addSpine: Add a spine to a section object

Description Usage Arguments Value Author(s) Examples

Description

The purpose of this is to permit plotting with xtype="spine", so that the section plot will display the distance of stations projected onto the spine.

Usage

1
addSpine(section, spine, debug = getOption("oceDebug"))

Arguments

section

a section object.

spine

either a list or a data frame, containing numeric items named longitude and latitude, defining a path along the spine.

debug

an integer specifying whether debugging information is to be printed during the processing. This is a general parameter that is used by many oce functions. Generally, setting debug=0 turns off the printing, while higher values suggest that more information be printed. If one function calls another, it usually reduces the value of debug first, so that a user can often obtain deeper debugging by specifying higher debug values.

Value

A section object with a spine added.
