Uses clonality object, and environmental transition objects to construct a matrix defining probabilities for transitions between sizes due to clonal reporudction given both a continuous state (e.g. size) and environmental state, as well as a discrete stage if necessary. Currently only pre-census clonal reproduction can be handled. NOTE - old createCompoundCmatrix is being deprecated; use makeCompoundCmatrix instead.

|
nEnvClass |
numeric, number of environmental classes, defaults to 2. |
nBigMatrix |
numeric, number of size bins in the P matrix, defaults to 50. |
minSize |
numeric, minimum size of the P matrix, defaults to -1. |
maxSize |
numeric, maximum size of the P matrix, defaults to 50. |
envMatrix |
envMatrix object defining transitions between environmental states for each size. |
clonalObj |
clonality object. |
integrateType |
integration type, defaults to "midpoint" (which uses probability density function); other option is "cumul" (which uses the cumulative density function). |
correction |
correction type, defaults to |
preCensus |
logical (TRUE or FALSE), indicating whether the fecundity object should represent an interval between pre-breeding or a post-breeding censusses. defaults to TRUE (pre-breeding census), meaning that all reproduction and offspring rates required for the F matrix are embedded in fecObj. Alternatively, an F matrix based on post-breeding census (preCensus=FALSE) requires additional survObj and growObj, to cover the survival and growth of the parents until the reproduction event. |
survObj |
suvival object, describing the survival of parents from a census until the reproduction event starts (at some point during the inter-census time step. |
growObj |
growth object, describing the growth of parents that survive until the reproduction event starts. Warning: this growth object is still ignored in makeIPMFmatrix in the current version of IPMpack. It will become functional in coming versions. |
offspringObj |
growth object, describing the size of offspring (this process may alternatively appear in fecObj). |
an object of class IPMmatrix with dimensions nBigMatrix*nEnvClass, or if discrete transitions exist (nBigMatrix+nDisc)*nEnvClass
