A generic wrapper around posterior::summarise_draws()
with
opinionated defaults. See fv_tidy_posterior()
for a more
opinionated wrapper with further cleaning and tidying
including linking to observed data, tidying parameter names,
and transforming parameters for interpretability.
Usage
fv_posterior(fit, probs = c(0.05, 0.2, 0.8, 0.95), digits = 3, ...)
Arguments
- fit
List of output as returned by
fv_sample()
.- probs
A vector of numeric probabilities to produce quantile summaries for. By default these are the 5%, 20%, 80%, and 95% quantiles which are also the minimum set required for plotting functions to work (such as
plot_cases()
,plot_rt()
, andplot_voc_frac()
).- digits
Numeric, defaults to 3. Number of digits to round summary statistics to.
- ...
Additional arguments that may be passed but will not be used.
