Dear all, It is my understanding that using 'importFrom' in the NAMESPACE of a package allows to avoid conflicts between different packages defining objects with identical names. However, I can still see conflicts while loading the package using 'library'. Here is a toy example, with a package 'foo' importing 'as.igraph' from the igraph package, and 'nj'

In their paper, "Lexical Scope and Statistical Computing", the authors ( Gentleman and Ihaka ) go to great length explaining why R's use of lexical scoping creates advantages when doing statistical computations. If anyone has or is familiar with this paper, could they provide the main program code for how the "newton" function would be called in their example on page 500

I'm an Rgraphviz newbie trying to figure out how to do some things/whether they are possible. Apparently graphviz does allow you to modify line widths of edges: see https://mailman.research.att.com/pipermail/graphviz-interest/2001q2/000051.html (although it looks a little obscure even in graphviz). [As discussed in the thread above, the "weight" parameter in Rgraphviz sets the

hello! my question conserns with use of "panel" package (written by R.C.Gentlman) (unfortunately the manual and help sites are very short) 1. is it possible to do analysis just without a(ny) covariate? i suggest do it by introducing a covariate with level=0 in all obervations, this because of Q(z)=Q_o exp(beta*z), but it seemingly doesn't work 2. in the option gamma in the

Dear R Users, I am looking clique a graph technique, to identify the values from the dataset. I tried with help.search("graph") it show's the graphics related stuff Is there any package that i can use to find Clique in a dataset? Thanks in Advance JJ -- Lecturer J.

Hi all. How do I extract date from fcs format file with R. I.e I'd like make statistical analysis using R-program, but I don't know if there are R-packets for fcs format file, and using examples. Thanks. Pta: In Linux SO exist any program that transform from fcs format to ASCII text file?

Hello, Does anyone know of a way of finding all the nodes that are between a pair of specified nodes in the excellent graph package (R vers 2.5.0). I have a class(graphAM) object and need to determine all possible pathways in this object. Here's an example: In the simple case of a--b--c (where -- denotes "conected to") the list of all pathways would be: ab ba abc cba cb bc.

Hi All, does anyone know how to import binary .bed files generated by Plink (http://pngu.mgh.harvard.edu/~purcell/plink/ ) into R? the Plink FAQ explains how to conver other types of files, not the .bed.

I am aware of the R Genetics Project that developed the R library and software called Bioconductor (http://www.bioconductor.org/ ) . How do the two relate to each other?

A colleague sent me the following: If you specify probabilities in the 'sample' function and forget to type 'prob=...', then you get nonsense. E.g. sample(1:10,1,c(0,0,0,0,1,0,0,0,0,0)) does not filter '5', while sample(1:10,1,prob=c(0,0,0,0,1,0,0,0,0,0)) does it correctly. I wish this would return an error because the

Hello there, I am using the igraph package to build graphs from my data. If I plot a graph though, it's not easy for me to see what's going on. Does anybody know how to rearrange a graph to get a plot without too many crossing lines? Maybe other packages?
