- Added support for nested-Rhat via
`rhat_nested`

(#256) - Added support for indexing draws in
`rvar`

s using`rvar`

s (#282):`x[i]`

or`x[i] <- y`

where`i`

is a scalar logical`rvar`

slices (or updates)`x`

by its draws. Thus, if`y <- x[i]`

, then`y`

is the same shape as`x`

but with`sum(i)`

draws.`x[[i]]`

or`x[[i]] <- y`

where`i`

is a scalar numeric rvar slices (or updates)`x`

by selecting the`i`

th element within each corresponding draw. Thus, if`y <- x[[i]]`

, then`y`

is an`rvar`

of length 1.

- Added
`rvar_ifelse()`

, which is a variant of`ifelse()`

that accepts (and returns)`rvar`

s (#282). - Array broadcasting for
`rvar`

s has been made faster.

- Ensure
`rfun()`

works with primitive functions (#290) and dots arguments (#291). - Provide implementations of
`vctrs::vec_proxy_equal()`

,`vctrs::vec_proxy_compare()`

, and`vctrs::vec_proxy_order()`

. - Minor future-proofing of
`cbind(<rvar>)`

,`rbind(<rvar>)`

, and`chol(<rvar>)`

for R 4.4 (#304). - Ensure that
`bind_draws(<draws_rvars>)`

regenerates draw ids when binding along chains or draws; this also fixes a bug in`split_chains(<draws_rvars>)`

(#300).

- Delay applying
`tibble::num()`

formatting to output from`summarise_draws()`

until`print()`

is called so that summary output can be easily converted to a vanilla data frame (#275).

- Added new
`rvar_factor()`

and`rvar_ordered()`

subtypes of`rvar()`

that work analogously to`factor()`

and`ordered()`

(#149). See the new section on`rvar_factor`

s in`vignette("rvar")`

. - The
`draws_df()`

,`draws_list()`

, and`draws_rvars()`

formats now support discrete variables stored as`factors`

/`ordered`

s (or`rvar_factor`

s /`rvar_ordered`

s). If converted to formats that do not support discrete variables with named levels (`draws_matrix()`

and`draws_array()`

), factor-like variables are converted to`numeric`

s. - Made
`match()`

and`%in%`

generic and added support for`rvar`

s to both functions. - Added
`modal_category()`

,`entropy()`

, and`dissent()`

functions for summarizing discrete draws. - Allow lists of draws objects to be passed as the first argument to
`bind_draws()`

(#253). - Improving formatting of
`summarise_draws`

output via`tibble::num`

. `print.rvar()`

and`format.rvar()`

now default to a smaller number of significant digits in more cases, including when printing in data frames. This is controlled by the new`"posterior.digits"`

option (see`help("posterior-package")`

).- Implemented faster
`vec_proxy.rvar()`

and`vec_restore.rvar()`

, improving performance of`rvar`

s in`tibble`

s (and elsewhere`vctrs`

is used).

- Ensure that
`as_draws_rvars()`

preserves dimensions of length-1 arrays (#265). - Fix some minor compatibility issues with
`rvar`

,`vctrs`

,`dplyr`

, and`ggplot2`

(#267, #269).

- Minor release that fixes some CRAN check failures.

- Implement
`for_each_draw(x, expr)`

, which executes`expr`

once for each draw of`x`

, exposing variables in`x`

as arrays of the shape implied by the indices in their names (#224). - Implement
`subset_draws()`

,`thin_draws()`

, and`resample_draws()`

for`rvar`

s (#225). - Allow
`weights`

to be optional in`resample_draws()`

(#225). - Add an implementation of
`drop()`

for`rvar`

s. - Speed up subsetting of
`draws_list`

objects. (#229, #250)

- Support remaining modes of
`diag()`

for`rvar`

s (#246). - Better parsing for named indices in
`as_draws_rvars()`

, including nested use of`[`

, like`x[y[1],2]`

(#243). - Allow 0-length
`rvar`

s with`ndraws() > 1`

(#242). - Ensure 0-length
`rvar`

s can be cast to`draws`

formats (#242). - Donâ€™t treat length-1
`rvar`

s with more than 1 dimension as scalars when casting to other formats (#248).

- Improve the
`mcse_sd`

function to not make a normality assumption. (#232)

- Correctly transform lists of data.frames into
`draws_list`

objects. - Correctly drop variables on assigning
`NULL`

in`mutate_variables`

. (#222)

- support casting to/from
`rvar`

and`distributional::dist_sample`

(#109)

- fix hidden variables in
`bind_draws.draws_df`

when binding more than two objects thanks to Jouni Helske (#204) - fix output of
`pillar::glimpse()`

when used on a data frame containing`rvar`

s (#210) - drop
`"draws"`

and`"draws_df"`

classes from`draws_df`

objects if meta data columns are removed by a`dplyr`

operation (#202) - fix output of
`print.draws_df()`

on objects with unrepaired draws (#217) - ensure
`variance()`

works properly with`summarise_draws()`

(#219)

- use
`matrixStats`

to speed up convergence functions (#190) and`rvar`

summaries (#200)

- ensure that
`as_draws_rvars()`

works on lists of lists (#192) - fix some vector recycling issues with
`rvar_rng`

(#195) - ensure that
`subset_draws()`

respects input variable order, thanks to Karl Dunkle Werner and Alexey Stukalov (#188)

- No longer check for constant-per-chain input in effective sample
size diagnostics as this is overly conservative especially for
`ess_tail`

. (#198)

- ensure that all unit tests pass on all CRAN environments
- fix a problem that sometimes lead to
`rvar`

s being unnecessarily slow (#179)

- initial CRAN release

- beta release
