rstan_options(...)opt = val set
option opt to value val. Arguments of the
form opt set the function to return option opt's value.
Each argument must be a character string.list for existing options and NA for non-existent options.
When only one option is specified, its old value is returned.plot_rhat_breaks: The cut off points for Rhat for which we
would indicate using a different color. This is a numeric vector,
defaulting to c(1.1, 1.2, 1.5, 2).
The value for this option will be sorted in ascending order,
so for example plot_rhat_breaks = c(1.2, 1.5) is equivalent to
plot_rhat_breaks = c(1.5, 1.2).
plot_rhat_cols: A vector of the same length as
plot_rhat_breaks that indicates the colors for the
breaks.
plot_rhat_nan_col: The color for Rhat when it is Inf or NaN.
plot_rhat_large_col: The color for Rhat when it is larger than
the largest value of plot_rhat_breaks.
rstan_alert_col: The color used in method plot
of S4 class rstan_chain_cols: The colors used in methods plot
and traceplot of S4 class rstan_warmup_bg_col: The background color for
the warmup area in the traceplots.
boost_lib: The path for the Boost C++ library used
to compile Stan models. This option is valid
for the whole R session if not changed again.
eigen_lib: The path for the Eigen C++ library used
to compile Stan models. This option is valid
for the whole R session if not changed again.
auto_write: A logical scalar (defaulting to FALSE) that
controls whether a compiled instance of a stanmodel-class
is written to the hard disk in the same directory as the .stan
program.
