Envío el mismo código con un head, observar que el data.frame no es al estilo: degree(datos.network) 1 Ficha 1022 9 2 Ficha 1024 10 > version _ platform x86_64-w64-mingw32 arch x86_64 os mingw32 system x86_64,

Si, ese es el problema, lo que implica por ejemplo que no pueda ordenar el data.frame por grados.

Estimado Luisfo Chiroque Hay aristas múltiples, eso es por la preparación de los datos, es que separe por componentes, no me refiero al término componente estadístico, sino a descomposición de algo en los componentes que lo construyen, algunos son comunes y otros no, cuándo son comunes hay una relación en la red. Voy a probar con simplify, cuándo lo leí yo lo descarté, lo releeré, ¿Qué opina de

Hola a todos: Apliqué el método, pero me salió lo siguiente; error in FUN(X[[i]], ...) : only defined on a data frame with all numeric variables. Me imagino que el error surgió ya que la tabla de valores que necesito encontrar tengo "FECHAS", "HORA" Y NUMERO . Por ejemplo; fecha hora datos 20/11/12 2:00:04 AM 12.905 21/11/12 3:00:04 AM 12.889 22/11/12 4:00:03 AM

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)) : unable to load shared library

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. Thanks for your help. > library(igraph) Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object

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.

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.

Estimados compañeros estoy con un trabajo sobre redes pathfinder y quería saber si conocéis alguna librería o función para dada la matriz de proximidades sacar la matriz de la red pathfinder.

Hi! I want to use R for network analysis and have tried to install the 'igraph' package. Unfortunately, the installation is aborted by an error: --snip-- gcc -std=gnu99 -I/usr/lib64/R/include -DNDEBUG -I/usr/local/include -DUSING_R -I. -Ics -Iglpk -Iglpk/amd -Iglpk/colamd -I/usr/local/include -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables

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")) most.between.vert <-

Dear R users: There appears to be a conflict between the statnet package and the igraph package. With igraph loaded into memory, the network() function of statnet failed, returning the error to the effect that the matrix being converted was "not a graph object." Removing igraph from memory restored statnet to proper function. Apologies if this is redundant. I could not find this

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

Dear R users, I'm using graph library to create a mesh-like network topology and implement a load balance routing algorithm. The current implementation uses graph, RBGL, and Rgraphviz libraries. I have a few attributes on every edge to represent the network loading and capacity, and I frequently update these values. However, I found it works so slow and right now I'm consider rewriting it

Hi, So I've been figuring out how to use igraph in R and like it for it's speed and simplicity. Now I have a graph built from an edgelist where vectors have a $name attribute. I have another dataframe with attributes tied to a vector ID, which is the same as the $name attribute of vectors represented in the graph. How can I iterate over the graph by V(g)$name and do

Hi R-users, I'm using igraph for an undirected graph. i used clusters() igraph function to know the component size(subgraphs) as shown bellow: c <-clusters(g)    # component sizes size <- sort(c$csize, decreasing=TRUE) cat("Top 20 cluster of the graph","\n") for (i in 1:20) {   cat(i,"  size:",size[i] ,"\n") } Can anyone help how to extract the
