Hello: The development version of Ecdat on R-Forge contains a vignette in which optim(?, method=?L-BFGS-B?) stops with an error message while violating the lower bound. To see all the details, try the following: install.packages("Ecdat", repos="http://R-Forge.R-project.org") Then do "help(pac=Ecdat)" -> "User guides, package

Hi, Currently I am trying to solve a minimization problem using optim as method Nelder-Mead. However, Neldel-Mead needs many iterations until it finally converges. I have set $control.trace and $control.report such that I can see the value of the function at each iteration. I do see that I set the convergence criteria to strict in the sense that the function value does not change much. However,

Hej, Calling newuoa (from the minqa package) makes R crash when the package rgl is loaded first. This however only on certain selected data. The data used for testing (saved to 'bugs.R'): xvals = c(1,2,4,5,7,8,9,10,11,12,14,15,16,18,19,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36) yvals =

Subject: Non-GPL packages for R Packages that are not licensed in a way that permits re-distribution on CRAN are frequently a source of comment and concern on R-help and other lists. A good example of this problem is the Rdonlp2 package that has caused a lot of annoyance for a number of optimization users in R. They are also an issue for efforts like Dirk Eddelbuettel's cran2deb. There

Bug: all .out files get rebuilt every make. This is silly, and breaks make install if root cannot write to your build dir. Fix: add dependancy check sop .out files only get rebuilt if the source file changes FixBug: if any source file gets changed, all .out files get rebuilt. This is because man pages and config files both get .out extensions but get created differently. It's

I needed a symbolic and algebraic computation software. The best solution I've found so far is maxima computer algebra system. I was wondering if there is any R package that has similar features as maxima's or somebody could point me to reference manuals on how to use R for this purpose. Thanks, Angel

I'm planning to try to use Mike Powell's new BOBYQA optimization routine to see if it is a good candidate to eventually replace Nelder-Mead as the optim() default. (Don't panic -- this won't happen quickly.) Mike writes f77 code. After some chasing about, I've realized that because optimization codes need to call the objective function written in R, they need to use a language

Hello, I'm pleased to become a list member. Excuse me! I need your help. My problem is that: We have a Samba server running on Linux, this is a PDC in our LAN. There is a share in the server with full access for any user (that's the idea), but when a user writtes a file in the share, he/she becomes the new file owner, and the write permission is exclusively for him/her, consequently

Hi, I would also be in favor of a stronger stance on licenses. In industry, where we can really get in big trouble for violating a license, we often maintain internal repositories, or need to be careful about filtering what is used from CRAN. I think that is should really be a requirement the package authors commit to stating what the restrictions are on their packages. Nicholas On 10

Dear R-er, For a non-linear optimisation, I used optim() with BFGS method but it stopped regularly before to reach a true mimimum. It was not a problem with limit of iterations, just a local minimum. I was able sometimes to reach better minimum using several rounds of optim(). Then I moved to optimx() to do the different optim rounds automatically using "Nelder-Mead" and

>From time to time people request symbolic computations beyond what D() and deriv() etc can provide. A brief look at the internet shows that there are many more or less developed computer algebra packages freely available. Therefore, I wondered if it would be an idea to try to 'integrate' one of these packages in R, which I guess can be done in more or less elegant ways... I do not know

The attached unified diff fixes configure so that all --with-libfoo options are allowed to be --with-libfoo=PATH. If the option is specified with a PATH, only that PATH is searched for the library. If it is specified as =yes or with no argument, it tries without modifying anything, and then tries looking in /usr/local. The SunOS5 targets no longer add /usr/local to include or library paths

Hi! I'm a Linux beginner, and I installed Suse Linux 8.2 to my computer. I installed Samba too... Then I configured it... I wrote in to the web browser: http://localhost:901. Swat came in, and I configured things what I read in a Samba book. Then I started smbd, and nmbd. Smbd worked, but nmbd won't start! I made a probe to write in the "smbd -D" command. It worked... But by

Hi all, This is my first post, I hope you will help me. I've some data to present with histograms. I have few values with almost 99% of the frequencies (thousands) and some other values with low frequencies (below one hundred) that I want to emphasize. I think if I could present the logarithms of the frequencies, these could be presented in a more convenient way, but I don't know how
