hi,
You should probably be looking at the functions in the following packages: sna network(s) graph dynamicgraph mathgraph igraph Matrix and a few others ;) what you're describing sounds like, to my ear, a restricted social network diagram; many of the problems you describe are typical of such problems, and are accounted for in the packages described above. The most difficult part is likely to be the plots; handling an annotated, weighted, complex network is fairly straightforward in terms of data handling and analytic tools (e.g. regressions on networks are common...). --elijah On Tue, 13 Nov 2007, Manal Helal wrote: > Date: Tue, 13 Nov 2007 12:44:16 +1100 > From: Manal Helal <[EMAIL PROTECTED]> > To: r-help@r-project.org > Subject: [R] connection diagram > > Hi > > I am practically new to R, and need to construct connection diagrams, > I have a table of data, of nodes in vertical rows, and horizontally > the number of outgoing connections to other nodes, and the indices of > these nodes, each in a column, so some columns are used, and some are > not, based on how many connections I have > > the node is identified by these variables (dimension, wave number, > partition number, index) > > the number of incoming and outgoing connections to each nodes varies, > but obviously there is a relationship > > First: I need to draw diagrams of these connections > Second: I need to apply regression analysis on this data, to predict a > closed formula of how the 4 variables above decide how many incoming > connections, and outgoing connections, and from/to which node(s) > > Am I making sense? if so, is this doable in R? or do I need to use > other tools?
