Description

Function to extract samples from the output of an XDNUTS model.

Usage

xdextract(X, which = NULL, which_chains = NULL, collapse = FALSE)

Arguments

X

an object of class XDNUTS.

which

either a numerical vector indicating the index of the parameters of interest or a string

which = 'continuous'

for plotting the first d-k parameters.

which = 'discontinuous'

for plotting the last k parameters.

where both d and k are elements contained in the output of the function xdnuts.

which_chains

a vector of indices containing the chains to extract. By default, all chains are considered.

collapse
