ecc: Create objects containing coordinates

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

Value

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

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.

Examples

a = ecc(1:360,rep(0,360),1:360)
a
as.eqc(a)
plot(as.eqc(a))
