The argument X
may be
- a point pattern
(an object of class
"ppp"
) - a line segment pattern
(an object of class
"psp"
) - an object of class
"splitppp"
(basically a list of point patterns, obtained fromsplit.ppp
).
rshift
is generic, with
methods for the three classes "ppp"
,
"psp"
and "splitppp"
. See the help pages for these methods, rshift.ppp
,
