I have a time series with a one year lag, ar=0.5. The series has some interesting events that disappear when the series is whitened (i.e., fitting an AR process and looking at the residuals). I'd like to remove the autocorrelation in stages to see the effect on the time series. Is there a way to specify the autocorrelation term while fitting an AR process? For instance, given the following:

Given the example: R> (levs <- quantile(volcano,c(0,0.1,0.5,0.9,0.99,1))) 0% 10% 50% 90% 99% 100% 94 100 124 170 189 195 R> levelplot(volcano,at=levs) How can I make the key categorical with the size of the divisions equally spaced in the key? E.g., five equal size rectangles with labels at levs c(100,124,170,189,195)? Apologies if this is obvious. -A R> version

All, I have a fresh build of R 2.8.0 from source on Windows XP using the latest Rtools binary (Rtools29.exe). All appears to be well with the install and make check-all exits cleanly. However, when running R CMD check mypkg the program jumps from checking for non-ASCII to checking the PDF version of the manual: * checking data for non-ASCII characters ... OK * checking PDF version of manual

Lattice experts: Can you think of a way to produce a levelplot as below and then add a histogram of the z variable to the top margin of the plot that would sit on top of the color key? x <- seq(pi/4, 5 * pi, length.out = 100) y <- seq(pi/4, 5 * pi, length.out = 100) r <- as.vector(sqrt(outer(x^2, y^2, "+"))) grid <- expand.grid(x=x, y=y) grid$z <- cos(r^2) *

Hi all, I realize this is asking a lot of lattice, but I want to add a second y axis inside a xyplot and have y1 and y2 have different ranges. Given dat below, I can add a second y axis by overlaying a new plot with par(new=T) and label axis 4 with standard graphics. I've seen an example for doing something similar in xyplot even though Deepayan has indicated that lattice isn't the right

The following is my R script which I am struggling with to assess ICESat data..perhaps it is the ID_min or ID_max that is wrong? I don't know, any help would be greatly appreciated :( # OPTIONS - CHANGE THESE VARIABLES IF NEEDED\par ######################################################################\par \par icesatfile <-

We recently upgraded a test server to samba-4.8.3.... but wonder how to reproduce the legacy behavior with winbind now forced into the picture for better or worse. We specifically do not want any of the whiz-bang capabilities of winbind, just the old familiar mapping of windows usernames to unix usernames. It seems not sufficient to omit winbind settings in smb.conf; i.e., the defaults force the

I am using CentOS 5.0 on my desktop workstation. Are there any deeply compelling reasons to upgrade to version 5.1? I read through the release notes but didn't see any whiz-bang new features. Perhaps some of you can share your personal experience letting us know if you have noticed any differences, etc.

Hi my 12 year old, WIX, is an amazing auto deductive computer whiz. I have to keep up... He is an excellent VB programmer and knows JAVA. I have been told ROR is the future. I want to guide WIX so he can build up a good methodical working knowledge but don''t want him to waste his time on archaic languages that will not be around soon...Should his next step be ROR or would you recommend

I've been trying to figure out for a couple of days why I can't get libvorbis to compile. It has me stumped, though I'm not a whiz at compiling from source. I'm installing on Mac OSX 10.8.2. The relevant commands are: export CC=clang ./configure --prefix=${TARGET} --build=x86_64 --with-ogg-libraries=${TARGET}/lib --with-ogg-includes=${TARGET}/include/ --enable-static

This has ABSOLUTELY nothing to do with R but I was hoping that someone might know because there are obviously a lot of very bright people on this list. Suppose I had a time series of data and at each point in time t, I was calculating x bar + plus minus sigma where x bar was based on a moving window of size n and so was sigma. So, if I was at time t , then x bar t plus minus sigma_t would be

Dear list, This is a bit of an off-topic question, but I'm hoping to get some advice from more experienced people. I've used the website "Web of Science" to manually collect publication counts responding to several keywords as a function of date, since the 1960s. http://apps.isiknowledge.com/RAMore.do?product=UA&search_mode=&SID=P1g9lFJp9 at

hello, I'm having a problem I hope will be easy for someone to explain to me how to fix. I need to migrate from an old server to a new Cisco Smart Storage NAS, which runs some flavor of linux and is Active Directory aware. Using something like Robocopy from the AD server, or rsync or tar from the file server does not preserve user/group identities or directory date stamps (maybe rsync

Hello R community, I am hoping to use a new package that I just installed called "grImport" to import ps images into R for further manipulation using either base graphics or grid. I downloaded the most recent version of Ghostscript from http://www.cs.wisc.edu/~ghost/ that I could find (v.8.56) for Mac OSX. However, I am apparently quite ignorant about how the required

Hi, I cannot do the following: telnet 127.0.0.1 5038 I get connection refused and this is preventing AMP from installing. I had this working when I was using FC3 but I had to upgrade to FC4 for another application. So I am running PHP5, MYSQL 4 with FC4 and asterisk is running (I had this problem before with FC3 and it turned out asterisk was not running) I am using 1.2.0 beta1 Asterisk

Hello-- I'm working my way through setting up an email server for faculty and staff use at the school my wife teaches at, and while not a Linux whiz, am making good progress so far. The school has a NT 4 server which is used for domain authentication, and I am trying to grapple with whether I can achieve the "holly grail" of synchronized passwords between the email server on Linux

I have a small feature request for oggenc: Can a command line option be added to allow the user to set the first serial number to be used for the output ogg stream? This only takes a few lines of code, actually. Rationale: it is quite helpful for debugging other encoders. If oggenc is the "reference" encoder, ensuring that your new whiz-bang encoder has diffable output to oggenc is a

We have a new server running Red Hat 5.2EL. Windows machines can samba to the linux server with no problems, including symbolic links to the www directory. Our Mac OS 10.5.5 machines have a problem with symbolic links to the www directory. On the Mac computers, the symbolic links show up as an alias that cannot be followed. These same MAC computers can samba to the www directory via a symbolic

Dear R experts, Suppose I have a data.frame recording the date and test results of some subjects like this: Name Date results John 01/01/1991 2 John 02/01/1991 3 John 09/0101991 4 Micheal 02/01/1991 4 Micheal 04/01/1991 5 .... How to select the earliest (or latest) test result from all subjects? Thank you. Regards, CH -- "The scientists of today think deeply instead of clearly. One
