ecc: Create objects containing coordinates

In moonsun: Basic astronomical calculations with R

Description

These functions are simple way to create objects containing a set of horizontal (hoc), ecliptic (ecc) and equatorial (eqc) coordinates.

Usage

ecc(lat, long, names = NULL)
eqc(ra, d, names = NULL)
hoc(az, alt, names = NULL)

Arguments

lat	ecliptic latitude
long	ecliptic longitude
ra	right ascension
d	declination
az	azimuth
alt	altititude
names	names of objects

Details

All the arguments to these functions are vectors of the same length, containing corresponding coordinates and names. These are collected into a dataframe of appropriate class - eqc, ecc or hoc.

Value

An object of class eqc/ecc/hoc, apos, data.frame.
