Below is an updated version of the image.scale function. In the old version, one had to constantly use additional arguments to suppress axes and their labels. The new version contains the additional arguments axis.pos (1, 2, 3, or 4) for defining the side of the axis, and add.axis (TRUE or FALSE), for defining whether the axis is plotted. Based on the position of the axis, the scale color levels are automatically drawn in a horizontal (axis.pos = 1[bottom] or 3[top]) or vertical (axis.pos = 2[left] or 4[right]) orientation. For the right plot above, the argument add.axis=FALSE so that additional control over axis ticks and labels could be added in an additional step with axis(). The function mtext() can be used to add additional labels to the scale.
