The function returns internal information about the simulation of a random field
GetRegisterInfo(register=0, ignore.active = FALSE, max.elements=10^6) GetModelInfo(register=0)

-2, -1, 0:9;
place where intermediate calculations are stored;
the numbers 0:9 are aliases for 10 internal registers, see also
GaussRF |
ignore.active |
logical. If FALSE and the register has
non-active flag (because of an error or it is deleted) then a list
is returned that contains only the element active=FALSE.
Otherwise, the full list is always returned.
|
max.elements |
integer; since GetRegisterInfo
might be a dump of simulation that needs a huge amount of
memory and since all entries are copied, the maximal amount
of available memory might be easily exceeded. Therefore,
only the size of the critical parts are returned and not the
vector or matrix itself, if the number of elements exceeds
max.elements.

GetRegisterInfo(register, ignore.active=TRUE) is
useful for debugging and specialists' need to control
the algorithm, see the examples in RFparameters
and GaussRF.
If RFparameters()$Storage=FALSE then values of
the internal registers are not kept if GaussRF or
DoSimulateRF has been called.
Hence GetRegisterInfo cannot
provide any information.
GetModelInfo returns the partial information on the internal
model structure. It allows for register=-1 returning the
model structure for the last use of CovarianceFct
or Variogram or similar commands.
register=-2 is for internal use only.
List of internal information is returned.
Put Storing=TRUE, see RFparameters
if you like to have more
internal information in case of an expected failure of an initialisation of
a random field simulation.

# lets regard at a non-initialised register first:
DeleteAllRegisters()
str(GetRegisterInfo(0))
# now, a register that has successfully initialised
try(GaussRF(1:4, grid=TRUE, model="exp", param=c(1,2,3,4), Storing=TRUE))
str(GetRegisterInfo(0))
# finally, a register that could not be successfully initialised
try(GaussRF(runif(4), grid=FALSE, model="exp", param=c(1,2,3,4),
me="ci", Storing=TRUE))
str(GetRegisterInfo(0, TRUE))
