marks
returns a matrix.marks(x) <- value
returns an object of class "ssf"
.as.owin
returns a window (object of class "owin"
).as.ppp
and unmark
return a point pattern (object of class "ppp"
).print
returns NULL
.range
returns a numeric vector of length 2.
min
and max
return a single numeric value.integral
returns a numeric value (if x
had numeric
values) or a numeric vector (if x
had vector values).
"ssf"
