The functions defined here are methods for the generic
unstack. The functions expect a spatial object
x which has several columns of marks; they separate the columns,
and return a list of spatial objects, each having only one column of marks.
x has several columns of marks (i.e.
marks(x) is a
matrix, data frame or hyperframe with several columns),
y <- unstack(x) is a list of spatial objects, each of the same
y[[j]] is equivalent to
x except that it only includes
jth column of
x has no marks, or has only a single column of marks,
the result is a list consisting of one entry, which is
A list, of class
"solist", whose entries are objects of the
