMeth: Title: Scalable Statistical Computing with HDF5-Backed Matrices

QR decomposition of an HDF5Matrix

Description

Overrides base::qr() to dispatch on HDF5Matrix objects. For plain R matrices the call is forwarded to base::qr().

Usage

qr(x, ...)

Arguments

x	An HDF5Matrix or a plain R matrix/vector.
...	Additional arguments passed to qr.HDF5Matrix() or ignored for qr.default().

Value

For HDF5Matrix: a named list with elements Q and R (both HDF5Matrix). For plain R objects: the result of base::qr().
