On FC10 with openmpi and mpich2 installed, the command "R CMD INSTALL Rmpi_0.5-7.tar.gz --configure-args=--with-mpi=/usr/lib64/openmpi" (or /usr/lib64/mpich2) fails with the error ''cannot find mpi.h". Doing a (s)locate indicates no header file labeled as such. Would appreciate any trailheads. TIA, V. -- Vince Fulco, CFA, CAIA 612.424.5477 (universal) vfulco1 at

I''m struggling to get switchtower working, and from other posts about it I know it has something to do with ruby binding to open ssl.

Hi all, I hope you are doing well? I?m currently using the lm() function from the package stats to fit linear multifactor regressions. Unfortunately, I didn?t yet find a way to fit linear multifactor regressions with constraint coefficients? I would like the slope coefficients to be all inside an interval, let?s say, between 0 and 1. Further, if possible, the slope coefficients should add up to

Ok, and if I would just like to force my slope coefficients to be inside an interval, let's say, between 0 and 1? Is there a way in R to formulate such a constraint regression?

If the slope coefficients sum to a constant, the regressors are dependent and so a unique solution is impossible (an infinity of solutions would result). So I think you have something going on that you don't understand and should consult a local statistician to help you formulate your problem appropriately.

Hi Gabor, Thanks a lot for your help! I tried to implement your nonlinear least squares solver on my data set. I was just wondering about the argument start. If I would like to force all my coefficients to be inside an interval, let?s say, between 0 and 1, what kind of starting values are normally recommended for the start argument (e.g. Using a 4 factor model with b1, b2, b3 and b4, I tried

Have you tried web searching on " R constrained linear regression" or similar. There seemed to be resources related to your issues when I looked. You might also search on rseek.org . There are apparently several packages that do regression with constraints, but I don't know if they fit your situation. Cheers, Bert Bert Gunter "The trouble with having an open mind is that

A few weeks back I had tried to install CentOS on my old AMD 5x6x (equiv to P75 performance) with plans to use it as my firewall and router. Because there were some problems relating to RPM compile architecture (apparently), I posted and Bryan suggested IPCop, even at peril to his life on these lists ;-) according to him. ;-) ;-) Just wanted to tell him thanks, it's worked out well. Had

The nls2 package can be used to get starting values.

This is a quadratic programming problem that you can solve using either a quadratic programming solver with constraints or a general nonlinear solver with constraints. See https://cran.r-project.org/web/views/Optimization.html for more info on what is available. Here is an example using a nonlinear least squares solver and non-negative bound constraints. The constraint that the coefficients sum

Hi All, I am learning R and having a little trouble with the usage and proper definitions of data.frames vs. matrix vs vectors. I have read many R tutorials, and looked over ump-teen 'cheat' sheets and have found that no one has articulated a really good definition of the differences between 'data.frames', 'matrix', and 'arrays' and even 'factors'. I

While using the linux bridge module in 2.6.10, the kernel seems to munge the source IP address of broadcast UDP packets if they come from "0.0.0.1", and sticks on an address of the linux host. I humbly submit that re-writing the source address of packets is not proper behavior for a bridge, even if those source addresses are not traditionally valid. Sure, 0.0.0.1 isn't a valid

Does anyone know if there is a function available which can format any entered number as words? eg: ''1234'' would be ''One Thousand Two Hundred and Thirty Four'' In the past, I would have said this is a tall order, but from what I''ve seen with playing with rails for a short time, I don''t know what to expect. :) Thanks for any help, Damien

Hello all, First, happy to see the new release of WINE 20050111 for FreeBSD (and previous 20041201) I obtained and compiled the latest version for my standard FreeBSD 5.3 install. ?

Dear all, I have a data matrix with 7 independent variables, and each of them is a trinary variable ( - 1, 0 , 1), and I would like to know what kinds of R package or method I should use to perform the clustering.

I've been trough the R documentation for about half an hour and it's not clear to me how to do this: I need to format to character a series of integers from 1 to 1000, and I like them to look like "0001" "0002", "0059", "0123" and so on.

Hi all, Here is something that i still haven''t understood. When installing PRIO, it creates 3 "classes" with priority level according to the TOS.
