s2_point

Create an S2 Point Vector

Description

In S2 terminology, a "point" is a 3-dimensional unit vector representation of an s2_lnglat(). Internally, all s2 objects are stored as 3-dimensional unit vectors.

Usage

s2_point(x, y, z)

as_s2_point(x, ...)

## S3 method for class 's2_point'
as_s2_point(x, ...)

## S3 method for class 's2_lnglat'
as_s2_point(x, ...)

## S3 method for class 's2_geography'
as_s2_point(x, ...)

## S3 method for class 'matrix'
as_s2_point(x, ...)

## S3 method for class 's2_point'
as.data.frame(x, ...)

## S3 method for class 's2_point'
as.matrix(x, ...)

Arguments

`x, y, z`	Vectors of latitude and longitude values in degrees.
`...`	Unused

Value

An object with class s2_point

Examples

lnglat <- s2_lnglat(-64, 45) # Halifax, Nova Scotia!
as_s2_point(lnglat)
as.data.frame(as_s2_point(lnglat))
