tidy-format-translators: Translate between different tidy data frame formats for draws from distributions

Description

These functions translate tidybayes-style tidy data frames of draws to/from different tidy data frame formats (each format using a different naming scheme).

Usage

to_broom_names(data)
from_broom_names(data)
to_ggmcmc_names(data)
from_ggmcmc_names(data)

Arguments

A data frame to translate.

Value

A data frame with (possibly) new names in some columns, according to the translation scheme above.

• .variable <-> term

• .value <-> estimate

• .prediction <-> .fitted

• .lower <-> conf.low

• .upper <-> conf.high

to_ggmcmc_names() / from_ggmcmc_names():

• .chain <-> Chain

• .variable <-> Parameter

• .value <-> value

Examples

# NOT RUN {
library(magrittr)

data(line, package = "coda")

  gather_draws(alpha, beta, sigma) %>%
  median_qi() %>%
  to_broom_names()

# }
