[Ipmpack-users] Help with IPMpack

[Eelke Jongejans]

Dear Iván,

Depending on how variable the number of leaves of juveniles, you either 
would want to include the number of leaves of juveniles as a continuous 
state variable (but IPMpack does not include the possibility yet to have 
more than 1 continuous state variable), or have the number of juvenile 
leaves as 1 or more discrete stages next to the continuous state 
variable palm height. Please have a look at functions like 
makeDiscreteTrans for examples.

best wishes,
Eelke
