Prevent overlapping labels

Description

Determines clever placement of labels for plots made in base R

Usage

spreadLabels2(
  x,
  y,
  label,
  padding = 0,
  str.cex = par("cex"),
  str.font = par("font")
)

Arguments

x	The set of x coordinates for the points to plot
y	The set of y coordinates for the points to plot
label	A character vector of labels for each x,y pair.
padding	A numeric value representing the extra proportion of string size to add around each label. Not clear that this works as intended, so leave it at zero.
str.cex	The cex value for the label. Defaults to par("cex"). Passed to strwidth.
str.font	The font value for the label. Defaults to par("font"). Passed to strwidth.

Value

A matrix with 2 columns corresponding to x and y coordinates of the label centre to be used downstream as an input e.g. to text
