Spatstat: tessellation problems.

The bug that caused the following error message ..

quadratcount(X, tess=Z)
Warning message:
In quadratcount.ppp(X, tess = Z) :
 Tessellation does not contain all the points of X

.. has been fixed in the next version of spatstat (1.20-4) 
which has just been sent to CRAN.

Adrian
