Hi All, I am making a serious effort to try to learn R, but one hurdle I am facing is that I need to "see" the data as I walk through the examples in the packages. For instance, many examples on the web start by a command like data("wines"). How can I actually view what the dataset looks like prior to transformations and analysis? I have tried to use edit() , print, and

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

Can you please show code example, how to draw graph with some nodes and edges, but with weights. I only found here http://www.bioconductor.org/packages/release/bioc/vignettes/Rgraphviz/inst/doc/Rgraphviz.pdf- Using edge weights for labels, but... Here an example: > library("graph"); library(Rgraphviz) > myNodes = c("s", "p", "q", "r") >

Hi All, I am new to R, but it has been a lot of fun learning as I go and have been blow away by what it can do. Came across this example and wanted to see if ggplot2 or some other visualization package could make this sort of graphic.

Hi all, I am new to R, but with the help I have received thus,I have already been able to work through a bunch of questions on my own in just a few days. I imagine my questions are relatively simple, but here she goes. 1) I am using a package where one of the objects generated represents X/Y coordinates for each observation. I have been able to plot my row names onto the graph using text()

Hi Everyone, I was hoping someone could help me with the settings for Tinn-R. I see in the screen shots that it has syntax help, or something similar (tips on what functions, etc). I can not seem to get this to turn on in the program, and I am wondering if I have to set up a few options. I quickly read through the help and could not figure it out. Many thanks! - Brock P.S. It appears as

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

Hello everone, I am a computer science researcher in the UK - and have a quick question regarding importing data into R and more specifically latentnet. I am trying to import data such as a text file containing: (This is based on the Sampson data set) ----------- Network attributes: vertices = 3 directed = TRUE hyper = FALSE loops = FALSE multiple = FALSE total edges=

Dear all, I have a undirected network (g), representing all the sexual relationships that ever existed in a model community. I also have a directed edgelist (e) which is a subset of the edgelist of g. e represents the transmission pathway of HIV. Now I would like to superimpose the picture of the sexual relationships with arrows in a different colour, to indicate where in the network HIV was

Hi Everyone, I am relatively new to R, but I want to try to learn how to use it and potentially replace the other commercial packages I have learned to use over the years. That said, I need to get at data in databases, more specifically, MySQL. I installed the RMySQL package without error, but when I try to load it, I get the following error: > library(RMySQL) Loading required package: DBI

Hi all, Can anyone help me setup this package so I can use it. I am getting errors with the Rgraphviz package and have tried a number of ways to get this to work. Any help will be greatly appreciated! I am sorta new to R but have been actively trying to get into using it as my main analysis software. Thanks, Brock [[alternative HTML version deleted]]

Hi All, I am still learning R, but making, IMO, great strides. I learned about Kohonen/Self-Organizing Maps in class and I would like to try to replicate some of the things we have seen in class. Below is my code. I am trying to create a u-matrix. In the documentation on page 9 it appears the type of plot, dist.neighbours should do the trick, however, I am getting an error: (Error in

Hi, I am using 7-zip for unzipping (http://www.7-zip.org/). Then odfWeaveControl needs to be set to odfWeaveControl(zipCmd=c("c:/programme/7-zip/7z a -tzip $$file$$","c:/programme/7-zip/7z x $$file$$ -aoa")) -> control where 'c:/programme/7-zip/' is the path to my 7-zip installation. You can then use control to set the control-parameter in odfWeave. Frank

Hi, I am an R newbie. I am running R2.5.1 on WinXP. I am trying to run a pacakge (BNArray1.0) that depends on deal 1.2-26 and dynamicGraph 0.2.0.1 . These are available on http://www.cls.zju.edu.cn/binfo/BNArray/#OLE9 . I have installed the 3 packages (using local files). When I try to run BNArray, I reveicd this error message > local({pkg <- select.list(sort(.packages(all.available =

Hi All, This is probably basic, but I am just starting with R and very interested in learning how to automate my reports. I am just learning about Sweave and LaTex. I am following an example from online and am getting the following error: ....."Error unizipping file....unzip not found". I am not a programmer by any stretch, but I realize that the package is either not recognizing

Hi everyone, I have successfully created and analyzed my network data. I am new to R, and Network Analysis too, but I want to color my vertex based on some of the centrality measures calculated. Can someone point me in the right direction? Again, I am new to R, but given how powerful R appears to be, I figure this is probably pretty easy to do, I just wish I could figure it out. Many thanks

Hi everyone, This is my first posting and I am just starting to fumble my way thru R. I have been working thru the Arules package, and I used to be able to use the image function and I get the following message: Error in image.default(basket2) : 'z' must be a matrix I used to be able to plot the image. I only started to get this error when I tried to add x and y axis labels.

1 down vote favorite my problem is the following: I am using the R SNA package for social network analysis. Lets say, my starting point is an edgelist with the following characteristics. Every row contains a firm name, the ID of a project they are involved and further characteristics, let's say the projects year. Firms can be in several projects, and one project can consist of a

Dear R users I'm a novice user of R and have absolutely no prior knowledge of social network analysis, so apologies if my question is trivial. I've spent alot of time trying to solve this on my own but I really can't so hope someone here can help me out. Cheers! The dataset: I'm trying to predict the existance of links (True or False) in a test set using a training set. Both

I'm interested in computing densities of a number of small ego-centred or local networks. I've installed both the R program and the sna package. My next task is importing the data into R. Our data was entered into Spss in an edgelist format in which each case specifies the link between an alter and an ego. For example: 10101 10102 1 10101 10103 3 10102 10104 2 10201 10203
