| rshift {spatstat} | R Documentation |
Randomly shifts the points of a point pattern or line segment pattern. Generic.
rshift(X, ...)
X |
Pattern to be subjected to a random shift.
A point pattern (class "ppp"),
a line segment pattern (class "psp")
or an object of class "splitppp".
|

Arguments controlling the generation of the random shift vector, or specifying which parts of the pattern will be shifted. |
This operation applies a random shift (vector displacement) to the points in a point pattern, or to the segments in a line segment pattern.
The argument X may be
"ppp")
"psp")
"splitppp"
(basically a list of point patterns, obtained from
split.ppp).
The function rshift is generic, with
methods for the three classes "ppp",
"psp" and "splitppp".
See the help pages for these methods, rshift.ppp,
rshift.psp and
rshift.splitppp, for further information.
An object of the same type as X.
