		23 may 2010		
	
OVERVIEW
    New dataset: replicated 3D point patterns. 
    Improvements to Metropolis-Hastings simulation code.
    More support for hyperframes. Bug fixes.

NEW FUNCTIONS

    rbind.hyperframe
	  Method for rbind for hyperframes.

    as.data.frame.hyperframe
	  Convert hyperframe to data frame

NEW DATASETS

    osteo
           Osteocyte Lacunae data.
	   Replicated 3D point patterns.

IMPROVEMENTS/ENHANCEMENTS

    Fiksel
       Fitted point process models (class ppm) with the Fiksel()
       double exponential interaction can now be simulated by rmh.

    rmh.default
       Point processes with the Fiksel interaction can now be
       simulated by specifying parameters in rmh.default.

    logLik.ppm
           New argument 'warn' controls warnings.

    profilepl
           No longer issues spurious warnings.
  

BUGS

	[1] Hardcore, rmh, ppm
	        Simulations of a fitted model with the Hardcore interaction
		were completely wrong: the simulations were Poisson
		because the hard core radius was erroneously set to zero. 
		This affected rmh and ppm(method="ho").
		Fixed.

	[2] fitin
	        A plot of the pairwise interaction function of a fitted model,
		generated by plot(fitin(model)) where model <- ppm(...), 
		was sometimes incorrect when the model included a hard core.
		Fixed.
