"envelope"

."envelope"
. The function envelope
is generic. This is the method for
the class "envelope"
.
The argument Y
should be a simulation envelope (object of
class "envelope"
) produced by any of the methods for
envelope
.
If the argument fun
is given, it should be a summary function
that can be applied to the simulated point patterns that were
used to create Y
. Also, Y
should contain
these point patterns, so Y
should have been created by calling
envelope
with savepatterns=TRUE
. The envelope of
the summary function fun
for these point patterns
will be computed using the parameters specified in ...
.
If fun
is not given, then the new envelope will be computed
from the same set of simulated function values
that were used to compute Y
.
Also, Y
should contain these function values,
so Y
should have been created by calling
envelope
with savefuns=TRUE
. The envelope
will be computed using the parameters specified in ...
.
See envelope
for a full list of envelope parameters.
Frequently-used parameters include nrank
and nsim
(to change the
number of simulations used and the significance level of the
envelope), global
(to change from pointwise to global
envelopes) and VARIANCE
(to compute the envelopes from the sample
moments instead of the ranks).
