List of points for OpenCage queries

Create a list of points (latitude/longitude coordinate pairs) for OpenCage queries.

Usage

oc_points(...)

# S3 method for class 'numeric'
oc_points(latitude, longitude, ...)

# S3 method for class 'data.frame'
oc_points(data, latitude, longitude, ...)

Arguments

...

Ignored.

latitude, longitude

Numeric vectors of latitude and longitude values.

data

A data.frame containing at least 2 columns with latitude and longitude values.

Value

A list of points. Each point is a named vector of length 2 containing a latitude/longitude coordinate pair.

Examples

oc_points(-21.01404, 55.26077)
#> [[1]]
#>  latitude longitude 
#> -21.01404  55.26077 
#> 

xdf <-
  data.frame(
    place = c("Hamburg", "Los Angeles"),
    lat = c(53.5503, 34.0536),
    lon = c(10.0006, -118.2427)
  )
oc_points(
  data = xdf,
  latitude = lat,
  longitude = lon
)
#> [[1]]
#>  latitude longitude 
#>   53.5503   10.0006 
#> 
#> [[2]]
#>  latitude longitude 
#>   34.0536 -118.2427 
#>
