SPQR-class

Objects of class <code>"SPQR"</code> are typically the result of
  <code><a href="/link/spqr?package=Matrix&version=0.999375-20" rd-options="" data-mini-rdoc="Matrix::spqr">spqr</a></code>, one kind of sparse QR decompositions.<p></p><p>  Currently, <code><a href="/link/qr?package=Matrix&version=0.999375-20" rd-options="" data-mini-rdoc="Matrix::qr">qr</a>(<sparsematrix>)</sparsematrix></code> is more widely used and
  provides a different class, <code><links4class>sparseQR</links4class></code>.</p>
