similar to: Archetypal Analysis in R

I previously asked a question about performing archetypal analyis in R. In addition to the responses I received from r-help, the author sent me some S code to peform the analysis. With the author's permission, I ported the S code to R using two excellent sets of instructions: (1) From the FAQ - 5.5 How can I create an R package? (2) Thomas Lumley's instructions on porting S to R -

Hi, I'm new to R. I'm trying to install R-0.64.0 on FreeBSD 2.2.8 (also new to FreeBSD). First, I run ./configure and then make. Make gives me an error message because it cannot find "eda.so" when trying to link it with line.o and smooth.o (see output below). I would appreciate it if somone could help me to fix this error. Thanks. Loren AFTER RUNNING CONFIGURE: R is now

Hi Sir/Madam, I'm a researcher in university of Guelph, Canada and now considering using R to do some data analysis. I'm wondering whether there is a library available in R that includes algorithms for "archetypal analysis"? This is a method quite similar to principal components analysis that is designed to find "archetypes" or "pure types" from

Thanks for your help Duncan. Your last comment helped me to figure out what FreeBSD was doing differently than Linux/Solaris. This fix worked on a machine with Python 2.1, R 1.3.1 and FreeBSD 4.1. Here are the details: The pthreads fix: I added '-lc_r' to the PKG_LIBS definition in src/Makevars.in. The FreeBSD 'man pthread' page suggests that adding -pthread to the gcc statement

I'd like to use the resources() function described on p. 151-152 of S Programming by Venables and Ripley (2000), but I don't have access to S and don't know whether R's memory functions (e.g., gc()) can be used instead of mem.tally.reset() and mem.tally.report(). In order to implement the resources() function in R, should I look for the C source for these S functions and wrap them

I've used R for a couple of years on FreeBSD with few problems. Recently, a couple of the contributed packages seem to have difficulty finding symbols in the shared libraries. Currently, I'm running R 1.3.1 on FreeBSD 4.4. I've tried setting LD_LIBRARY_PATH to /usr/local/lib and some other things. The packages I've had trouble with are: Matrix 0.3.15 RODBC 0.8.3 RSPython 0.3

Does anyone know how to graph a line according to a specified equation? I'd like to plot the following hyperbola: Y=139.35/(1+(0.174*X)) I know there's a way to do this, but I'm having a ridiculous time trying to remember how. Thanks! Kyle H.

Moin, I wrote a small backup script that use rsync: r5backup (http://sourceforge.net/projects/r5backup/). It backup dozen of unix machines for many people. But when I try to backup /var/lib/zope2.9 I get an error 11. It does not matter if zope is running or not. I can't see an error meassge in the (verbose) logfile: [client] parse_filter_file(/etc/r5backup/profiles/boulder.exclude,0,3)

Hi all, I've noticed that many computational neuroscience research groups use MATLAB. While it's possible that MATLAB may have some features unavailable in R, I suspect that this may instead simply be a case of costly tradition, where researchers were taught MATLAB as students and pay for it as researchers because it's all they know. I'd like to attempt to break the cycle by

Hi everybody, just another Google Summer of Code project idea. Best, Manuel. ---------------------------------------------------------------------- cranlab -- "You can't control what you can't measure" [0] Mentor: Manuel J. A. Eugster Summary: The aim of this project is the (1) implementation of software metrics to analyze R packages and (2) the creation of a CRAN

Dear R-list, I am having trouble getting the Plot function to set the tick marks the way I want, and I am not sure what I am doing wrong. Below is the code that I wrote, and I am not sure why it doesn't work. p is a vector of length 2198, containing numbers between 0 and 240. q is a vector of ones, the same length as p. I want the x-axis to have tick marks every 30 min and I want the

After several months of development, we are proud to announce you the first public release of Archetype JavaScript Framework (License MIT, version 0.1)! Archetype is a JavaScript framework.

Hello Syslinux users, I just wanted to introduce myself as Loren Hudson, and I work for The Tuck School of Business at Dartmouth College as a System Administrator. I have been using 3com PXE menu's for 3 years now and recently upgraded myself to pushing a pxelinux menu instead of the dull 3com menu's. I will post back with an issue I been having in a separate e-mail. This email is mainly

I am trying to execute a program under rh 7.2 with an application switch '/'. Though the documentation states this is possible I have been unable to execute with success. I have tried many escape variations for the slash but that has not worked either. Any thoughts? Thanks! Loren

Hi everyone, I'm a newbie to R and to linear mixed effects modeling, so please have mercy :-) Just wanted to check, whether what I'm doing is alright. I've collected data concerning tonotopic organization of the auditory cortex in humans, and I have approximately 1400-1800 data/time points per person (13 in total). Observations were made how the focus of neuronal activity changed

Dear R-help subscribers, Can some one please help me figure out how to write code that will allow me to use a for loop to scan a number of files one by one, and then save a summary of each file as the for loop progresses. For example I have 24 files named a1 through a24, and I want to do something like: results<-numeric(24) for (i in 1:24) { p<-scan("ai.txt") # where the i

Does anyone have any suggestions for how to test for violation of the sphericity assumption and apply the Huynh-Feldt correction to a repeated-measure model? My model follows the format below: Rep.anova=aov(Y~X1*X2+Error(Subject/(X1*X2),data=DataFile)) I've already looked at the explanations aov() and Error() in Baron's “Notes on the use of R for psychology experiments and

I am trying to get ntlm_auth working for Authentication against the local Samba PDC which is running on the same computer. I am using samba 3.0.28a on Ubuntu 8.04.1. smbd, nmbd, and winbindd are running and Windows clients have no trouble logging into the domain. Running ntlm_auth --username=myusername reports No logon servers. I ran the command as root and according to strace, it looks like

I am looking for some good tools to manage Samba users in LDAP. It looks like there are several good tools mentioned on the Samba Wiki, but I am concerned mostly with the proper addition of new users to LDAP, in particular, generating unique SIDs. smbldap-useradd, for example, generates the SIDs for primary user and group based off of a simple formula based on the UID and GID, whereas Samba

I'm seeing timestamps off one hour in Windows 200 and XP clients that were modified earlier this year before the +1 hour daylight savings time. They show correctly when views from the Ubuntu Linux Server running Samba 3.2.3-1ubuntu3.8. As a test, I created three files in Linux at 00:13, 01:13, and 03:13. I could not create a file during 2 am as that time does not exist in the local
