Plot topography data

Description

Plot contours of topographic data.

Usage

## S3 method for class 'topo':
plot(x, 
  water.z, water.col, water.lty, water.lwd,
  land.z,   land.col,  land.lty,  land.lwd,
  legend.loc="topright", ...)

Arguments

x an topo object, e.g. as read by read.topo.
water.z depths at which to plot water contours. If not provided, these are inferred from the data.
water.col colors corresponding to water.z values. If not provided, these will be "fill" colors from gebco.colors.
water.lty line type(s) for water contours
water.lwd line width(s) for water contours
land.z depths at which to plot land contours. If not provided, these are inferred from the data.
land.col colors corresponding to land.z values. If not provided, these will be "fill" colors from gebco.colors.
land.lty line type(s) for land contours
land.lwd line width(s) for land contours
legend.loc location for a legend (or FALSE, for no legend).
... additional arguments passed on to plotting functions

Details

The plot aspect ratio is set based on the middle latitude in the plot. Be aware that the ETOPO2 data are on a 2-minute (roughly 2-mile) spacing, and coastlines created with such data can be quite inaccurate on scales of 100km or less.

The line properties, such as land.lwd, may either be a single item, or a vector; in the latter case, the length must match the length of the corresponding properties, e.g. land.z.
