eicm.options | R Documentation |
Construct a EICM options object to inform the fitting engine. There is usually no need to use this function directly.
eicm.options(...)
... |
a named list of options. See details. |
Possible options are currently: mask
and offset
. Both are lists having the same structure of an eicm.matrix
object:
Binary matrices defining which coefficients are to be estimated in model fitting OR a scalar, constant for all coefficients. 0 or FALSE exclude the given term from estimation, i.e., fixes it at 0.
environmental coefficient mask
species interaction mask
Numeric matrices defining constant terms, to be fixed and not estimated
environmental coefficient offset
species interaction offset
When an offset for a term is nonzero, the respective mask element will be automatically zeroed (so it is not estimated).
A eicm.options
object with options for model fitting, currently a model mask and model offsets.
