object.summary()
browntree
object can be coerced to a data-frame
via as(object,"data.frame")
.coef(object,...)
sigma
:theta
:sigma..sq.matrix
:logLik(object,...)
update(object, ...)
object
is the browntree
object.
Additional arguments (in ...
) replace the corresponding arguments in the original call.
bootstrap(object, nboot = 200, seed = NULL, ...)
object
is the browntree
object.
nboot
is the number of bootstraps.
seed
allows one to fix the random seed (see simulate
below).
Additional arguments (in ...
) are passed to update
.
simulate(object, nsim = 1, seed = NULL, ...)
object
is the browntree
object, nsim
is the desired number of replicates, and seed
is (optionally) the random seed to use.
simulate
returns a list of data-frames, each comparable to the original data.
