get.models  R Documentation 
Generate or extract a list of fitted model objects from a
"model.selection"
table, optionally using parallel computation in a
cluster.

The argument subset
must be explicitely provided. This is to assure that
a potentially long list of models is not fitted unintentionally. To evaluate all
models, set subset
to NA
or TRUE
.
If subset
is a character vector, it is interpreted as names of rows to be
selected.
list
of fitted model objects.
Alternatively, getCall
and eval
can be used to compute a model out of the
"model.selection"
table (e.g. eval(getCall(<model.selection>, i))
, where
i
is the model index or name).
Using get.models
following dredge
is not efficient as the requested models
have to be fitted again. If the number of generated models is reasonable, consider using
lapply(dredge(..., evaluate = FALSE), eval)
, which generates a list of all model
calls and evaluates them into a list of model objects. This avoids fitting the
models twice.
pget.models
is still available, but is deprecated.
