Hello R experts, I have two questions related to the nnls library (http://www.inside-r.org/packages/cran/nnls), and more broadly to linear regression with positive coefficients. Sample code is below the Qs. Q1: Regular regression (with lm) gives me the significance of each variable. How do I get variable significance with nnls? If there's no ready function, any easy way to manually derive

Greetings again, I am experiencing a lockup when ghost casting about 1 out of 5 client machines locks up. I don't recall if I was having this issue when I was using 3com pxe menus or not. I was wondering if the issue I am seeing could be caused by pxelinux since it basically is loading a Linux kernel then booting a MSDos.imz file. I cannot find any errors from the ghostcast side or the

Seems like my day for Rails posts... :) OK. I''ve started using Swtichtower to help with deploying changes to my production rails apps. Unfortunately I''ve come accros an inconsistency that I can''t quite figure out. It''s about the PATH env var under Bash. I''ve created a task that just does a: run "env", to show what I''m seeing:

Greetings, I have run into a rather bizarre problem that is beyond my meager skills to debug so I am turning to the collective wisdom of this list. Here are the facts: 2 SGI machines (alpha running IRIX 6.5.15 & beta running 6.5.14) running openssh-3.4p1. ssh was built on each machine using the same configuration and were working fine. I upgraded the OS on alpha to 6.5.17 and ran into

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

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

My apologies if this is not the appropriate forum for this but I have posted twice to the ssh security list and have not received any replies. I would appreciated any help that anyone can offer. TIA ------- Ok, this is a repost from awhile back to which I received no replies. Originally, I was dealing with 3.4p1 but I am running into the same problem now with 3.5p1. I would greatly

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 -

Is a library available for R that includes algorithms for something called "archetypal analysis," a method similar to principal components analysis that is designed to find "archetypes" or "pure types" from multidimensional data. I have contacted one of the authors who has written about archetypal analysis but thought I'd check here also. Thanks. Loren

Hello - The final schedule for the Asterisk birds-of-a-feather meeting (as an adjunct to the VON conference) in Boston looks like this: Tuesday, September 23rd at 8:15 at VinnyT's of Boston near the Hynes Convention Center. We'll try to get a corner booth in the "downstairs room", and look for the guy wearing the blue button-down shirt with VON logos on the breast pocket

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

Hello, I am running into some strange (to me) behavior trying to upgrade from 3.6.1p2 to 3.8p1 on Solaris 8. All of my machines are running 3.6.1p2 (Linux boxes have had RH errata applied). When I ssh with my AFS account name from any of them to the Solaris 8 box running 3.6.1p2, it responds with "afsuser at machine's password:". Once the password is given, I am logged in just

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
