hi I am struck with a problem in igraph package of R. My problem is as follows I want to plot a power law fit for my data (in .net format --- pajek format) syntax for that in R is g <- read.graph("filename.net", "pajek") d <- degree (g, mode="in") power.law.fit (d+1, 2) it gives me desired out put if my if input a single file but I want to use a variable

Hi I am using igraph package in R. My goal is to read a network (in "pajek" format) and decompose the network into components. In addition, I am also interested in sending this output to to a file. I am having problem in while writing to a file! my code looks like this g <- read.graph ("F://test.net", "pajek") compo <- decompose.graph(g,

Hi, Does anyone know of a package in R that has a function to convert network data (e.g. an adjacency matrix or ) from 2-mode to 1-mode? I am conducting social network analysis. I know that Pajek has this function under Net --> Transform --> 2-mode to 1-mode --> Rows. I have searched the documentation under packages 'sna', 'network', 'igraph', and

Hi friends, Is there anyone who happened to import data set in the "DL" format into R for further analysis? In the package of "network", there's only a method named "read.paj()". So now, I have to get the dl file from the original data set, and use UCINET to convert it to .net file. It's too complicated. :( In the package of "igraph", edgelist is

Hi everybody!I'm a new user of R. I've been having a look to sotored mails in list, but I've been not able to find one suiting to my need. The issue is I have a neighbour list in a TXT file, just as lists generated by social network softwares (f.i. Pajek), where you get Field1, Field2, Value. In my case, list follow the next way:ID1 IDP2 SUMVAL1 56 0.0659358951 900 0.0441101851 1409

Hello: I've been trying for days now to get igraph working on a debian sarge install. There does not appear to be any pre-built packages, and when I try and install within R, it blows up on the final linking, claiming its unable to find libgfortran (which IS installed, and IS working for all other users of the compiler). I started up R and ran: install.packages("igraph"). It

Hello! I was just wondering, why only one of my "Rd" files is converted in "chm" format (REGE) and the other are not when installing a package? The output from installing a package on WinXp is below. I tried to find more information about what "chm" format actually is, however have found none. Best regards and thaks for any replies, Ales Ziberna

Hi All: This follows my earlier post on webized slides on lecture presentation on introducing R. I learned that in Mozilla (Firefox) browsers, the slides did not show up. Sorry for the no show. As a reluctant windows user, I kind of carelessly clicked through Powerpoint to convert the presentation file to its html form, unwittingly leading to the mess. See if it got corrected now (I do not have

I didn't go into details when I asked the question for feat that I would overly specific and blur my real goals. The links between variables are defined as conditional probability distributions. So if the probability distribution of a variable X's value is conditioned on the probability distribution of the values of Y and Z, we say Y and Z are X's parents, and in the network,

Here are another three problems with logarithmic scales: 1) segments() does not work with logarithmic scales. I suggest to change lines 962-973 in "plot.c": for (i = 0; i < n; i++) { if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0])) && FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) { GP->col = INTEGER(col)[i % ncol];

I''m looking for someone to do a quick freelance programming in R to do some network analysis. I''m a researcher with no knowledge in R (doing all my statistics analysis in Stata and network analysis in UCINET). I would like to quickly test the possibility to do batch network analyses using R. The freelance should therefore write a small program that would take as input a file

The (*windows only*) xlsReadWrite package has been updated and the new version is available on CRAN. xlsReadWrite natively reads and writes Excel files (v97 - 2003). o Changes from v1.1.1 to v1.3.3 (versions between never really published) - ROWNAMES-support also for matrices (not only for data.frame) - explicit rowNames argument in interface.

Hi, I wrote a program in PERL which creates a file with .net extension (.. xyz.net). I want to call R from within my PERL program, execute 3-line command in 'R', store the output and get back to PERL program. RSPerl is of omegahat is a good software which creates interface between R and PERL, but unfortunately it doesn't work on my Windows XP. I used the following command in PERL to

igraph is a package for graphs and networks. It has a C core and uses a simple and fast graph representation allowing millions of vertices and edges. NEW FEATURES: - We use the ARPACK library for graph related eigenvalue problems, like Page Rank calculation, Kleinberg's hub and authority scores, eigenvector centrality, etc. There is also a generic interface if someone wants to use

Hey, all. I'm looking for packages that are good at two things 1) Drawing directed graphs (i.e nodes and edges), both with single and double headed arrows, as well as allowing for differences in line width and solid versus dashed. Note: I've tried Rgraphviz here, but have run into some problems (which seem fixable and I may go with it in the end), and it doesn't satisfy need

I found it useful to have contour be able to do line widths ... hope that the guts haven't changed an enormous amount in the current development version ... the patches are relatively trivial, mostly going by analogy with lty and col (although in my ignorance it took me a while to figure out what UNPROTECT(2) was and why it should be changed to UNPROTECT(3) ... hope this is useful.

G'day, I am new user to R, and have been thrown in the deep end with a something my company want me to write. my code is as follows: kenttemp=read.csv("mnowak.11.1.csv") rows=nrow(kenttemp)-5 kent=kenttemp[1:rows,] #have to remove the last 5 lines of the graph as they interfere with rest of data max(kent[,16],na.rm=TRUE)->ymax ymax=ymax+200 #This is to get
