create.scatter.dens.points: create.scatter.dens.points

In RnBeads: RnBeads

Description

Creates a scatterplot containing all points in a given data.frame. Points are colored according to point density. Optionally, a selection of points are shown in a different color

Usage

create.scatter.dens.points(
  df2p,
  is.special = NULL,
  dens.special = TRUE,
  mock = FALSE
)

Arguments

df2p	data.frame to be plotted. Only the fist two columns are taken into account as x and y coordinates respectively
is.special	boolean vector of length equal to the number of rows in df2p. Specifies which points should be highlighed seperately in a different color
dens.special	Flag indicating whether the points of the special population should be colored according to their density
mock	Should only the axis be plotted? useful when exporting scatterplots with lots of points as immage and the corresponding axis as vector graphics.

Value

ggplot object
