Good afternoon all - While making a steady progress in learning R after Matlab I encountered a problem which seems to require some extra help to move over. Basically I want to merge a data from biological statistical dataset with annotation data extracted from another dataset using an 'id' crossreference and write it to report file. The first part goes absolutely fine, I have merged both

Dear R developers, I have a new class, which I called "Molecule", and have tried to define = a "+" operation for 2 objects of this class. This is what I have written so far, although the method is not complete = (I'm trying to look at it at intermediate stages): setMethod( f=3D"+", signature(x=3D"Molecule",y=3D"Molecule"),

Dear all, I have a very small script to plot a function. Here it is: ########################################## sinca <- function(N,th) { return(sin((N+0.5)*th)/sin(0.5*th)) } plot_sinca <- function(N) { x <- seq(-5*pi,5*pi,by=pi/100) y <- rep(0,length=length(x)) for (i in 1:length(x))y[i] <- sinca(N,x[i]) plot(x,y,type="l",ylim=c(0,2*N+4)) return(c(x,y)) }

Dear R community, I would be greatful if somebody could shed light on the following. I have created a set of 6 points to check how centroid agglomeration works in cluster analysis: > Y <- data.frame(x=c(-1,1,1,-1,10,12),y=c(1,1,-1,-1,0,0)) It is quite intuitive to understand that the last clusters to be joined will be {1,2,3,4} with {5,6}. Now, the centroid for the first cluster has

Dear R gurus and users, I seem to have problem finding the right tool for plotting convex hulls over 2D plots, after a cluster analysis. In fact I would like to draw a convex hull in 2D for a generic group of points. I found a "convhulln", but this doesn't seem to give me a convex hull. Here is what I do: > library(mvtnorm) > Mean <- c(2,1) > Sigma <-

Greetings-- Packages for Lustre 1.0.2 are now available in the usual place http://www.clusterfs.com/download.html This bug-fix release resolves a number of issues, of which a few are user-visible: - the default debug level is now a more reasonable production value - zero-copy TCP is now enabled by default, if your hardware supports it - you should encounter fewer allocation failures

Dear RGL experts, I haven't been able to add greek letters to my rgl plot3d. I have tried "expression" with no success. Here is the interested bit: > library(rgl) > cb <- cube3d() > plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5) The expression(alpha) appears as "alpha", rather than as a greek symbol. I suspect greek

Dear R community (and Duncan more specifically), I can't work out how to make additional light sources work in rgl. Here is the example. First I create a cube and visualize it: > cubo <- cube3d(col="black") > shade3d(cubo) Next I position the viewpoint at theta=0 and phi=30: > view3d(theta=0,phi=30) Next, I want to create a 2nd light source which diffuses red light

Dear R community, I would like to source a file in my linux system to set a few environment variables. I have tried: > system("source /home/james/build//ccp4-6.1.13/include/ccp4.setup") and got: sh: source: not found In fact, using Sys.which("source") I get an empty string. How can I source that ccp4.setup file from within an R session? J Dr James Foadi PhD Membrane

Hi, I am currently working on fitting a mixture density to financial data. I have the following data: http://s000.tinyupload.com/?file_id=00083355432555420222 I want to fit a mixture density of two normal distributions. I have the formula: f(l)=πϕ(l;μ1,σ21)+(1−π)ϕ(l;μ2,σ22) my R code is: normalmix<-normalmixEM(dat,k=2,fast=TRUE) pi<-normalmix$lambda[1] mu1<-normalmix$mu[1]

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings! I tried installing CentOS v7 (1406) to an old spare machine, and the video card apparently don't play well with X. It is incorrectly saying that either monitor I connect is only able to support 640x480, when one is 1024x768 and the other supports a higher (but now forgotten) resolution. In no way do I expect a fix to be added just to

Hi, I am very confused with constructing the wilcox.test in R. I have two populations 'original' and 'test'. I want to know if the 'test' is generally 'lower' than original. I use alpha of 0.05. So do I write the function as wilcox.test(original, test, alternative="l")? or wlcox.test(original, test, alternative = "g")? or wilcox.test(test,
