s2_lnglat

Create an S2 LngLat Vector

Description

This class represents a latitude and longitude on the Earth's surface. Most calculations in S2 convert this to a as_s2_point(), which is a unit vector representation of this value.

Usage

s2_lnglat(lng, lat)

as_s2_lnglat(x, ...)

## S3 method for class 's2_lnglat'
as_s2_lnglat(x, ...)

## S3 method for class 's2_point'
as_s2_lnglat(x, ...)

## S3 method for class 's2_geography'
as_s2_lnglat(x, ...)

## S3 method for class 'matrix'
as_s2_lnglat(x, ...)

## S3 method for class 's2_lnglat'
as.data.frame(x, ...)

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

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

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

Arguments

`lat, lng`	Vectors of latitude and longitude values in degrees.
`x`	A `s2_lnglat()` vector or an object that can be coerced to one.
`...`	Unused

Value

An object with class s2_lnglat

Examples

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