drawn on the plot.
the number of tick-marks to use.
the axis style to use (see par).
further arguments to image.

Plots an object of class matrix in its original row and column
orientation. This means, in a plot the columns become the x-coordinates
and the reversed rows the y-coordinates.
If x is of class dist it is coerced to full-storage
matrix representation.
x <- matrix(sample(c(FALSE, TRUE),100,rep=TRUE),ncol=10,
dimnames=list(1:10,LETTERS[1:10]))
implot(x)
implot(x, col=c("white","black"), axes = TRUE)
