[Ipmpack-users] IPMpack v1.5

[Eelke Jongejans]

Dear IPMpack-users,

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'.

best wishes,
Eelke

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 /Pmatrix/ (previously /Tmatrix/) as suggested by a 
reviewer. The makeFecObj and similar functions now have a /Formula/ slot 
in which the regression formula (e.g. nPups~size) can be entered.)
