plotImageRotated: Plot a rotated image plot

Description

plotImageRotated plots a raster/matrix using image() but supplying a rotated version of the matrix, i.e. it plots the matrix as it printed on the screen.

Usage

plotImageRotated(data, col.vals = c(), row.vals = c(), scale = TRUE,  col = heat.colors(20), zlim = range(data, na.rm = TRUE),  title = "", useRaster = TRUE, xlab = "", ylab = "", ...)

Arguments

data

matrix: data to be plotted

col.vals

numeric vector: coordinate values for the columns of data

row.vals

numeric vector: coordinate values for the rows of data

scale

logical: whether to plot a color scale besides the plot

col

color vector: colors to create the color scale.

zlim

numeric vector (length two): outer limits of the color-scale. Values above or below this range are colored brighter/darker than the maximum/minimum color (see ?plotColorScale).

title

character string: title of the color legend

useRaster

argument passed to image() to decide whether to draw polygons (FALSE) or use a bitmap raster (TRUE).

xlab

ylab

...

further arguments passed to image

Value

Details

The normal image() function always plots a rotated version of a matrix. This function rotates the input to image in a way that the first entry of the matrix (col=1, row=1) shows up at the top-left corner of the plot. In other words the way a matrix would be displayed by printing it directly mapped to the plot.
