syr1
, syr2
and syr3
are marked point patterns
of class "ppp" representing the coordinates of some sampling locations, 'marked' by
the value of some parameters (e.g. density of individuals) measured on them. See ppp.object
for details of the format. On the other hand, one can use function haz.ppp
to easily build ppp
objects
appropriate for use with syrjala.test
.
