Dear All, This is a question to sound out possibilities. I am with the Faculty of Natural and Agricultural Sciences at the University of Western Australia, representing a few of the more statistically minded in the faculty. Essentially, there have been problems in the past with software support, changing over statistical software, and paying lots of money for it. In R you have an advanced

Hi, Have you seen the tcltk package? I believe it is a better option than the one you outline in your message. Why develop a Windows-only GUI? Maybe in a few years your teaching department will give up Windows for Linux (for the reasons you wrote about R: it is free, advanced, and adaptable). There is an article in R News (vol.1, n?3) by Peter Dalgaard on the tcltk package, and the latter

Hi all, I get two different results when using sum() and the switch na.rm. The result is correct when na.rm=FALSE. Linux Redhat 7.3, R version 1.6.1. I've had no luck searching the mail archives, so I was hoping somebody could explain/check this one for me. I will need to apply the function to missing data, simple as it is. Code: x<-matrix(runif(20,0,5)%/%1,4,5) # random matrix

Hi All, I am having trouble installing the sm package, and only the sm package. My box is RedHat 7.3 on a PIV. Readline 4.3-3 is installed (suited for RH 8, but same error under readline 4.2 for RH 7.3), but it seems to be looking for the readline library in the wrong directory. Will installing readline 4.1 do the trick? What else could be done? Rohan Sadler [root at rsadler R]# R CMD

Dear All, There is no advantage of GUI over CLI, IMO. The real issue is the answer to the questions: "What should I do next?" or "What am I allowed to do here?" A "nice" interface, not necessarily GUI, will offer friendly answers: "I was expecting you to do _this_" or "In this situation you are allowed to do _these things_" You see, it's all

Awhile back there was a lengthy discussion regarding R GUI's for teaching, etc. I was wondering if anyone has set up the web page which was to be dedicated to this issue. Philippe Grosjean had the idea of creating a R-GUI projects page. Also, is anyone using a "R-GUI" (for windows) for teaching basic statistics to students doing applied science degrees? Something based perhaps

IIRC, the license stated in the source code of dataplot is rather restrictive. I don't think one is allowed to use the source as can be done with GPL code.

A nice free software with a GUI-interface (which can be linked to R, BTW) is GRETL: http://gretl.sourceforge.net/ . Some people may find it useful for basic stuff.

Have a look at the GUI on dataplot, NIST's plotting software. It is implemented in tcl/tk. The site states it is "public domain software" -- open source? I can't find anything about the license. In any case... http://www.itl.nist.gov/div898/software/dataplot/ Brett A. Magill, Evaluator Research, Assessment, and Evaluation Saint Louis Public Schools Brett.Magill at

Hi all, I wish to implement various landscape ecology measures through R, such as: box counting dimension; twist number statistics; contagion and lacuniarity indices; angular second moment; adjacency measures; dominance indices; etc ... Some of the measures can be applied to shape analysis and classification. Is anyone implementing any of these measures? If so I would like to contribute and

Sorry for entering late in the thread, but I was absent last week. I am developping an alternate GUI for R (and also Splus, Octave, Scilab, Matlab, Ox & Mathematica). The project started 3 years ago, but it is progressing slowly, since I am currently the only developer on the project and had to do it during my extra time. Now, it is going a little faster because I got some time and money

Thanks for the response. I was more specifically looking through the source code for a place where Reaching Definitions was implemented to derive those uses and/or to generate the SSA. To provide some context, as a student I have a project to implement a path infeasibility algorithm to "Sharpen" the results of the Reaching Definitions results in LLVM. Being new to LLVM I wasn't

The immediate uses info provides reaching definitions already, at least while the code is in SSA form. So uh, what more are you looking for? 2009/3/17 Shone Sadler <shone.sadler at gmail.com>: > Hello, > > > I am a newbie to LLVM as well as compilers and I am hoping for some > direction in finding an instance of where a Reaching Definition Analysis is > being implemented

Hello, I am a newbie to LLVM as well as compilers and I am hoping for some direction in finding an instance of where a Reaching Definition Analysis is being implemented within LLVM. I have referenced the sources files, initially hoping to find an explicit ReachingDefinitionAnalysis.cpp file ;-) but with no such luck. Other than that I have found the files SimpleRegisterCoalescing.cpp and the

Hello all, I'm attempting to conduct spatial analysis of trees within a plot. I want to see if the trees are spatially correlated to soil characteristics, say pH, or moisture content. I think one way to do it is with mpl, however, my soil characteristics were not taken at exactly the same locations as my trees and further, the vectors aren't the same length. I'm getting the

Hello, new to the list, first message. This question perhaps might be more appropriate to R-sig-teaching, and I'd be happy to take it there if this is not the right place for it. I am teaching applied statistics at a small liberal arts college with limited resources, and we are currently using SPSS for our courses. Mainly the reason for this, as I understand it, is that this is what

Dear R-Listers, I have spatial data on an equidistant rectangular grid, similar to topographic data. I know that there are quite a few R-packages or base functions that provide nice iso-contours plot, but I don't want a plot, just the smoothed isocontour line of ONE level (e.g. 10 mm). Data sets are large, so it would be preferable if the availability of regular grid data could be exploited,

Hi, I'm sorry for this not being related to R but I think this is a good place to ask. I'm looking for DOE examples(experiments) that can be done at home or in class, such as Paper Helicopter, Paper Towel etc.. I'm thankful for any comment. Thomas [[alternative HTML version deleted]]

Hi R users: I want to know if any of you had used Stata or Statgraphics. What are the advantages and disadvantages with respect to R on the following aspects? 1. Statistical functions or options for advanced experimental design (fractional, mixed models, greco-latin squares, split-plot, etc). 2. Bayesian approach to experimental design. 3. Experimental design planing options. 4. Manuals
