Hi, I am a Newbie for R. I just installed R-base on my notebook with openSuSE 11. However, I always got compilation errors in installing add-on packages. For example, when installing "igraph" I got the following error: ___________________________________________________________________ * Installing *source* package 'igraph' ... checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we...

Hello, I'm having trouble getting the igraph package to load on Solaris. I can get igraph to compile and install from a local directory without issues using simply "R CMD INSTALL igraph", however "library(igraph)" from within R gives the following errors: Error in dyn.load(x, as.logical(local), as.logical(now)) :...

Been and R-user for about 5 years now in an industrial setting, and always find the mailing list most helpful. I have run into problem compiling igraph on R. I have contacted the maintainer of igraph, and he has determined that it is not an igraph problem. System is FreeBSD 7.2, R-2.10.1 [also have a sandbox machine running FreeBSD 7.3, R-2.11]. Both machines fail the installation of igraph. Here is the error: Error in dyn.load(file, DLLpath =...

Hi R users, I got warning messages when installing the package, and I pasted the messages below. I checked updates that my R-studio is already the newest version. I don't know how to solve the problem.

I have R 2.15.0 running under Windows 7. I installed the igraph 0.5.4 package from a zip file. When I attempt to load igraph using "library(igraph)", I get the error package igraph is not installed for arch=x64.  When I repeat this using the 32-bit version of R, I get the same basic error but with "arch=i386" instead of x64.

Hi, I would like to be able to develop a function to plot an igraph object with lattice (trellis type displays will be usefull for grouping etc). Anyway, I mostly feeble Igraph requires that you convert two columns of data two an igraph object and to be able to plot the graph...I have tried a very, very simplistic (if not naive) approach and surprise, surprise, i...

Dear All, we have released version 0.6 of the igraph package today. This is a major new version, with a lot of new features, and (sadly) it is not completely compatible with code that was written for the previous igraph versions. (See "Major new features" below for details.) I have included below a list of (bigger) changes. Please see the...

I am getting some unexpected results from some functions of igraph and it is possible that I am misinterpreting the vertex numbers. Eg., the max betweenness measure seems to be from a vertex that is not connected to a single other vertex. Below if my code snippet: require(igraph) my.graph <- graph.adjacency(adjmatrix = my.adj.matrix, mode=c("undirected...

Estimados, estoy ?jugando? con unos datos clínicos donde realizo un análisis de redes, utilicé igraph como nerwork, pero finalmente uso igraph (creo que tiene más opciónes). Son algo de 200 nodos y algo más de 2000 relaciones. Puedo graficarlos. Los datos están de la siguiente forma, por ejemplo, individuo, patología, (las dos primeras columnas son la relación), luego un fármaco, el grupo farmaco...

I'm trying to draw an arrow with a curved shaft on the graph as a straight one looks messy on a detailed graph. I've looked in arrows but it doesn't seem to give an option. larrows doesn't look much more promising. I had a look in the archive and couldn't find anything. Any thoughts?

...a function from a base package, but it does not formally import it via the NAMESPACE file. If another package on the search path also defines a function with the same name, then this second function will be called. E.g. if package 'ggplot2' uses 'stats::density()', and package 'igraph' also defines 'density()', and 'igraph' is on the search path, then 'ggplot2' will call 'igraph::density()' instead of 'stats::density()'. I think that for a better solution, either 1) the search path should not be used at all to resolve symbols in packa...

...'importFrom' in the NAMESPACE of a package allows to avoid conflicts between different packages defining objects with identical names. However, I can still see conflicts while loading the package using 'library'. Here is a toy example, with a package 'foo' importing 'as.igraph' from the igraph package, and 'nj' from ape. 'foo' uses the following DESCRIPTION file: ---------------------- Package: foo Version: 0.0-0 Date: 2013/06/04 Title: foo Author: John Doe Maintainer: John Doe <jdoe at nowhere.org> Imports: igraph, ape Description: just a tes...
