R Documentation

Add Isopycnal Curves to TS Plot

Description

Adds isopycnal lines to an existing temperature-salinity plot. This is called by plotTS(), and may be called by the user also, e.g. if an image plot is used to show TS data density.

Usage

drawIsopycnals(
  nlevels = 6,
  levels,
  rotate = TRUE,
  rho1000 = FALSE,
  digits = 2,
  eos = getOption("oceEOS", default = "gsw"),
  cex = 0.75 * par("cex"),
  col = "darkgray",
  lwd = par("lwd"),
  lty = par("lty")
)

Arguments

`nlevels`	suggested number of density levels (i.e. isopycnal curves); ignored if `levels` is supplied.
`levels`	optional density levels to draw.
`rotate`	boolean, set to `TRUE` to write all density labels horizontally.
`rho1000`	boolean, set to `TRUE` to write isopycnal labels as e.g. 1024 instead of 24.
`digits`	number of decimal digits to use in label (supplied to `round()`).
`eos`	equation of state to be used, either `"unesco"` or `"gsw"`.
`cex`	size for labels.
`col`	color for lines and labels.
`lwd`	line width for isopycnal curves
`lty`	line type for isopycnal curves

Value

None.
