k
random points independently in each tile.rstrat(win=square(1), nx, ny=nx, k = 1)
"ppp"
). The bounding rectangle of win
is divided into
a regular $nx \times ny$ grid of rectangular tiles.
In each tile, k
random points are generated independently
with a uniform distribution in that tile.
Some of these grid points may lie outside the window win
:
if they do, they are deleted.
The result is a point pattern inside the window win
.
This function is useful in creating dummy points for quadrature
schemes (see quadscheme
) as well as in simulating
random point patterns.
