Dear IPMpack-users,<br>
<br>
v1.5 is now online. This version has some new features and fixes
based on the IPM summer course in Rostock a few weeks ago. In order
to run IPMpack v1.5 correctly, PLEASE MAKE SURE YOU HAVE INSTALLED
THE 'Matrix' PACKAGE VERSION 1.0-9. Otherwise you might run into
errors concerning the superclass 'mMatrix'.<br>
<br>
best wishes,<br>
Eelke<br>

IPMpack v1.5 has new sensitivity functions (for life expectancy, R0,
etc) and createIntegerPmatrix lets you build population transition
models with integer stages only, based on various vital rate models.
We've made further improvements to amongst others the functions
makeFecObj, makeDiscreteTrans and elas. The survival and growth
matrix is now called <i>Pmatrix</i> (previously <i>Tmatrix</i>) as
suggested by a reviewer. The makeFecObj and similar functions now
have a <i>Formula</i> slot in which the regression formula (e.g.
nPups~size) can be entered.)<br>
