Dear UseRs!, Everything about UseR! 2010 was terrific! I really mean "everything" - the tutorials, invited talks, kaleidoscope sessions, focus sessions, breakfast, snacks, lunch, conference dinner, shuttle services, and the participants. The organization was fabulous. NIST were gracious hosts, and provided top notch facilities. The rousing speech by Antonio Possolo, who is the chief

The abstract submission deadline for the R Users Conference, useR! 2010, is just one month away. Submission deadline: 2010-03-01 Early registration will also close on 2010-03-01. Now is the perfect time to prepare an abstract presenting innovations or exciting applications of R. The call for abstracts along with the link for submission is available at:

Dear R useRs, I have a problem with nls.lm function of minpackl.lm package. I need to fit the Van Genuchten Model to a set of data of Theta and hydraulic conductivity with nls.lm function of minpack.lm package. For the first fit, the parameter estimates keep changing even after 1000 iterations (Th) and I have a following error message for fit of hydraulic conductivity (k); Reason for

Dear All, We are happy to announce the release of the new version of DEoptim (version 2.0-0) which is now available from CRAN. The DEoptim package [3] performs Differential Evolution (DE) minimization, a genetic algorithm-based optimization technique [2,3]. This allows robust minimization over a continuous (bounded or not) domain. The new DEoptim function calls a C implementation of the DE

Dear All, A short-term (approx. 6-month) postdoctoral or scientific programmer position is available in a computational sciences project in Amsterdam. The title is dependent on experience. The starting date should be before the end of 2008, and applicants must be a citizen of a member state of the European Union. The ideal applicant would: o be an experienced R programmer o have experience in

Dear All, A new task view "ChemPhys" on chemometrics and computational physics is available on CRAN (http://cran.r-project.org/web/views/ChemPhys.html). It describes packages and functions that are of use in modeling chemical/physical systems. Suggestions and comments regarding this task view are welcome. If you think a new category, package or function should be added, please mail.

A new package 'nnls' is now available on CRAN. The package provides an R interface to the Lawson-Hanson NNLS algorithm for non-negative least squares that solves the least squares problem A x = b with the constraint x >= 0. The Lawson-Hanson NNLS algorithm was published in Lawson CL, Hanson RJ (1974). Solving Least Squares Problems. Prentice Hall, Englewood Cliffs, NJ. Lawson CL,

Special Volume on Spectroscopy and Chemometrics in R Guest Edited by Katharine M. Mullen and Ivo H.M. van Stokkum 11 contributions, with software packages and examples Similar volumes on R in Psychometrics (guest edited by Jan de Leeuw) and R in Political Methodology (guest edited by Micah Altman and Simon Jackman) are close to being finished. Additional volumes are being worked on. Proposals

We are pleased to announce that the R user conference useR! 2014 is scheduled for July 1-3, 2014, and will take place at the University of California, Los Angeles. As for the predecessor conferences, the program will consist of two parts: invited lectures and user-contributed sessions (abstract submission will be available in due course). Prior to the conference, there will be tutorials on

A new package 'bvls' is available on CRAN. The package provides an R interface to the Stark-Parker algorithm for bounded-variable least squares (BVLS) that solves A x = b with the constraint l <= x <= u under least squares criteria, where l,x,u \in R^n, b \in R^m and A is an m \times n matrix. The Stark-Parker BVLS algorithm was published in Stark PB, Parker RL (1995).

Participants in the R User Conference, useR! 2010, July 21-23, (http://R-project.org/useR-2010) will each receive a t-shirt, thanks to the sponsorship of Mango Solutions (http://www.mango-solutions.com/). This email is a call for designs for the front of the t-shirt. The design should be made using a single color of your choice. The design should be in the form of a high-resolution (at least

Mother always told me that there'd be days like this. She just didn't tell me that they go on for weeks. OK - John's book suggests that we're not complete in this arena here...Yeah, I bought the Samba 3 How-to-guide - Borders/Phoenix had 3 on the shelf (now 2) - and also an LDAP book for reference. It's been a fun weekend ;-) problemo... # smbpasswd -x -i MULLEN
