An object of the same class as x
, but in general smaller. See the
“Methods” section below for details.
signature(x = "SampleSetup")
returns the last parts of set up
samples. The last n
indices of each of the last k
set up
samples are kept.
signature(x = "SimControl")
currently returns the object itself.
signature(x = "SimResults")
returns the last parts of
simulation results. The method of tail
for the
data.frame
in slot values
is thereby called.
signature(x = "Strata")
returns the last parts of strata
information. The method of tail
for the vector in
slot values
is thereby called and the slots split
and
size
are adapted accordingly.
signature(x = "VirtualContControl")
currently returns the object itself.
signature(x = "VirtualDataControl")
currently returns the object itself.
signature(x = "VirtualNAControl")
currently returns the object itself.
signature(x = "VirtualSampleControl")
currently returns the object itself.
