makeAxis: Create an axis

In ncdfCF: Easy Access to NetCDF Files with CF Metadata Conventions

Create an axis

Description

With this method you can create an axis to use with new CFArray instances. Depending on the orientation argument and the type of the values argument an instance of a class descending from CFAxis will be returned.

Usage

makeAxis(name, group, orientation, values, bounds = NULL)

Arguments

name	Name of the axis.
group	Group to place the axis in.
orientation	The orientation of the axis. Must be one of "X", "Y", "Z", or "T" for longitude, latitude, height or depth, and time axes, respectively. For any other axis, indicate an empty string ""
values	The coordinate values.
bounds	The bounds of the coordinate values, or NULL if not available.

Details

There are several restrictions on the combination of orientation and values arguments. Longitude and latitude axes (orientation of "X" or "Y") must have numeric values. For a time axis (orientation of "T") the values argument must be an instance of CFTime or CFClimatology.

Value

An instance of a class descending from CFAxis.
