Yes, oversight, I think ;-) Added to the devel-version of zoo. I'll try to get it out to CRAN in the next days. Z > Thanks > > Tobias > > > > library(zoo) > > x.Date

To the R development team; I found an unusual behavior in zoo when I upgraded to R 2.11.0 - it abruptly terminated when I performed certain operations on large zoo objects. I sent an e-mail to Achim Zeileis and he said this was a potential bug that I should report to the R development team. The details are given below in the thread below. Basically, I can crash R with this code: library(zoo)

Dear useRs, the strucchange package for testing for structural change has been updated: the current version is 1.2-4. The most significant additions were two functions gefp() and efpFunctional(). gefp() implements a class of generalized M-fluctuation tests for testing for parameter instability or structural change in general parametric models including generalized linear models (GLMs).

The original subject line is false. It *does* reposition, but `origin' was being ignored, so your request was to reposition to the beginning of the file, and that is what happened. This was already fixed in R-patched: from NEWS there: o seek() on file connections was ignoring the `origin' argument. It's always worth looking at the current patched version. On Tue, 29 Jan 2002

Thanks for the advice, folks! Shravan Vasishth <vasishth at ling.ohio-state.edu> Try pico. There's no substitute for/comparison with emacs, though, IMHO. but just to be sure: you don't have to have ESS to use (x)emacs for editing R scripts. Sven Garbade <garbade at psy.uni-muenchen.de> ESS can be installed via rpm on Mandrake. baron at cattell.psych.upenn.edu (Jonathan

Dear R users, there is a new version of the package `lmtest' for testing linear regression models on CRAN. Except for a couple of minor bug fixes, there are essentially these new features: o added Breusch-Godfrey test for serial correlation (thanks to David M. Mitchell who provided the initial version of the code for bgtest) o new data sets: mandible measurements in fetuses,

There is a new package in the devel-section of CRAN called 'strucchange' providing functions for testing on structural change in linear regression relationships. It features tests/methods from the generalized fluctuation test framework as well as from the F test (Chow test) framework. This includes methods to fit, plot and test fluctuation processes (e.g., CUSUM, MOSUM, recursive/moving

I appreciate to Roger Koenker, Achim Zeileis and Vito Muggeo for their informative answers. Listed below is unedited replies I got followed by the question I posted. Kyong 1. Roger Koenker: You might try rqss() in the quantreg package. It gives piecewise linear fits for a nonparametric form of median regression using total variation of the derivative of the fitted function as a penalty

Dear useRs, here is the announcement for the next "new" package: sandwich 0.1-3. sandwich provides heteroskedasticity (and autocorrelation) consistent covariance matrix estimators (also called HC and HAC estimators). The former are implemented in the function vcovHC() (which was available in strucchange before - and independently in hccm() in John Fox's car package). And the

Dear useRs, I used the summer months to work on all of my packages, and so this is the first of a sequence of announcements of "new" or updated packages. The "new" packages are new in the sense that previous versions had been on CRAN for some months but hadn't been announced to the R community via this list until now. All packages are available from the CRAN master site

Dear useRs, yet another "new" package: zoo 0.2-0. zoo provides a simple S3 class and methods for totally ordered indexed observations such as irregular time series. Although there are other packages for irregular time series available on CRAN (Giles Heywood's its package and irts() in Adrian Trapletti's tseries package) I wrote this package because I needed something which

Dear useRs, my last announcement is an update of the ineq package for measuring inequality, concentration and poverty. The current version is now 0.2-4. Thanks to suggestions from Rein Halbersma the Pen() function for plotting Pen's parade was improved and now allows for much more flexibility. See the help page for examples. Best wishes, Z ------------- Package: ineq Version: 0.2-4 Date:
