similar to: is there a way to find the best ARIMA model

I tried to find a function called "bestARIMA" but it did not show up... even on google it does not show up often: I've only found the following link with "bestARIMA" in it: http://sirio.stat.unipd.it/files/ts02-03/tsR.pdf but where is the package and the function in R?

Dear R-Users, How can I compute simple moving averages from a time series in R? Note that I do not want to estimate a MA model, just compute the MA's given a lenght (as excel does).

Hi guys, I have noticed that when I specify an "admin users" clause in a printer share, all print jobs get spooled as root, and not as the user which sent the job. Since administrative options are related to pausing/deleting jobs from the queue and not spooling them, I think it would be very nice that, even when a user has admin privilege over a printer share, the job appeared as being

Hello, does anyone know how I would go about getting R to connect to OpenOffice's Base program (OOo's version of MS Access) such that I can retrieve data from the database and perform calculations and data analysis? I'm totally new to R and Base and I've looked at some documentation, but found only examples for R connecting to PostgreSQL and MySQL, but nothing for OOo's Base

Hello, I've got a problem with a PHP script, in which I call the system function (to call another processes). The call is : system("R --slave --vanilla < path/to/source/source.R"); if in this R file, I've got the lines: pdf(file="/path/to/file/file.pdf") commands dev.off() the pdf file is perfectly created but if I change the lines to:

Hi all R-Experts, I'm facing one problem in yahoo data downloading. I'm suing Windows XP, R 2.2.0, and i'm using yahoo.get.hist.quote function to download data. I need 500 companies of S&P index daily 'closing price' data for last ten years. My questions are: 1) I have all the ticker names of S&P 500 companies in a .csv format. I'm reading those names in R and

Hello R help I have been trying to use Rob Hyndman's monotonically increasing spline function. But like another user or two seem have a problem with a missing DLL (namely "spline_coef"). None of the previous help postings seemed to have any solutions to this problem. As per a Ripley suggestion I have deleted all previous versions of R and reinstalled R 2.7.0 and the problem

I'm trying to fit a mixed-effects model of the form Y = a + bX + cZ + e where X are fixed effects and Z are random. i.e., c is a vector of random coefficients with mean 0. There is no "grouping" variable such as would be used with longitudinal data. Can the nlme package handle this sort of thing? Although it is a simpler model than would be used with grouped data, I can't seem

I am trying to get a dll compiled for use with dyn.load. I use R.1.7.1 under Windows. I have tried the following trivial example based on the "Writing R extensions" manual. rtest.h -------- class X { public: X (); ~X (); void Give7(double*); }; class Y { public: Y (); ~Y (); }; rtest.cpp --------- #include <iostream.h> #include "rtest.h" static Y y;

I've been successfully using a dll via dyn.load() with R1.6.0 for Windows, but when I try it under R1.6.1 it manages to crash the program completely. Has there been a change in how R1.6.1 handles dynamic loading? I couldn't spot any such changes in the documentation. This problem occurred on two different machines, and both run the code under R1.6.0 without a problem. Rob Hyndman

We are researchers from different parts of the world and conducted a study on the world’s biggest bogus computer science conference WORLDCOMP ( http://sites.google.com/site/worlddump1 ) organized by Prof. Hamid Arabnia from University of Georgia, USA. We submitted a fake paper to WORLDCOMP 2011 and again (the same paper with a modified title) to WORLDCOMP 2012. This paper had numerous

Has anyone got a function for smooth monotonic interpolation of a univariate function? I'm after something like the NAG function PCHIM which does monotonic Hermite interpolation. Alternatively, montononic cubic spline interpolation. Please reply directly.

Hi, I had some Java code that worked with SJava 0.65 under R 1.8.*. I'm trying to get it to work with R 2.0.0. My JVM is Sun 1.5.0 (running on Fedora Core 2) I downloaded and installed SJava 0.65 in my personal directory using R CMD INSTALL SJava-0.65.tar.gz -l ~/src/Rlibrary and before starting R I sourced RJava.bsh. However after loading the SJava library if do javaConfig() I get

I'm not sure who is responsible for quantile(), but I assume they read this list. Ivan Frohne and I have produced a revision of the quantile.default() function which enables the computation of alternative sample quantile definitions. The code and .Rd file are attached. This enables the user to produce quantiles that are equivalent to those in various statistics package. There is a type

Hi all, I'm trying to do a simple curve fit and coming up with some interesting results I would like to get comment on. So as shown below, tsR is my explanatory and response is... well... my response. This same data in gnumeric gets fitted with the curve "response=10078.4 + 1358.67 * ln (explanatory - 2009.07) So I'm using nls with the start values supplied by gnumeric. in

I read Ben Rockwood''s blog post about Thumpers and SMART (http://cuddletech.com/blog/pivot/entry.php?id=993). Will the SUNWhd package only work on a Thumper? Can I use this on my snv_101 system with AMD 64 bit processor and nVidia SATA?

I quoted the relevant part of the documentation for you. Have you actually try to read what it says? Sure, you don't get any error, but have you checked whether any bootstrapping was actually done? Most of those functions are generics, thus having the "..." argument that can take anything. Doesn't mean they will be used. See if the following helps: > x <- 1:10 >

Intel has VBIOS updates available that end-users typically cannot use unless their vendor includes it in a system BIOS update. The only exception is being able to use a DOS TSR (terminate and stay resident) executable, which doesn?t work e.g. in NT-based Windows. However, I do not know if this also applies to Linux (and that may be a question to ask elsewhere). However, regarding MEMDISK, would it

Hello, I am a bit over my head on this issue. My colleagues and I are running R off of our server. We all have admin rights and prior to yesterday we all had our own libraries. Our main system administrator advised us that we should have a shared library. So, I am trying to do this. I have downloaded the latest version of R and installed it on the main drive of our server in the "Program
