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

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

Examples

d <- data.frame(x=rnorm(1000),y=rnorm(1000))
s <- rep(FALSE,1000)
s[sample(1:length(s),100)] <- TRUE
create.scatter.dens.points(d,s)
