LabelPoints: Add text labels to a ggplot2 plot

In ibseq/scs-analysis: Tools for Single Cell Genomics

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
...	Extra parameters passed to geom_text

Value

A ggplot object

Examples

data("pbmc_small")
ff <- TopFeatures(object = pbmc_small[['pca']])
cc <- TopCells(object = pbmc_small[['pca']])
plot <- FeatureScatter(object = pbmc_small, feature1 = ff[1], feature2 = ff[2])
LabelPoints(plot = plot, points = cc)
