        Due to interface changes in rpart 3.1-55, the
        bagging function had to be rewritten. Results of previous version are not   
        exactly reproducible.

	fix tests/ipred-segfault	

        0.7-5 (19.12.2003)

	0.7-4 (16.12.2003)

	R-1.9.0 fixes

	0.7-3 (03.11.2003)

	fix documentation bugs found by `codoc'

	0.7-2 (29.10.2003)

	`rpart' is sensitive to compilers / optimization flags:
	the results we compare `ipred's tests with are produced with
	an optimized version of `rpart' (gcc -O2).

	`eigen' in `slda' replaced by `svd'

	0.7-1 (08.08.2003)
	
	adapt to changes in R-devel and lda (package MASS)  
	
	0.7-0 (08.08.2003)

	add namespaces

	0.6-15 (----)

	new argument "getmodels=TRUE" to cv: the returned object has an
        element "models", a list which contains the models for each fold.

	new interface for inclass and adding method inbagg.	

	0.6-14 (13.03.2003)

	clean up bagging.Rd

	0.6-12 (12.03.2003)

	methods for "integer" for the generics "bagging", "cv" and "bootest"

	do not call methods to generics directly, since they may be hidded
	(because not exported: predict.lda)

	0.6-11 (05.03.2003)

	632plus was false when the no-information error rate was less than
	the raw bootstrap estimator (eq. 29 was used instead of eq. 32 in
	Efron & Tibshirani, 1997). Thanks to Ramon Diaz <rdiaz@cnio.es> for
	reporting.

	changed the RNGkind to
		RNGkind("Wichmann-Hill", "Kinderman-Ramage")
	or RNGversion("1.6.2") making the regression tests pass R CMD check
	with R-devel (1.7.0)

	ipred is allowed to import rpart.{anova, class, exp, poisson, 
	matrix} from package rpart, thanks to BDR.
	
	0.6-9 (25.02.2003)

	the terms attribute of data in errorest.data.frame may cause problems
	with some predict methods -> deleted

	0.6-7 (17.02.2003)

	use a formula / data framework in cv and bootest. 

        "model" now deals with the original variable names 
        (and formula) instead  of "y" and "X".

	"model" is now allowed to return a function with newdata argument for
        prediction. This is especially useful for estimating the error of
        both variable selection and model building simultaneously, the
        vignette gives a simple example.

	cv.numeric and bootest.numeric were broken and gave faulty estimates
        of MSE, both problems fixed

	if the maximum of votes for any class is not unique, the class is
        choosen by random in predict.classbagg now. Formerly, the class with
	lowest level was choosen by mistake.

	0.6-6 (06.02.2003)

	fixes required by attached "methods" package 

	0.6-4 (18.12.2002)
	
	R CMD build problems

	0.6-3 (03.12.2002)

	cv in errorest did faultly use all observations for estimating the
	error which lead to over optimistic results

	documentation updates and copyright status added

	0.6-1 (02.10.2002)

	documentation fixes

	documentation updates
	
	0.5-7 (23.09.2002)

	add internal functions irpart and predict.irpart 
        for speeding up standard bagging

	use error.control for the specification of control
	parameters

	cv can be used to caculcate an "honest" prediction for each
        observation

	0.5-6 (12.09.2002)

	code factors in GBSG2 data as factors. Documentation update. Add
        keepX argument to ipredbagg

	0.5-5 (10.09.2002)

	set rpart.control(..., xval=0) by default

	0.5-4 (05.08.2002)

        new documentation for bagging and friends

	0.5-2 (30.07.2002)

	new low-level functions cv and bootest for error rate estimators
        (misclassification, mse, brier score)

	0.5-1 (25.07.2002)

	bagging code completely rewritten

	0.4-6 (27.06.2002)

	out-of-bag error for regression trees fixed.

	use "minsplit = 2" in `rpart.control' passed to `bagging'

	0.4-4 (17.05.2002)

	changes in documentation errorest

	0.4-2 (10.04.2002)

	predict.bagging much faster, OOB much faster

	0.4-1 (08.04.2002)

	bugfix in print.inclass, predict.inclass

	0.4-0 (26.03.2002)
