mplot3: Image (False color 2D)Draw a bitmap from a matrix of values. This is a good way to plot a large heatmap

par.reset = TRUE, ...)Input matrix
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.
Colors to use. Defaults to colorGrad(100)
Matrix of same dimensions as z (Optional): Will be printed as strings over cells
Color for cell.labs. If NULL, the upper and lower quartiles will be
set to "white", the rest "black".
Background color
String (Optional): Path to file where image should be saved. R-supported extensions: ".pdf", ".jpeg", ".png", ".tiff".
Output Width in inches
Output height in inches
Logical: If TRUE, par will be reset to original settings before exit. Default = TRUE
Additional arguments to be passed to graphics::image
Logical: If TRUE, reverse rows. Defaults to TRUE for a top-left to bottom-right diagonal
This function calls image which is a lot faster than drawing heatmaps
