bounce: Separate plotting positions for labels, to avoid overlap

In jhmaindonald/DAAG: Data Analysis and Graphics Data and Functions

Description

Return univariate plotting positions in which neighboring points are separated, if and as necessary, so that they are the specified minimum distance apart.

Usage

bounce(y, d, log = FALSE)

Arguments

y	A numeric vector of plotting positions
d	Minimum required distance between neighboring positions
log	TRUE if values are will be plotted on a logarithmic scale.

Details

The centroid(s) of groups of points that are moved relative to each other remain the same.

Value

A vector of values such that, when plotted along a line, neighboring points are the required minimum distance apart.

Note

If values are plotted on a logarithmic scale, d is the required distance apart on that scale. If a base other than 10 is required, set log equal to that base. (Note that base 10 is the default for plot with log=TRUE.)
