hist.zplot_brma: Histogram of Z-Statistics

In RoBMA: Robust Bayesian Meta-Analyses

Histogram of Z-Statistics

Description

Plots a histogram of observed z-values from the meta-analysis.

Usage

## S3 method for class 'zplot_brma'
hist(
  x,
  plot_type = "base",
  from = -6,
  to = 6,
  by = 0.5,
  length.out = NULL,
  add = FALSE,
  plot_thresholds = TRUE,
  dots_thresholds = NULL,
  dots_hist = NULL,
  dots_all = NULL,
  ...
)

Arguments

x	a zplot_brma object.
plot_type	graphics system: "base" or "ggplot". Defaults to "base".
from, to	z-value range for plotting. Defaults to -6 and 6.
by	bin width. Defaults to 0.5.
length.out	number of bins (alternative to by).
add	whether to add to existing plot. Defaults to FALSE.
plot_thresholds	whether to show significance threshold lines. Defaults to TRUE.
dots_thresholds	graphical parameters for threshold lines (list).
dots_hist	graphical parameters for histogram (list).
dots_all	graphical parameters passed to all components (list).
...	additional graphical parameters.

Details

Z-statistics are computed as effect size divided by standard error (yi / sei). Histogram bins are adjusted to align with significance thresholds when selection model priors are present.

Value

NULL invisibly for base graphics, or a ggplot2 object.
