similar to: new R-wiki page: display image files

Hello R users I am looking for a package to visualize "relatively planar" directed graphs, with say 100 nodes and specified using an adjacency list. 'Rgraphviz', currently listed on the R-FAQ, seemed suitable (FAQ version 2.9.2009-06-05) But when I looked for the package, I found it had been recently "removed" and was instead directed to archive copies

Hello all This is my first posting for some years. I am back using R again and must say I do like the language (regarding scripting, I also use matlab, perl, and bash). My question involves plotting a Pareto frontier in three dimensions. This is strictly a exercise in visualization, I make no attempt to extract the Pareto set (aka dominating subset) first. EXAMPLE PLOTS For some example

Dear R-help I want to display an image file in a new plot frame. SVG is my preferred format, but I can also consider PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick). By way of background (although not material to this posting), the image file is generated by a call to 'dot' (part of the 'Graphviz' suite) after the required .dot file has been produced using hand-crafted R code.

Hello R users http://cran.r-project.org/doc/manuals/R-intro.html An Introduction to R 6.2 Constructing and modifying lists After a short but successful struggle with nested associative arrays (using named lists), I think the following documentation change might be beneficial.

Hello all, We are pleased to announce the official launch of the R Wiki at http://wiki.r-project.org. Although there are already many sources of R documentation, this R Wiki is a complementary tool, in the sense that "users become R documentation authors", a little bit like "users become developers" for R code.

Hi, I've added several pages of worked solutions for the book Ecological Detective by Hilborn and Mangel to the R-wiki. My hope is that this will be of use to others working through this book without access to a local expert. I am certainly not an expert, local or otherwise. I have posted solutions for chapters 3-6, which includes some really horrible direct translations of the pseudocode

Hello all, This is to announce the creation of R-sig-wiki, a new R SIG (Special Interest Group) mailing list dedicated to the elaboration and maintenance of a R Wiki. You can subscribe at: https://stat.ethz.ch/mailman/listinfo/r-sig-wiki. There is currently a prototype for a new R Wiki at http://www.sciviews.org/_rgui/wiki (temporary address). The main idea is to offer a site where users

I am trying to duplicate the example by Spencer Graves in the wiki, using lmer with the Nozzle data. http://wiki.r-project.org/rwiki/doku.php?id=guides:lmer-tests However the Chisq value and the fitAB values that are calculated are different compared to those in the example. I also get a warning message when I attempt the fitAB. Does anyone have any guidance as to why this might happen and how

Dear list, There is a new rwiki (http://rwiki.sciviews.org) section for 'large scale data' at http://rwiki.sciviews.org/doku.php?id=large_scale_data. This is a massive topic of interest to many. I could use some help filling in the content so that this can develop into a powerful resource for the r-community. I hope you like it, and I hope you are willing to help make it better.

Hola, A lo mejor la solución pasa por ver si Statgraphics puede exportar su fichero a otro formato de cualquiera de los que R sí que puede leer. No sé si además del fichero, tienes acceso a Statgraphics....

For info, I put a little study I did about the byte code compiler and other speedup approaches (but not multicore) on the Rwiki at http://rwiki.sciviews.org/doku.php?id=tips:rqcasestudy which looks at a specific problem, so may not be relevant to everyone. However, one of my reasons for doing it was to document the "how to" a little. JN > > 2. Have you tried the
