Description Usage Arguments Details Value Note See Also Examples
The function returns information about an RMmodel, either internal information when used in simulations, for instance, or general information

Internally, the sub-models are represented in two different ways: ‘internal’ and ‘user’. The latter is very close to the model defined by the user. Most models have a leading internal model.

RFgetModelInfo
branches either into
RFgetModelInfo_register
or RFgetModelInfo_model
,
depending on the type of the first argument. The latter two are
usually not called by the user.
RFgetModelInfo
has three standard usages:
RFgetModelInfo()
returns internal information on the
last call of an RF
function.
RFgetModelInfo(RFfunction)
returns internal information on the
last call of RFfunction
.
RFgetModelInfo(RMmodel)
returns general information on
RMmodel
Whereas RFgetModelInfo()
can return detailed internal information,
RFgetModel
returns a model that can be re-used
by the user.
If RFgetModelInfo(model)
is called a list is returned with the
following elements:
trans.inv
: logical. Whether the model is translation
invariant (stationary)
isotropic
: logical. Whether the model is rotation
invariant (stationary)
NAs
: in case of an additive model it gives the number
of NAs in each submodel
minmax
: a data frame containing information on all
arguments set to NA
s
pmin
, pmax
: lower and upper endpoint of the
parameter values usually found in practice
type
: integer; recognized particularities of a parameter;
an explanation of the values is given after the table, if printed.
NAN
: the number of NAN
s found
min
, max
: mathematically valid lower and upper
endpoints of the parameter values
omin
, omax
: logical. If FALSE
the
respective mathematical endpoint is included
col
, row
: the dimension of the parameter.
If the parameter is a scalar then col = row = 1
. If it is a
vector then col = 1
.
bayes
: currently not used (always FALSE
)
Else a list of internal structure is returned.
Put Storing=TRUE
, see RFoptions
if you like to have more
internal information in case of failure of an initialisation of
a random field simulation.
