0.92 * minor errors in various functions spotted with
       stricter code checking in R-devel 2.6
	* unescaped "%" in documentation for s109
	* need negative 1 for negative intercept in 
	another part of predict.ideal (for the case where the researcher
	did not supply burn-in; 05/15/2007).

0.91	* added Monte Carlo simulation of pi (simpi)

0.90	* version bump as requested by Achim
	* adding pseudo r-squared stuff
	* adding admit data for ordered probit example
	* adding logLik.polr
	* adding hitmiss method

0.76	* offset and weights arguments have been added to
	  zeroinfl() and hurdle()
	* hurdletest() is a new wrapper for linear.hypothesis()
	  from the "car" package to test for the presence of
	  hurdles.
	* A vignette about count data regression in R has been
	  added (which in particular explains the ideas behind
	  zeroinfl() and hurdle()).
	* correcting/improving documentation of ideal re identification and the normalize option
	* added absentee ballot data from Orley Ashenfelter, used in
	  BASS
	  * John Fox noted an error in odTest (wrong p-value); fixed.

	* minor typo in help for predict.ideal
	* fixed bugs with interactive() in ideal.r

	Boris Shor
	* bug (?) in predict.ideal; after 0.73 change to
	negative intercept, need change in predict.ideal.r to match
	* in zeroinfl(): binomial(link = link) is deprecated, use
		binomial(link = linkstr) instead

0.74	* deprecating meanzero option in ideal, replace with normalize
	* new options for specifying start values in ideal (eigen, random, or user-supplied list);
		this fixes a bug reported by Boris Shor <boris@bshor.com> when working with 
		large rollcall objects
	* removed bad escape "\," in readKH 
		reported by Kurt Hornick <Kurt.Hornik@wu-wien.ac.at>

	* improved tracex
	* fixed bug in dropRollCall (was dropping legis.data attributes)

		updatex.c, updatey.c, and xreg.c

0.72    * fixed error in bioChemists data found by Bettina Grn
  	<gruen@ci.tuwien.ac.at>, variable kids5 was off by 1 unit, now runs
  	from min of zero (no kids).

0.71    * fixed bug in betaHPD discovered by John Bullock
    
0.70    * completely rewritten version of hurdle() and zeroinfl():
            - new formula interface of type y ~ x | z where y ~ x
	      specifies the count model and z the inflation/hurdle
	      regressors.
	    - re-structured returned value, is now more similar to
	      "glm" objects
	    - extended/enhanced extractor functions

0.62    * plot.ideal.1d: better left plot margin, based on max length of
 	  legis.name
	* plot.ideal.2d: inconsistent testing of presence of beta in ideal object
 	  when overlaying cutting planes
	  * plot.ideal.Rd: more examples (but in \dontrun)
	* tracex: bug for 2d ideal objects
	* tracex: 2d, make legend lines heavier for showAll
	* tracex: for R >= 2.4, change par() to par(no.readonly=TRUE) 
	* fixed typo in plot.ideal.Rd

0.61	* fixed bug in summary.ideal found by Keith Poole (8/8/06)
        * documentation of ideal section on Identification changed
	to reflect presence of postProcess function
	* added summary.rollcall into NAMESPACE per request of Jeff
	Lewis
	* no nsl function on Windows, changed readKH to simply call
	readLines with a try-error wrapper per suggestion of
	XP-user Jeff Lewis
        * processing of dropList improved, per suggestion of Jeff
	Lewis
        * cosmetic changes to print.summary.rollcall
	* fixed errors caused by removing sysdata.rda; now utility
	data sets such as stateinfo and partyinfo have to loaded
	via data() in functions inside readKH subfunctions; again,
	Jeff Lewis reported error testing readKH function. 

0.60    * added postProcess
          * added jitter to plot.predict.ideal
          * changed "start" to "burnin" in many function that handle ideal objects
	  * changed checkStart to checkBurnIn in idealHelper.r,
          returns "keep"  (logical vector)
	  * improved documentation for plot1d
	  * dropped plot1d and plot2d from export in NAMESPACE 
          * consolidated some help files, making fewer entries in
          package index etc

	  redundancies, overwriting of function args inside of
	  functions etc
