points_in_circle: Find points within radius around one or more center coordinates

Description

Deprecated.

`points_in_circle()` was renamed to [points_within_radius()].

This function selects rows from a data frame whose longitude/latitude coordinates fall within a given radius (in meters) from one or more specified center points. It also calculates the distance of each point to the center.

Usage

points_in_circle(
  data,
  lon_center,
  lat_center,
  lon = lon,
  lat = lat,
  radius = 200,
  sort = TRUE
)
points_within_radius(
  data,
  lon_center,
  lat_center,
  lon = "lon",
  lat = "lat",
  radius = 200,
  sort = TRUE
)

Value

A data frame subset of `data` with an extra column `distance_m` and if multiple centers are provided, also a column `center_index`.

Arguments

data

A data frame containing at least longitude and latitude columns.

lon_center

Numeric scalar or vector, longitude(s) of the circle center(s).

lat_center

Numeric scalar or vector, latitude(s) of the circle center(s).

lon

A string with the name of the longitude column in `data`.

lat

A string with the name of the latitude column in `data`.

radius

Numeric, circle radius in meters. Default is 200.

sort

Logical, if `TRUE` results are sorted by distance within each center.
