Create sampling points based on random sampling grid centroids.

Selects sampling points within a grid defined by X and Y ranges and a specified cell size, employing a random sampling strategy.

randomSamp(n, xrange, yrange, cellsize)

Arguments

n

Number of sampling points to be created.

xrange

Vector of two elements idnicating x coordinates range (min,max).

yrange

Same as above for y range.

cellsize

Cell size for grid (minimum dist between points)

Details

Value

Returns a table of coordinates of the sampling sites.

# Create 25 random sampling sites in a 100x100 grid.
sampling <- randomSamp(25, c(0,100), c(0,100), 5)
plot(sampling, pch = 16, col = "red",
     xlab = "x", ylab = "y",
     main = "Random sampling sites")
