	* correction of backtransformation in the CKrige example (CKrige.Rd)


2010-08-04 Christoph Hofer

   * Punktkriging korrigiert so dass jetzt auch zwischen Messfehler und kleinräumiger Varianz unterschieden werden kann

   * k in K geändert bei der Ausgabe der Punktkriging Vorhersagen


2011-01-13 Christoph Hofer

	* warings werden erzeugt falls CK oder CMCK nicht existiert
	* M für die rücktransformation korrigiert sqrt(dist)


2011-01-13 Christoph Hofer


	* plot.preCKrige geändert (Zeile 48) (Hinweis von A. Papritz)
	* Auswahl der zufälligen Farben war auf 155 beschränkt
 	* jetzt entspricht die Anzahl der Anzahl Polygone
	* if statement im File f.bb.cov.one.configuration.R (Zeile 65) erweitert
	* mit no.pix.in.poly[ t.element.index[ k, 1 ] ] == 0 &&
	*  sa.polygons[ t.element.index[ k, 2 ] ] == T |
	*  no.pix.in.poly[ t.element.index[ k, 2 ] ] == 0 &&
	*  sa.polygons[ t.element.index[ k, 1 ] ] == T
	* somit wir die Punkt-Punkt-Kovarianz zwischen Blöcken berechnet die keine Pixel enthalten aber 
	* von der Fläche genug Gross wären (wurde vorher nicht berücksichtigt)

	* simple kriging weights wurden falsch ausgegeben
	* file f.polygons.CKrige.R wurde in Zeile 199 korrigiert


2012-04-24 Christoph Hofer
	
	* changed Package startup functions from .noLoad to .onAttach and
	* the cat function for the startup text changed to Packagestartupmessage


2012-11-11 Christoph Hofer

	* replacement of gpclib package by the package rgeos
	* changes in function f.intersect.area
	* instead of area.poly( intersect( gpc.pixel, polygons))
	* I have to use the try method since the intersect method of rgeos returns for 
	* non-overlapping polygons an error
 
		area <- try( area.poly( try( intersect( gpc.pixel, polygons ), silent = T ) ), silent = T )
                if( is( area ) == "try-error" ){ area <- 0}
                return( area )


2012-11-21

	* based on the wish of Andreas Papritz the function f.point.block.cov is included in the export in the namespace



2012-11-29


	* corrected spelling error in the description file based on a comment of Jason Matney


2012-11-30

	* I supplemented the if statement in the hidden function f.intersect.area.R
	* by the terms length( area ) == 1 to
        * if( length( area = 1) && is( area ) == "try-error" ){ area <- 0}
	* since the if statement produced a warning   when  area was a vector


2012-12-23

	* in version 0.1.9 all examples are ignored as the step
	* -- running examples for arch … since their compilation
	* take to much time

2013-06-13
        * based on a comment by Andreas Papritz
	* in f.point.block.cov row and colwidth value was mixed up for the rxwidth and rywidth argument in the   
	  f.point.rec.covmat -> Covariance between point an polygons discretised by non-quadratic pixels was wrong
 	* this bug is now fixed 
2013-06-16
	* covmodel "whittlematern" is no longer in use
	* two new covmodels are added: "matern" and "whittle" see Randomfields package
2013-06-16
	* the supplement in the hidden function f.intersect.area.R is not needed anymore since rgeos 0.2-17 can 
	* can handel gpc.poly objects
2013-10-02
	* Package methods and spatialCovariance imported by the Namespace
2015–04-22
	* S3method(print , …) added in the Namesapce file also S3method(summary,…) and S3method(plot, ….)
