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
.
