wrapper for image plotting a data matrix in the orientation of text display

Description

Wrapper around image to plot a matrix as it is displayed in R console, i.e. the field dat[1,1] is at the top left corner. It further allows to plot text into individual fields and have colored axis tick labels.

Usage

image_matrix(
  z,
  x,
  y,
  text,
  text.col,
  text.cex = 1,
  axis = 1:2,
  axis.cex = 1,
  cut = FALSE,
  breaks,
  axis1.col,
  axis1.las = 2,
  axis2.col,
  axis2.las = 2,
  ...
)

Arguments

z	the numeric data matrix to be plotted
x	optional x coordinates, corresponding to columns of z
y	optional y coordinates, corresponding to rows of z
text	a matrix of characters corresponding to dat which will be plotted on the image
text.col	individual colors for text fields
text.cex	relative font size for text fields
axis	integer vector, sets whether x-axis (1,3) and/or y-axis (2,4) are drawn; the column and row names of dat will be used as tick labels
axis.cex	if axis[1|2].col is provided, this sets the tick label size
cut	if TRUE data is cut at min and max of breaks.
breaks	breakst to use for color selection.
axis1.col	invididual colors for x-axis tick labels, length must equal the number of columns of dat
axis1.las	parameter las (tick label orientation) for x axis
axis2.col	invididual colors for y-axis tick labels, length must equal the number of rows of dat
axis2.las	parameter las (tick label orientation) for y axis
...	further arguments to image, e.g., col to select colors
