Generates sampling points using simple random sampling within a study area.
Usage
ss_random(x, n, seed = NULL)
Arguments
- x
An sf object representing the study area (polygon geometry).
- n
Integer, the number of sampling points to generate.
- seed
Optional integer seed for reproducibility.
Value
An object of class ss_samples containing:
- samples
An sf object with the sampling points.
- method
Character, "simple_random".
- n_samples
Integer, number of samples.
- crs
The coordinate reference system.
Details
Simple random sampling selects locations uniformly at random within the
study area. Each location has an equal probability of being selected.
Examples
if (FALSE) { # \dontrun{
library(sf)
poly <- st_polygon(list(rbind(c(0, 0), c(100, 0), c(100, 50), c(0, 50), c(0, 0))))
study_area <- st_sf(geometry = st_sfc(poly))
samples <- ss_random(study_area, n = 20)
plot(samples)
} # }
