Description

Add text labels to a ggplot2 plot

Usage

LabelPoints(
  plot,
  points,
  labels = NULL,
  repel = FALSE,
  xnudge = 0.3,
  ynudge = 0.05,
  ...
)

Arguments

plot

A ggplot2 plot with a GeomPoint layer

points

A vector of points to label; if NULL, will use all points in the plot

labels

A vector of labels for the points; if NULL, will use rownames of the data provided to the plot at the points selected

repel

Use geom_text_repel to create a nicely-repelled labels; this is slow when a lot of points are being plotted. If using repel, set xnudge and ynudge to 0

xnudge, ynudge

Amount to nudge X and Y coordinates of labels by
