heatplot: Make colorful scatter plots where the color show relative...

In geneorama/geneorama: Gene's collection of miscellaneous functions

Description

Simple way to make scatter plot heatmaps

Usage

heatplot(
  x,
  y,
  z,
  bgcol = "#777044",
  coltype = "heat",
  ccex = 1.5,
  circles = TRUE,
  ...
)

Arguments

x	vector for x position
y	vector for y position
z	vector for point size
bgcol	Background color. Default is a brown color: "#777044"
coltype	What family of colors to use. Default is "heat"
ccex	Controls point size. Default is 1.5
circles	Do you want circles drawn around the plots? (can be bad when there are a lot of points) Defaults to TRUE
...	Additional parameters passed to plot()

Details

Plots x-y points with color to indicate size.

Examples

N <- 1e4
DT <- data.table(x <- 1:N,
				 y <- -exp(-x/3000-100) * 5e44 + 30 +
				 		 	rnorm(N, sd = 1 + (log(x/10)*.3)),
				 z <- sqrt(y) + rnorm(N, sd = 1 + (x*.03)))
DT[ ,plot(x,y)]
DT[ ,plot(x,z)]
DT[ ,heatplot(x,y,z)]
DT[ ,heatplot(x,y,z, circles=FALSE)]
