NScluster 1.3.6-5 (2026-03-26)

• Changed package maintainer.

NScluster 1.3.6-4 (2025-04-30)

• Fixed Fortran compilation errors reported as ERROR in CRAN package check results.

NScluster 1.3.6-3

• Fixed problems with Rd files reported as NOTE in CRAN package check results.

NScluster 1.3.6-2

• Specified all variable types explicitly instead of using implicit variable types.

NScluster 1.3.6

• Removed C wrapper functions and registered entry points for the routines accessed by the .Fortran interface to call Fortran subroutines.

• Added a ‘NEWS.md’ file.

NScluster 1.3.5 (2021-05-28)

• Added JSS registration information to the ‘DESCRIPTION’ file and the help page references.

• Added a ‘CITATION’ file.

NScluster 1.3.4 (2019-12-02)

• Removed unused or undefined variables in Fortran COMMON blocks.

NScluster 1.3.3 (2019-12-01)

• Fixed LTO (Link-Time Optimization) problems reported in CRAN package check results.

• Changed the specification of boot.mple(), i.e., by setting of random seed reproduction was enabled.

• Added new argument trace = FALSE to boot.mple() to enable/disable progress bar.

NScluster 1.3.1 (2019-02-22)

• Removed Simulatexxxxx(), Estimatexxxxx() and Palmxxxxx() functions, and replaced them with the main functions sim.cppm(), mple.cppm() and palm.mple() with model argument for simulation, MPLEs (the maximum Palm likelihood estimates), nonparametric and parametric estimation of Palm intensity.

• Added a new function boot.mple() to perform the bootstrap by repeatedly simulating and fitting point patterns under the fitted model.

• Added S3 methods plot(), coef() and summary() for returned class objects.

• Added AIC calculations to evaluate models in the mple.cppm() function.

• Added defaults for initial values of mple.cppm().

• Revised the guide so that it can be referenced in vignette("NScluster").

NScluster 1.2.0 (2018-03-19)

• Changed the implementation of the random number generator to Mersenne-Twister.

• Changed the names of simplex functions to EstimateIP(), EstimateThomas(), EstimateTypeA(), EstimateTypeB() and EstimateTypeC().

• Changed the range of x and y labels in the output plots of the Estimatexxxxx() functions.

• Removed ty arguments from PalmIP(), PalmThomas(), PalmTypeA(), PalmTypeB() and PalmTypeC(). Fixed ty = 1 in R programs.

• Renamed arguments x2 to uplimit = 0.3 of functions EstimateIP(), EstimateTypeA(), PalmIP() and PalmTypeA().

• Renamed arguments offspring to data of Estimate functions and Palm functions.

• Added default values 0.001 for delta of Palm functions.

• Instead of removing the pa argument of the Palm function, the vector of true parameters par1 = NULL and the vector of MPLEs par2 = NULL have been added.

• Added new arguments parents.distinct = FALSE to SimulateTypeB() and SimulateTypeC() to distinguish between two groups of plotted points.

• Added ‘src/init.c‘.

NScluster 1.1.1 (2016-12-15)

• Merged NSclusterOMP package (parallel versions of parameter estimation by the simplex method) into NScluster package.

• Fixed Fortran code according to the warning message when using gfortran with -Wall -pedantic.

• Fixed Simplex-IPfp.f, Simplex-TypeAfp.f, Plam-IPf.f and Palm-TypeAf.f for error handling.

• Corrected True value to Initial value in the expression of simplex function outputs.

• Removed MPLE : simplex and normalized outputs from simplex functions.

• Added legends to plots of simplex functions.

NScluster 1.1.0 (2016-12-14)

• Corrected PKG_LIBS in ‘NScluster/src/Makevars’ to $(SHLIB_OPENMP_CFLAGS). (Reported by Brian Ripley.)

• Removed the setOmpNumThread() function.

NScluster 1.0.2 (2014-08-09)

• Corrected ‘inst/doc/index.html’ according to the error message for the W3C Markup Validation Service.

• Reduced example in SimplexThomas() to less than 5 sec.

NScluster 1.0.1

• Removed ‘inst/LICENCE’ and added ‘inst/OUTHORS’.
