Histogram of Z-Statistics

Source: R/zplot.R
hist.zplot_brma.Rd

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.

Value

NULL invisibly for base graphics, or a ggplot2 object.

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.
