ez (version 3.0-1)

ezBootPlot: Function to plot bootstrapped predictions and confidence intervals.

Description

This function provides easy visualization of any given user-requested effect from the bootstrap predictions computed by ezBoot.

Usage

ezBootPlot(
    from_ezBoot
    , confidence = .95
    , x
    , split = NULL
    , row = NULL
    , col = NULL
    , do_lines = TRUE
    , bar_width = NULL
    , to_numeric = NULL
    , x_lab = NULL
    , y_lab = NULL
    , split_lab = NULL
    , levels = NULL
    , diff = NULL
    , reverse_diff = FALSE
    , row_y_free = FALSE
    , alarm = TRUE
)

Arguments

from_ezBoot
An list object resulting from a call to ezBoot.
confidence
Numeric vector of one or more confidence levels to use for plotting error bars. If plotting multiple confidence regions, it is suggested that an equal number of different values are supplied to the bar_width argument for differentiation.
x
.() object specifying the variable to plot on the x-axis.
split
Optional .() object specifying a variable by which to split the data into different shapes/colors (and line types, if do_lines==TRUE).
row
Optional .() object specifying a variable by which to split the data into rows.
col
Optional .() object specifying a variable by which to split the data into columns.
do_lines
Logical. If TRUE, lines will be plotted connecting groups of points.
bar_width
Optional numeric value specifying custom widths for the error bar hat. Must either have a length of 1, or the same length as confidence.
to_numeric
Optional .() object specifying any variables that need to be converted to the numeric class before plotting.
x_lab
Optional character string specifying the x-axis label.
y_lab
Optional character string specifying the y-axis label.
split_lab
Optional character string specifying the key label.
levels
Optional named list where each item name matches a factored column in data that needs either reordering of levels, renaming of levels, or both. Each item should be a list containing named elements new_order or new_names
diff
Optional .() object specifying a 2-level varbiable to collapse to a difference score.
reverse_diff
Logical. If TRUE, triggers reversal of the difference collapse requested by diff.
row_y_free
Logical. If TRUE, then rows will permit different y-axis scales.
alarm
Logical. If TRUE (default), call the alarm function when ezBootPlot completes.

Value

  • A list with 4 components:
  • plotA printable/modifiable ggplot2 object.
  • cellsA data frame containing predictions for each cell in the requested design.
  • bootsA data frame containing each iteration of bootstrap predictions, collased to the requested design.
  • boot_statsA data frame containing the "lo" and "hi" bounds of the 95 percent bootstrap confidence interval of each cell in the requested design.
