Re: [R] CRAN (and crantastic) updates this week
I like it. Thanks. 2009/8/24 hadley wickham crana...@gmail.com: Sorry, we had some problems with the initial sending of our weekly digest which resulted in a rather empty email. Here is the correct version: CRAN (and crantastic) updates this week New packages * atm (0.1.0) Charlotte Maia http://crantastic.org/packages/atm An R package for creating additive models with semiparametric predictors, emphasizing term objects, especially (1) implementation of a term class hierarchy, and (2) interpretation and evaluation of term estimates as functions of explanatories. * gnumeric (0.5-1) Karoly Antal http://crantastic.org/packages/gnumeric Read data files readable into R. Can read whole sheet or a range, from several file formats, including the native format of gnumeric. Reading is done by using ssconvert (a file converter utility included in the gnumeric distribution) to convert the requested part to CSV. * KFAS (0.3.1) Jouni Lehtonen http://crantastic.org/packages/KFAS Fast multivariate Kalman filter, smoother, simulation smoother and forecasting. Uses exact diffuse initialisation when distributions of some or all elements of initial state vector are unknown. * munsell (0.1) Charlotte Wickham http://crantastic.org/packages/munsell Functions for exploring and using the Munsell colour system * oosp (0.1.0) Charlotte Maia http://crantastic.org/packages/oosp An R package designed to support object oriented statistical programming, especially by extending S3 capabilities, providing pointer and component objects, and providing basic support for symbolic-numeric statistical programming. * PLIS (1.0) Zhi Wei http://crantastic.org/packages/PLIS PLIS is a multiple testing procedure for testing several groups of hypotheses. Linear dependency is expected from the hypotheses within the same group and is modeled by hidden Markov Models. It is noted that, for PLIS, a smaller p value does not necessarily imply more significance because of dependency among the hypotheses. A typical applicaiton of PLIS is to analyze genome wide association studies datasets, where SNPs from the same chromosome are treated as a group and exhibit strong linear genomic dependency. * rrv (0.0.1) Charlotte Maia http://crantastic.org/packages/rrv An incomplete R package for working with random return variables. The current package provides limited support for formatting money. More features will be added in the future. * ttrTests (1.0) David St John http://crantastic.org/packages/ttrTests Four core functions evaluate the efficacy of a technical trading rule. - Conditional return statistics - Bootstrap resampling statistics - Reality Check for data snooping bias among parameter choices - Robustness, or Persistence, of parameter choices Updated packages AdMit (1-01.03), alr3 (1.1.9), alr3 (1.1.10), cmprskContin (1.1), dataframes2xls (0.4.3), digeR (1.2), doBy (4.0.1), DoE.base (0.7), FrF2 (0.97-1), FrF2 (0.97-3), hdrcde (2.10), HH (2.1-30), JM (0.4-0), memisc (0.95-21), minet (2.0.0), MLDS (0.2-0), monomvn (1.7-3), mrt (0.3), nsRFA (0.6-9), PBSmodelling (2.21), plink (1.2-0), plotrix (2.7), RaschSampler (0.8-2), RCurl (1.0-0), rgdal (0.6-14), RSiena (1.0.5), rtv (0.3.0), sdef (1.1), SIS (0.2), spdep (0.4-36) New reviews --- * sqldf, by m.e.driscoll http://crantastic.org/reviews/26 * SensoMineR, by padmanabhan.vijayan http://crantastic.org/reviews/25 * plyr, by eamani http://crantastic.org/reviews/24 This email provided as a service for the R community by http://crantastic.org.

Re: [R] Removing objects from workspace
It depends. If there are patterns in the names, you can make use of pattern argument of ls(). For example, x1=a;x2=b;x3=c ls(pattern=x[1-2]) [1] x1 x2 ls(pattern=x[^1-2]) [1] x3 # to remove x1-x3 rm(list=ls(pattern=x[1-2])) More generally, if you want to remove all butx,xx,xxx, you can use rm(list=ls()[! ls() %in% c(x,xx,xxx)]) Hope this helps. 2009/8/25 Steven Kang stochastick...@gmail.com: Hi all, I am currently woking with hundreds of objects in workspace and whenever I invoke ls() to observe the names of the objects, there are too much of unnecessary variables. For example, if I only require say 3 or 4 objects from hundreds of objects in workspace, are there any methods that may do the job? I have tried rm(-c(x,xx,xxx)), but no luck..

Re: [R] Compare lm() to glm(family=poisson)
In practices, it is not easy to make such decision. One example is size of social ties in social network study. It is very common to use OLS thought it is count variable rather than normal.

Re: [R] Likelihood Function for Multinomial Logistic Regression and its partial derivatives
You may refer to mlogit for the ordinary multinomial regression. As fas as I know, there are no functions for multilevel multinomial regression. Ronggui 2009/8/2 nikolay12 nikola...@gmail.com: Hi, I would like to apply the L-BFGS optimization algorithm to compute the MLE of a multilevel multinomial Logistic Regression. The likelihood formula for this model has as one of the summands the formula for computing the likelihood of an ordinary (single-level) multinomial logit regression. So I would basically need the R implementation for this formula. The L-BFGS algorithm also requires computing the partial derivatives of that formula in respect to all parameters. I would appreciate if you can point me to existing implementations that can do the above. Nick PS. The long story for the above: My data is as follows: - a vector of observed values (lenght = D) of the dependent multinomial variable each element belonging to one of N levels of that variable - a matrix of corresponding observed values (O x P) of the independent variables (P in total, most of them are binary but also a few are integer-valued) - a vector of current estimates (or starting values) for the Beta coefficients of the independent variables (length = P). This data is available for 4 different pools. The partially-pooled model that I want to compute has as a likelihood function a sum of several elements, one being the classical likelihood function of a multinomial logit regression for each of the 4 pools. This is the same model as in Finkel and Manning Hierarchical Bayesian Domain Adaptation (2009). -- View this message in context: http://www.nabble.com/Likelihood-Function-for-Multinomial-Logistic-Regression-and-its-partial-derivatives-tp24772731p24772731.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. -- HUANG Ronggui, Wincent PhD Candidate Dept of Public and Social Administration City University of Hong Kong Home page: http://asrr.r-forge.r-project.org/rghuang.html __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] RGtk2 help: Show list of column names from dataset and categorize as factor or numeric
I use gWidgetsRGtk2, which provides widgets such as notebook etc. You can start with gWidgetsRGtk2, and if you want to tailor the GUI according to your needs, you can modified them with RGtk2 package. Ronggui 2009/6/4 Harsh singhal...@gmail.com: Hi UseRs, I recently started working with the RGtk2 library. The documentation is comprehensive and I've tried learning from the examples in most Gtk tutorials (which have C code). This is a little problematic, but has helped quite a bit in getting me started. I would like to create a GUI for file selection, which then displays the column names from the selected file, and provides the user with checkboxes with each column name for the user to select. Two columns of check boxes (Factor Type, Numeric Type) and one column of names is what I would like to display. Moreover, I am planning to create a GUI tool that would have tabs in a notebook layout, each tab providing a certain functionality, beginning from basic charting of data, and going on to applying regression models and such on the data. This requires extensive knowledge in components that RGtk2 provides which could be implemented for the task outlined above. I have looked at the omegahat.org examples, but would like to see examples for such simple tasks as to how one could create a drop down list of column names to choose for x axis and another drop down allowing the choice of y axis, etc. Having made the choice to use RGtk2, I would appreciate if users could share their RGtk experience with me.
