I have a network loaded into an igraph object G that has 198 vertices and 214 edges. If I run: eig<-evcent(G)$vector The resulting eig is a vector with 2172 elements, rather than 198 elements. The documentation on the package claims it returns the "centralities of positions v." Any ideas on how to get the eigenvalue centralities f...
I have the following vector: tmp3 <- c("1500 2", "1500 1", "1510 2", "1510 1", "1520 2", "1520 1", "1530 2", "1530 1", "1540 2", "1540 1") I would like to just retain the second number in each of the atoms of this vector so it would read: c(2, 1,2,1,2,1,2,1,2,1). ...
I am trying to find out whether the R programming language is interpreted or compiled. Can't seem to find this info. Edit I should have said interpreted or compiled to begin with. Commenters are absolutely right - static or dynamic has nothing to do with whether the language is interpreted or dynamic. ...
Hello, I was seeing that here we have a new language(for me it is), R, but I was viewing it's site and as I can see we only can do graphics with it, but there is more things that we can do with it? ...

I have written a very basic package in R. In fact, I followed this tutorial for creating a basic package. My package works just fine in linux. eg: > install.packages("linmod", repos=NULL) Warning in install.packages("linmod", repos = NULL) : argument 'lib' is missing: using '/home/jpgoel/R/i486-pc-linux-gnu-library/2.9' * Installing...

I'm plotting a group of curves, using facet in ggplot2. I'd like to have a smoother applied to plots where there are enough points to smooth, but not on plots with very few points. In particular I'd like to stop the plot failing when one of the panels only has 1 or 2 points. Example: a <- data.frame( x=1:100, y=sin(seq(0.1,10,0.1) )) ...

This question came today in the manipulatr mailing list. http://groups.google.com/group/manipulatr/browse_thread/thread/fbab76945f7cba3f I am rephrasing. Given a distance matrix (calculated with dist) apply a function to the rows of the distance matrix. Code: library(plyr) N <- 100 a <- data.frame(b=1:N,c=runif(N)) d <- dist(a,diag...
I may be Doing It Wrong™ but I have a dataframe and for each row in that dataframe I have to do some complicated lookups and append some data to a file. In my procedural world, I'd do something like: for (row in dataFrame) { #look up stuff using data from the row #write stuff to the file } what is the R way to do this? Updat...
Is there an open source and/or free statistics package or library for Delphi? I'm looking for something that can compile directly into the executable, so no DLL's. It needs to be compatible with Delphi 2009 and later (the Unicode versions). Hopefully there is something comprehensive available out there. By comparison, I am used to the a...
How do you debug a generic function (using debug, or mtrace in the debug package)? As an example, I want to debug cenreg in the NADA package, specifically the method that takes a formula input. You can retrieve the method details like this: library(NADA) getMethod("cenreg", c("formula", "missing", "missing")) function (obs, censored,...
I have been working on a few R packages for some general tools that aren't currently available in R: blogging, report delivery, logging, and scheduling. This led me to wonder: what are the most important things that people wish existed in R that currently aren't available? My hope is that we can use this to pinpoint some gaps, and po...
Sorry for the non-descriptive title but I don't know whether there's a word for what I'm trying to achieve. Let's assume that I have a list of names of different classes like c( '1', '2', '3', '4') I'd like to generate all possible permutation pairs out of this so that there are no reverse-duplicates. So what I'd like to have is some...
