Hello, Attached is a mail regarding question how to insert Date field using ROracle package. I am stuck with this problem and appreciate receiving help from gurus on this list. Code used mainly is: library(ROracle) ### --- Version 0.53 drv <- dbDriver("Oracle") con <- dbConnect( drv, "user/passwd") d <- data.frame(CDATE = "2004-03-10 10:12:00") ps

Dear List, What is the way in R to plot a graph having date time (e.g. format 12/31/2002 13:12) in the x axis and numerical value (e.g. temperature) on the Y-axis ? I could not get 'plot()' to do this as X axis values are non-numeric. 'bwplot()' sorts the date values and thereby changes the order of the dates and of Y. The date/time values have to be shown on the X-axis as tick

R-help list, I ported some R code from MS Windows PC to sun-solaris. Both do queries on the same MySQL database. PC version of R is 1.6.1 and solaris version is 1.6.0. I use RMySQL_0.5-0 (on solaris) and RODBC 1.0-1 on PC to connect to MySQL. The PC version took about 65 mins. to run wheras the Solaris (SunOS 5.7) version took 375 mins. (> 6 hrs). R and RMySQL are resident on the same host

All When I read data into an R variable x using RODBC command: x <- sqlQuery(channel,"select a, b from tabl",as="data frame") and view x, I get 3 columns the first one being the index of the rows in x. What options do I use in sqlQuery so as not have the index in x ? How do I get rid of the index otherwise. For some functions like princomp (and boxplot) for

Greetings list. Pardon the ignorance. I am working on CentOS 5.2. Unfortunately the repo version of Dovecot is 1.0.X. This works fine mind you but it doesn't have ORDEREDSUBJECT Threading support, which I need. I downloaded 2.0.11 and built from source, but now I don't see any Threading support, not even REFERENCES. I looked to see if I was missing a ./configure option but if I am, it

R-help, Could someone in the list write as to what is the R function to perform repeated measures ANOVA and post-hoc tests ?

Happy New Year to all in the list! I am trying to issue an SQL query to a database from R using RODBC (on Windows). The data source file is on my PC hard disk : C:\Program Files\ODBC\sql.dsn The "\" character does not get interpreted properly in R - it is removed from the file-spec string or if I specify "\\" it appears as such with a syntax error in odbcConnect(dsn,

Hi all! First off, if this has been discussed, please point me in that direction. I have searched high and low and really can''t find much info on the subject. We have a large-ish (200gb) UFS file system on a Sun Enterprise 250 that is being shared with samba (lots of files, mostly random IO). OS is Solaris 10u3. Disk set is 7x36gb 10k scsi, 4 internal 3 external. For several

I have a ISO that I have remaster for some custom recovery procedures. I tried using the same rootfs (initrd) that works with kernel 3.1.2 on older hardware, but not newer. So I downloaded the 3.12.1 kernel tree to a Ubuntu 10 server. Builded the 3.12.1 kernel and tried it with the older rootfs. Now the new hardware and old hardware will fire up the network, but when I try and mount.cifs I get a

There''s been another sighting of ZFS on Mac. The latest developer release of Leopard (Mac OS 10.5) has a dialogue box calling out the "Zettabyte File System (ZFS)" as an option. The first publication I saw this is a French website called Mac4Ever - http://mac4ever.com/ news/27485/zettabyte_sur_leopard/ I put up a Babelfish translation at my site, http://storagemojo.com/?

Hi, Sorry to follow up on an old thread, but I am wondering if there has been any work done on, or interest in, increasing the maximum document id beyond a 32bit limit?

Hello, I am working on implementing rsync to replace a server distribution mechanism that currently works like this: 1) process new file on backend server 2) upload file to frontend server using scp or rsync over ssh 3) ssh to frontend server to trigger script #3 is only used in a couple special cases I have this tested and working: 1) (same as above) 2) upload file to frontend server using

I contacted the author of ''lsof'' regarding the missing ZFS support. The command works but fails to display any files that are opened by the process in a ZFS filesystem. He indicates that the required ZFS kernel structure definitions (header files) are not shipped with the OS. He further indicated that he rummaged through the OpenSolaris source tree and the files doesn''t

Hi, using both OpenSSH_2.5.1p1 (compiled myself) and openssh-2.9p1-23.i386.rpm from ftp.suse.com 7.2_update I get the following "leak" : using `scp' I tried to copy a file from a local floppy disk to a remote system, but the disk had an read error and scp didn't get any real data from floppy: turtle koenig > scp /media/floppy/file.c harald:file.c

Hello everyone, This is my first time posting to the list, thanks in advance. I am calculating the smoothed periodogram for the residuals of an AR model that I fit to EEG data. The autocorrelation plot of the residuals shows the series is now approximately white (i.e. ACF = 1 at lag 0, and close to 0 for all other lags). I would like to show that the spectrum of the series is also

Dear All, Is there a function in R which can do a periodogram of Schuster ? Thanks in advance ! Guillaume Blanchet

Hi, Does anyone know the name of the package that includes a function for computing the lomb periodogram on irregular spaced ts data? I saw the package once ~ 1 month ago but cannot find it now ... , Rich

Dear all, I'm trying to finding the fundamental harmonics (ie. peaks in a periodogram) from a time series (extracted from an mp3). For example, if I look at spectrum(fdeaths, spans = c(3,3)) I'd say the fundamental harmonics are about 1, 2, 3.5 and 4.5 - but how can I extract these automatically? (preferably with some heuristic for choosing the smoothing spans too) I'm aware of

Hello - I am currently simulating bivariate AR(1) time series data and have the following line in my code: Px=spec.pgram(ts.union(X,XX),spans=c(?,?)) The spans option is where I enter in the vector containing the Daniell smoother numbers, but I don't know what a Daniell smoother is (hence the question marks). Can somebody please tell me? Is there another option where I can simply enter in
