Hello everyone, I am new to R, using version 2.0.1 on a Macintosh running OS X 10.3. I am learning how to export graphics to postscript format using the postscript() function, but R is only writing empty files. Yesterday, postscript() was working for me. Today, I don't know what's wrong. Can somebody suggest some things that might fix this problem? Thanks in advance for you help.

Read R-helpers, I'm relatively new to R and trying to jump in feet first. I've been able to learn a lot from on-line and printed documentation, but here's one question to which I can't find an answer. Well, it's a question with a couple parts. Thanks in advance for any direction (partial or complete) that anyone can provide. I have a data frame with three columns:

Dear R-helpers, New to R, I'm in the middle of a project that I'm using to force me learn R. I'm running into some behavior that I don't understand, and I need some advice. In the last week I've gotten some great advice from the list on visualizing my data, and I was hoping people could help me get over another barrier I've encountered to my progress. Before I

I am fairly new to R. I find it surprising that f <- function(x,a) {x-a} uniroot(f, c(0,1), a=.5) works, but integrate(f, 0, 1, a=.5) gives an error: Error in integrate(f, 0, 1, a = 0.5) : argument 4 matches multiple formal arguments What is the best way of avoiding such surprises? Is there a way of telling integrate() that the 'a' argument is for f()? If I wrote my own function

Hi, I'm trying to use SharpEye2 under Wine: that is a Musical Optical Recognition (musical OCR) program, getting a scanned image and outputting a digital score - look at http://www.visiv.co.uk. It is probably the best such program among the few existing ones and the only thing I miss from Windows. Anyway, the installation goes perfectly, but when I try to run it, a window appears saying

Hi, I've had a stable Samba-run LAN, with some active shares, for several months, with my PC and laptop also gaining access to the Internet through the Samba server. However, this morning, when I booted up my Samba server, I had no LAN--neither my PC nor my laptop could connect to any share. However, both still had access to the Internet. I confirmed that smb, named, winbindd, et al.,

Hi all, I am having problems running a logon script from a Winxp pro client. It appears that the logon script is not being run at all. Win98 runs the script fine, but none of the Winxp pro clients are currently running it. I am running RedHat 7.1 with Samba version 2.2.7-security-rollup-fix. My smb.conf is as follows: [global] netbios name = LOKKI server string = Lokki PDC

Because of the original issue below, it dawned on me to re-compile Samba after the RH9 upgrade from RH7.1. The make fails, and I was hoping someone could shed some light on either/both issues. I'm compiling Samba 2.2.8a with: ./configure --with-smbwrapper --with-pam --with-syslog --with-netatalk --prefix=/var/samba --with-quotas --with-smbmount --with-shadow No errors there, but make fails

Hi all, It was brought to my attention that the front page lists 0.23.3 as the stable release, but that no such release exists. I could have sworn I released this a few weeks ago, but now I can find no evidence of that. I''m going to publish it from the latest commit in the 0.23.x branch as soon as possible (probably in about 12 hours), so if anyone wants to get that last-minute

Hi all, Wondered if there are others in the community using GlusterFS on Google Compute Engine and Kubernetes via Google Container Engine together. We're running glusterfs 3.7.6 on Ubuntu Xenial across 3 GCE nodes. We have a single replicated volume of ~800GB that our pods running in Kubernetes are mounting. We've observed a pattern of soft lockups on our Kubernetes nodes that mount our

I set up a 3.3 gluster volume for another sysadmin and he has added it to his cluster via automount. It seems to work initially but after some time (days) he is now regularly seeing this warning: "Too many levels of symbolic links" $ df: `/share/gl': Too many levels of symbolic links when he tries to traverse the mounted filesystems. I've been using gluster with static mounts

Pam_SMB allows Linux clients to validate their passwords against an NT PDC, so the only thing you have to do is set up the accounts on the Linux side with an '*' in the /etc/passwd entry. This can be done using a list of users: #!/bin/bash for i in `cat myuserlist`; do /usr/sbin/adduser -p '*' $i with various other command line options, such as "-s

Hi listers, Does anybody knows if the function qda for quadratic discriminant analysis provides the coefficients of quadratic discriminants... Well, I find out that for the linear discriminant analysis lda, the fonction provides the coefficients...

Hi, How can I calculate and mark each group centroid in a linear discriminant analysis plot (using ggplot2)? Script: ## originate from http://r.789695.n4.nabble.com/LDA-and-confidence-ellipse-td4671308.html require(MASS) require(ggplot2) iris.lda<-lda(Species ~ Sepal.Length + Sepal.Width + Petal.Length + Petal.Width, data = iris) LD1<-predict(iris.lda)$x[,1]

Dear R users, I am not an R user myself, but someone searching the web for C source code that will do linear discriminant function analysis. The only lead I have been able to locate is that R contains a function called "lda" which is contained in the MASS package. (http://stat.ethz.ch/R-manual/R-devel/library/MASS/html/lda.html) I downloaded the R source file R-1.9.0.tgz, and

I have the Rexcel package. Which of the functions do I want to run a discriminant function analysis? Or, how would I do it in R? Thanks. [[alternative HTML version deleted]]

Greetings everyone, I was wondering if anyone had experience in using fda (flexible discriminant analysis) in the mda package. Specifically, I can run the model but I cant locate/produce much of anything beyond the predicted values and confusion matrix. I've been searching for more examples or documentation but cant seem to locate any specific to the program itself. I need to be able to find
