similar to: Possible bug in POSIX classes for R 2.11.0?

It's two days I try to answer to a mail of Achim Zeileis, the maintainer of strucchange package, using the mail address: zeileis at ci.tuwien.ac.at. I got the following error: ----- The following addresses had permanent fatal errors ----- <zeileis at ci.tuwien.ac.at> (reason: 550 5.7.1 <zeileis at ci.tuwien.ac.at>... Access denied) Can anyone tell me how to reach him?

Hello to all those of the list, I introduce myself: My name is Lester Espinosa Mart?nez, I live in Cienfuegos, a city of Cuba.

I met the Wiki of CentOS thanks for a great one my friends called: Alain Reguera Delgado, and I also collaborated in translating articles of last Wiki of CentOS in Spanish. My

I use a 32 bit machine. For those using 64 bit machines, what is the .Machine$double.xmin for for machines? regards.

Using Achim's d this also works to generate z where FUN is a function used to transform the index column and format is also passed to FUN. z <- read.zoo(d, index = "time", FUN = as.yearqtr, format = "Q%q %Y") On Sun, Jan 28, 2018 at 4:53 PM, Achim Zeileis <Achim.Zeileis at uibk.ac.at> wrote: > On Sun, 28 Jan 2018, phil at philipsmith.ca wrote: > >> I

Dear useRs, the program for the first R user conference useR! 2004 (taking place in Vienna, May 20-22) is now available online at the conference web page: http://www.ci.tuwien.ac.at/Conferences/useR-2004/program.html We received many exciting abstracts about a wide spectrum of applications in which R is used.

I understand that I need to have a (in this case) square matrix with all the data. But the question now is; - can the contourplot not interpolate the missing values or alternatively - I have fit a model to the z data (z = 100 + 0.5x + 0.5y). How can I make from this model a "square" matrix z to make a contour plot? Kind regards, Darius Blaszijk ----- Original Message ----- From:

Hi everyone and Achim, Achim, I appreciate your help about the function "NCOL". When I use "NCOL" instead of "ncol", I can find out the number of columns (number of time series) in the presence of only one time series (one variable, one column). Now I want to know how I can find out the column names of the zoo objects? In case of more than one time series, the

Dear Achim, Thanks for the comment. Here is the publisher's style guideline (AGU) "Because the Internet is dynamic environment and sites may change or move, treat World Wide Web, ftp files, and electronically archived data stored at data centers other than World or National Data Centers as unpublished, i.e., in text only." http://www.agu.org/pubs/AuthorRefSheet.pdf So by this

Hello Ralph, before anything I want to appreciate you vastly, I have the option of editing, but now it show me the following message: "At the moment, the translation for this page is not available.

thank you, achim. I will try chol2inv. sandwich is a very nice package, but let me make some short suggestions. I am not a good econometrician, so I do not know what prewhitening is, and the vignette did not explain it. "?coeftest" did not work after I loaded the library. automatic bandwidth selection can be a good thing, but is not always. as to my own little function, I like the

Thanks for the very detailed explanation. I did not create the series using structure(), that was the result of dump() on an intermediate object created within tsdisagg::ta(), which is where I found the error in the first place. ta() indeed manipulates .Tsp directly, rather than using ts. I guess this is a bug in tsdisagg then. Thanks! -- Andrea Altomani On Sat, Sep 2, 2017 at 12:31 AM

I tried to integrate numerically a function wich is similar to the following: > dummy <- function(x) { exp(-1*x) * dnorm(x) } > dummy(-100) [1] 0 > dummy(-1000) [1] NaN > dummy(-10000) [1] NaN If I choose the lower boundary to be too small integrate causes a segmentation fault: > library(integrate) > integrate(dummy, -100, 0)$value [1] 1.387143 > integrate(dummy, -1000,
