setmarks {spatstat} | R Documentation |
Create a marked point pattern from given point locations and given marks.
setmarks(X, m) X
X |
Point pattern (object of class "ppp" )
|
m |
Vector of mark values (of any atomic mode) |
This function is a shortcut which creates a marked point pattern
from a given point pattern X
and a given vector m
by attaching the marks in m
to the locations of the points
in X
.
If X
is already a marked point pattern, then its marks
are ignored and replaced by the values in m
.
The length of m
must agree with the number of points in
X
.
Use unmark
to remove marks.
Use ppp
to create point patterns in more general
situations.
Marked point pattern (object of class "ppp"
)
identical to X
except that it has marks equal to m
.
