Random location drawing
Description
This function draws random locations in longlat format.
Usage
rnd_locations(
nobs,
xmin = -180,
xmax = 180,
ymin = -90,
ymax = 90,
output_type = c("data.table", "data.frame", "sf")
)
Arguments
nobs |
number of observations |
xmin |
minimum longitude |
xmax |
maximum longitude |
ymin |
minimum latitude |
ymax |
maximum latitude |
output_type |
type of output object. Either |
Details
By default, this function draws a global sample of random locations. You can restrict it to a certain region via specifying xmin
, xmax
, ymin
,
and ymax
. The function draws from a uniform spatial distribution that assumes the planet to be a perfect sphere. The spherical assumption is common in GIS
functions, but deviates from Earth's exact shape.
Value
Returns a data.table, data.frame, or sf object of unprojected (longlat) points.
Examples
data <- rnd_locations(1000)
