circular (version 0.1)

Circular: Create Objects of class circular for Circular data.

Description

The function circular is used to create circular objects. as.circular and is.circular coerce an object to a circular and test whether an object is a circular data.

Usage

circular(x, type = c("angles", "directions"), units = c("radians", "degrees"), template = c("none", "geographics"), modulo = c("asis", "2pi", "pi"), zero = 0, rotation = c("counter", "clock"), names)
as.circular(x, ...)
is.circular(x)
## S3 method for class 'circular':
print(x, info=TRUE, ...)

Arguments

x

a vector or a matrix.

type

the type of measures (Not Used Yet).

units

units of the measures.

template

how the data should be plotted (Until now only 'geographics' style is available).

modulo

if we need to reduce the measures to modulo.

zero

the zero of the axes (in radians).

rotation

the orientation of the axes.

names

names of the data.

info

if TRUE information on the properties of the data are printed.

...

parameters passed to circular for as.circular and to print.default for print.circular.

Value

• an object of class circular

Examples

x <- circular(c(pi, pi/3, pi/4))
print(x)
is.circular(x)
