Draw image (False color 2D)

Description

Draw a bitmap from a matrix of values.

Usage

mplot3_img(
  z,
  as.mat = TRUE,
  col = NULL,
  xnames = NULL,
  xnames.y = 0,
  ynames = NULL,
  main = NULL,
  main.adj = 0,
  x.axis.side = 3,
  y.axis.side = 2,
  x.axis.line = -0.5,
  y.axis.line = -0.5,
  x.axis.las = 0,
  y.axis.las = 1,
  x.tick.labs.adj = NULL,
  y.tick.labs.adj = NULL,
  x.axis.font = 1,
  y.axis.font = 1,
  xlab = NULL,
  ylab = NULL,
  xlab.adj = 0.5,
  ylab.adj = 0.5,
  xlab.line = 1.7,
  ylab.line = 1.7,
  xlab.padj = 0,
  ylab.padj = 0,
  xlab.side = 1,
  ylab.side = 2,
  main.col = NULL,
  axlab.col = NULL,
  axes.col = NULL,
  labs.col = NULL,
  tick.col = NULL,
  cell.lab.hi.col = NULL,
  cell.lab.lo.col = NULL,
  cex = 1.2,
  cex.ax = NULL,
  cex.x = NULL,
  cex.y = NULL,
  zlim = NULL,
  autorange = TRUE,
  pty = "m",
  mar = NULL,
  asp = NULL,
  ann = FALSE,
  axes = FALSE,
  cell.labs = NULL,
  cell.labs.col = NULL,
  cell.labs.autocol = TRUE,
  bg = NULL,
  theme = getOption("rt.theme", "white"),
  autolabel = letters,
  filename = NULL,
  file.width = NULL,
  file.height = NULL,
  par.reset = TRUE,
  ...
)

Arguments

z	Input matrix
as.mat	Logical: If FALSE, rows and columns of z correspond to x and y coordinates accoridngly. This is the image default. If TRUE (default), resulting image's cells will be in the same order as values appear when you print z in the console. This is t(apply(z, 2, rev)). In this case, you can think of z as a table of values you want to pictures with colors. For example, you can convert a correlation table to a figure. In this case, you might want to add cell.labs with the values. Consider first using ddSci.
col	Colors to use. Defaults to colorGrad(100)
cell.labs	Matrix of same dimensions as z (Optional): Will be printed as strings over cells
cell.labs.col	Color for cell.labs. If NULL, the upper and lower quartiles will be set to "white", the rest "black".
bg	Background color
filename	String (Optional): Path to file where image should be saved. R-supported extensions: ".pdf", ".jpeg", ".png", ".tiff".
file.width	Output Width in inches
file.height	Output height in inches
par.reset	Logical: If TRUE, par will be reset to original settings before exit. Default = TRUE
...	Additional arguments to be passed to graphics::image

Details

This is also a good way to plot a large heatmap. This function calls image which is a lot faster than drawing heatmaps
