Hi to all, does anybody knows whether there is a package to plot those http://www.equine-science.de/temp/graph.jpg graphs. the thickness of the points and/or the lines should be represent the numbers of behaviours With kind regards Knut

Hello R Help Team, I have created graph from weighted adjecency matrix .Is there a way I can find highly connected nodes in Igraph like the Package RBGL does. nathan -- View this message in context: http://www.nabble.com/Highly-Connected-Nodes-in-Igraph-tp22377522p22377522.html Sent from the R help mailing list archive at Nabble.com.

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

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

Hi, I have a data set consisting of the x and y coordinate locations of 1600 points. I would like to generate a graph using the functions in igraph. However the graph making functions in igraph requires the data to be in the form of an adjacency matrix. I'd like some advice on how to convert my point pattern to an adjacency matrix or functions out there that would do it directly. I've

Hello All, I have been trying to do bonpow for a while now.Bonpow works for few graphs and for few others it goes out of memory. I did see reply to one of the posting Alph Centrality Crashed in Igraph memory error. The solution in the posting was to use sparse matrix. This is the link of the message. http://lists.gnu.org/archive/html/igraph-help/2008-04/msg00071.html I was able to obtain

Dear R users, I am trying to draw a network using igraph package. I intend to place the hub nodes (the ones with the relatively more connection with other nodes) in the center of the graph. Also, the graph need to be in the fashion that the higher the correlation between two nodes is , the closer the two nodes will be. Is there any layout that can help or any other way to do this? Thanks in

Hi R users, I am using built-in functions in igraph package to draw networks . I need to compare several network with exactly the same structure but with edge hightlighted differently. I am wondering if there is a way to save the layout so that every graph will look the same as each other except for the colors of edges. Or is there any parameter I can set for this purpose?? Thanks in advance,

I have a number of (directed) graphs based on social groups, where the members have expresed likes and dislikes in respect to the other members. tkgraph makes it simple to draw the graphs in a very pleasing way, but I would like to differentiate between positive and negative relations in the graph by having the edges for the negative relations dashed and the positive ones continuous. Is

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 <-

When the shape of all vertices is set to "square" and the size of the vertices is also set, one get following error (commands attached): Error in l[[which.min(sapply(l, function(p) (p[1] - x0)^2 + (p[2] - y0)^2))]] : attempt to select less than one element Is there a way to solve this problem?

Is there any function to show the points like this example of SPSS? http://biostatistic.de/temp/reg.jpg The point size should represent the number of data at this point. with regards Knut Krueger

R 2.4.0 for Windows The following plot appears as a squared window (as all r-plots) Not all subtitles are visible, but all subtitle will appear, when changing the aspect ratio of the plot window with the mouse to a wide format. But does not work when using the save as postscript menu item from the plot window. is there any solution for that? opar <- par(mfrow = c(2,2), oma = c(0, 0, 1.1,

Is there any possibility to get high resolution plots in a windows xp system? I tried it with the device function png(filename = "c:/r/highresplot%d.png",pointsize=12, res=900) but when I try to set: width = 480, height = 480 or pointsize = 12, the text is not scaled in the same way as the plots. with regards Knut Krueger http://www.biostatistic.de

Hi to all I need a string like temp <- paste("m1","m2","m3",sep=",") But i must know how many items are in the string,afterwards the other option would be to use a vector temp <- c("m1","m2","m3") No problem to get the count of items but I must get afterwards the string "m1,m2,m3" No problem to build the

Hi to all, test <- data.frame("X"=c(1:4),"Y"=c(5:8),"Z"=c(8:11)) test <- test[,-2] Is there a way to specify the col name "Y" to delete instead the number? Kind regards Knut

Dear R list, For some reason I am unable to access neither search.r-project.org, nor http://finzi.psych.upenn.edu/ so I cannot search the archives for a possible answer (I Googled for this but didn't find anything). Is it possible to draw barplots using a texture instead of colors, for a black and white printer? TIA, Adrian -- Adrian Dusa Arhiva Romana de Date Sociale Bd. Schitu

If there is a helpfile open (f.e ?glm) and it is the top window, then an exception error occurs (closing RGUI) when I hit the open file button. If the helpfile is not the top window (of the RGUI) I am able to open a new script without any error. The RGUI is not closing complete there is a blank screen left which I have to close with the X Button or Taskmanager Windows XP Home - German Version

Hi to all, I am just looking for more efficient ways ;-) is there a better way instead a loop to decrease x if greater y test <- c(1,3,5,7,9) decrease if greater 1 to test2 <- c(1,2,4,6,8) Kind regards Knut
