PP2 {pgs} | R Documentation |
Create a PointPattern-class
object representing a 2D point
pattern with 1,4,5,6,7,8 or 9 points lying in a rectangle.
PP2(n = 4, h = 1, v = h, h3 = TRUE)
n |
the number of points. Must be 1,4,5,6,7,8 or 9. Default, 4. |
h |
the horizontal side length of the rectangle. Default, 1. |
v |
the vertical side length of the rectangle. Default, h. |
h3 |
if TRUE , alignment of 3 points (see details below) are horizontal
(vertical if FALSE ). Used only for n =6, 7 or 8. |
When n
=4, the four points lie at the four corners of the
rectangle. When n
=5, the fifth point lies at the center of the
rectangle. When n
=6 (and h3
is TRUE
), four points
lie at the rectangle corners and the two other points lie at the
centres of the top and bottom edges. When n
=7 (and h3
is
TRUE
), the point pattern consists of 3 horizontal alignments of
2, 3 and 2 points. When n
=8 (and h3
is TRUE
), the point
pattern consists of 3 horizontal alignments of 3, 2 and 3 points.
When n
=9, the point pattern consists of 3 (horizontal or
vertical) alignments of 3 points.
