Description

Designed to replicate like the cool-looking Figure 7 in Butterworth et al. (2003).

Usage

1
2
3
mountains(zmat, xvec = NULL, yvec = NULL, zscale = 3, rev = TRUE,
  nshades = 100, axes = TRUE, xaxs = "i", yaxs = "i", xlab = "",
  ylab = "", las = 1, addbox = FALSE, ...)

Arguments

zmat

A matrix where the rows represent the heights of each mountain range

xvec

Optional input for the x variable

yvec

Optional input for the y variable

zscale

Controls the height of the mountains relative to the y-axis and max(zmat)

rev

Reverse the order of the display of yvec values.

nshades

Number of levels of shading

axes

Add axes to the plot?

xaxs

X-axis as internal or regular (see ?par for details)

yaxs

Y-axis as internal or regular (see ?par for details)

xlab

Optional label for x-axis

ylab

Optional label for y-axis

las

Xxis label style (see ?par for details). Default = 1 = horizontal axis labels.

addbox

Puts a box around the whole plot
