This is not about the failure on some platforms, which is an important issue. However, what is below may provide a temporary workaround until the source of the problem is uncovered. FWIW, the problem seems fairly straightforward for most optimizers at my disposal in the R-forge (developmental) version of the optimx package at https://r-forge.r-project.org/projects/optimizer/ I used the code ##

Prof Nash, Prof Galanos Is it possible to use a generic code stub in front of packages that use optimx to improve optimx use or curtail it according to the requirements?

Dear R-Helpers, SAS Institute just mailed out the notice below regarding a survey of people who do data mining. To help keep the survey from becoming biased toward commercial software, I thought it would be good to post it here as well. Cheers, Bob Fourth Annual Data Miner Survey Rexer Analytics has asked statistical and data mining software vendors to forward this survey as a courtesy. (SAS is

Greeting Listserv Readers, At http://r4stats.com/popularity I have added plots, data, and/or discussion of: 1. Scholarly impact of each package across the years 2. The number of subscribers to some of the listservs 3. How popular each package is among Google searches across the years 4. Survey results from a Rexer Analytics poll 5. Survey results from a KDnuggests poll 6. A rudimentary analysis

When connecting with v1, the server logs a message when I exit my login shell: Closing connection to 130.207.167.32 However, when connecting with v2, it only ever logs: Connection closed by remote host. Tracing through the code, it appears that instead of breaking in serverloop.c:server_loop2() at: if (had_channel && !channel_still_open()) {

I just found that trying to specify a DSA identity file with '-i' doesn't work. Although the man page doesn't indicate that this is supported for DSA keys, it also doesn't indicate very clearly that its _not_. Indeed, in ssh.c:main(), the "-i" only increments and sets: options.options.num_identity_files options.identity_files where it would need to modify:

Dear R-Helpers, I've looked high and low for a function that provides frequencies, proportions and cumulative proportions side-by-side. Below is the table I need. Is there a function that already does it?

Greetings, I am pleased to announce the availability of the document, "R for SAS and SPSS Users", at http://oit.utk.edu/scc/RforSAS&SPSSusers.doc . It presents an introductory view of R for people who already know SAS and/or SPSS. Included are 27 programs written in all three languages (i.e. 81 total) so that people can see how R works compared to the other two, task by task. I

Hi All, I'm using the Hmisc summarize function and used list instead of llist to provide the by variables. It generated an error message. Is this a bug, or do I misunderstand how Hmisc works with lists? The program below demonstrates the error message. Thanks, Bob x<-1:8 group <- c(1,1,1,1,2,2,2,2) gender<- c(1,2,1,2,1,2,1,2) mydata<-data.frame(x,group,gender)

I'm running samba 3.0.13 on a debian box, sharing out NFS filesystems from a solaris box. I know, bad idea.. file locking, etc... non-issues at the moment. I've discovered that if I make a share from a local filesystem, the PC's mounting the share see their quota (hard limit, not soft which is another matter) as their capacity and their appropriate free space... this is good.

Hi all, I have some C++ code that I call from my package. In my main C++ loop, I check for user interrupts and return to the R shell after ensuring I've deallocated memory appropriately. This works fine when the code is compiled with gcc+openmp and with icc without openmp, but when I compile with icc and use openmp, the entire R session is immediately terminated when I hit ctrl-C. This

Greetings, I've just put out the latest version of "The Popularity of Data Analysis Software" at http://r4stats.com/popularity. This update includes complete data for 2010, the addition of number of blogs for each software, more coverage of Statistica, and, where possible, measures regarding the implementations of the SAS Language: Carolina and the World Programming System (WPS).

Hi All, I have substantially expanded the table that compares SAS and SPSS add-on modules to somewhat equivalent R packages. This new version is at: http://r4stats.com/add-on-modules and I would very much appreciate any feedback you might have on it. The site http://r4stats.com is the replacement to http://RforSASandSPSSusers.com and includes the support files for both "R for SAS and SPSS

Hi All, I now have programming examples for common research tasks done in R, SAS, SPSS and Stata at http://r4stats.com. The examples fall into the following categories: Data Import & Export Data Management Enhancing Output Graphics, ggplot2 Graphics, Traditional Selecting Variables and Observations Statistics For the graphics examples, I got lazy and only show the R code done two ways.

Hi All, I've been fiddling around with various ways to estimate the popularity of R, SAS, SPSS, Stata, JMP, Minitab, Statistica, Systat, BMDP, S-PLUS, R-PLUS and Revolution R. It's not an easy task. You can see what I've come up with so far at http://r4stats.com/popularity . I'm sure people will have plenty of ideas on how to improve this, so please let me know what you think.
