plot_intervals_unif {confinterpret}

Plot intervals as uniform (box) areas

Description

The current implementation of this function uses boxplot to draw its boxes.

Usage

plot_intervals_unif(intervals, estimates = NULL,
  interval_value_labels = FALSE, estimate_value_labels = FALSE,
  interval_labels_offset = c(0, 0, box_halfheight + 0.1, box_halfheight +
  0.1), estimate_labels_offset = c(0, box_halfheight + 0.1),
  plot_estimate_marks = FALSE, estimate_mark_points = c(1.2 *
  graphics::strheight("M"), 0.05, -1.2 * graphics::strheight("M"), -0.05), ...)

Arguments

intervals

The interval(s) to be plotted. Two column matrix.

estimates

Estimates for each of the intervals (optional).

interval_value_labels

Logical value specifying whether interval value labels are to be added.

estimate_value_labels

Logical value specifying whether estimate value labels are to be added.

interval_labels_offset

Amount to offset interval labels by from the centre of the end of the interval's plot. c(x1, x2, y1, y2).

estimate_labels_offset

Amount to offset estimate labels by. c(x, y). Normally want the estimate to be x-located at its value, but may want a y-offset to move it above or below the plot shape that represents the interval.

plot_estimate_marks

Whether to plot marks at the x location of the estimates.

estimate_mark_points

y positions of the ends of the estimate marks as a numeric vector of length 4. Values are, in order: start (relative to centre), end (relative to box top), start (relative to centre), end (relative to box bottom).

...

Further parameters to be passed on.

Details

The default value for the estimate_labels_offset parameter is defined in terms of a variable, box_halfheight. Because boxplot, the underlying plotting function, draws boxes different heights depending on the number of boxes drawn, this is set within the function. For one box the box_halfheight is 0.2; otherwise it is 0.4.
