Package overview Overview of tidybayes.
`tidybayes-package`	Tidy Data and 'Geoms' for Bayesian Models
`tidybayes-models`	Models supported by tidybayes
Composing data for input to a model Transform tidy data frames into data lists appropriate for model types like Stan and JAGS
`compose_data()`	Compose data for input into a Bayesian model
`data_list()` `as_data_list()`	Data lists for input into Bayesian models
`n_prefix()`	Prefix function generator for composing dimension index columns
`x_at_y()`	Generate lookup vectors for composing nested indices
Extracting posteriors Get tidy draws of posterior distributions from objects (and helper functions for examining objects)
`get_variables()`	Get the names of the variables in a fitted Bayesian model
`recover_types()`	Decorate a model fit or sample with data types recovered from the input data
`gather_draws()` `spread_draws()`	Extract draws of variables in a Bayesian model fit into a tidy data format
`tidy_draws()`	Get a sample of posterior draws from a model as a tibble
`gather_emmeans_draws()`	Extract a tidy data frame of draws of posterior distributions of "estimated marginal means" (emmeans/lsmeans) from a Bayesian model fit.
`ungather_draws()` `unspread_draws()`	Turn tidy data frames of variables from a Bayesian model back into untidy data
Extracting fits, predictions, and residuals Get tidy draws from transformed linear predictors (“fits”), posterior predictions, or residuals
`add_fitted_draws()` `fitted_draws()` `add_linpred_draws()` `linpred_draws()` `add_predicted_draws()` `predicted_draws()` `add_residual_draws()` `residual_draws()`	Add draws from the posterior fit, predictions, or residuals of a model to a data frame
`add_draws()`	Add draws to a data frame in tidy format
Manipulating tidy data frames of draws Convenience functions for common data manipulation tasks with tidy data frames of draws
`sample_draws()`	Sample draws from a tidy-format data frame of draws
`compare_levels()`	Compare the value of draws of some variable from a Bayesian model for different levels of a factor
`gather_variables()`	Gather variables from a tidy data frame of draws from variables into a single column
`gather_pairs()`	Gather pairwise combinations of values from key/value columns in a long-format data frame
`reexports`	Objects exported from other packages
`combine_chains()`	Combine the chain and iteration columns of tidy data frames of draws
`density_bins()` `histogram_bins()`	Density bins and histogram bins as data frames
Point summaries, intervals, geoms, and stats For the `point_interval` family (`median_qi`, etc) and various `geom`s and `stat`s for visualizing posteriors, see the ggdist documentation
Deprecated functions Deprecated functions
`tidybayes-deprecated`	Deprecated functions, arguments, and column names in tidybayes
`predict_curve()` `predict_curve_density()`	Deprecated: Prediction curves for arbitrary functions of posteriors
