mynonneg

The definition of "too many steps". Default value is $3$
(times $10$ times the matrix height).

This is the function <code><a rd-options="" href="/link/lsqnonneg?package=admixturegraph&version=1.0.2" data-mini-rdoc="admixturegraph::lsqnonneg">lsqnonneg</a></code> from the package <code>pracma</code>, 
I just changed <code><a rd-options="" href="/link/qr.solve?package=admixturegraph&version=1.0.2" data-mini-rdoc="admixturegraph::qr.solve">qr.solve</a></code> into using Moore-Penrose inverse instead
(<code><a rd-options="" href="/link/ginv?package=admixturegraph&version=1.0.2" data-mini-rdoc="admixturegraph::ginv">ginv</a></code> from <code>MASS</code>) as <code><a rd-options="" href="/link/qr.solve?package=admixturegraph&version=1.0.2" data-mini-rdoc="admixturegraph::qr.solve">qr.solve</a></code> crashes for
some singular inputs. Now it won't crash but it's sometimes running for very long
time (forever?), presumably with those problematic inputs. After too many steps
the function halts and lies that the fit was terrible. I don't think this will
cause problems.


Implements tools for building and visualising admixture graphs
and for extracting equations from them. These equations can be compared to f-
statistics obtained from data to test the consistency of a graph against data --
for example by comparing the sign of f_4-statistics with the signs predicted by
the graph -- and graph parameters (edge lengths and admixture proportions) can
be fitted to observed statistics.
