spatstat 1.44-1
29 December 2015
We thank Brian Ripley for contributions.
OVERVIEW
-
Urgent bug fix.
-
More support for replicated point patterns.
-
More support for tessellations.
-
Version nickname: “Gift Horse”
NEW FUNCTIONS
-
as.function.tess Convert a tessellation to a function(x,y). The function value indicates which tile of the tessellation contains the point (x,y).
-
tileindex Determine which tile of a tessellation contains a given point (x,y).
-
persp.leverage.ppm Method for persp plots for objects of class leverage.ppm
-
AIC.mppm, extractAIC.mppm AIC for point process models fitted to replicated point patterns.
-
nobs.mppm, terms.mppm, getCall.mppm Methods for point process models fitted to replicated point patterns.
SIGNIFICANT USER-VISIBLE CHANGES
-
anova.mppm Now handles Gibbs models, and performs the adjusted composite likelihood ratio test.
-
update, step These functions now work for models of class ‘mppm’.
-
textureplot Argument x can now be something acceptable to as.im
-
logLik.mppm New argument ‘warn’.
BUG FIXES
-
nncross.lpp, nnwhich.lpp, distfun.lpp Caused a segmentation fault. [Spotted by Brian Ripley.] Fixed.
-
anova.ppm If a single ‘object’ was given, and the object was a Gibbs model, then ‘adjust’ was effectively set to FALSE. Fixed.
