Everything to my knowledge regarding R installed correctly.? I saw no warnings until saving THE WORKSPACE. NON-ROOT OUTPUT CURRENTLY YIELDS

Hello, I've been asked to get R (2.4.1) installed on a IBM p570 server. This is a server with power CPUs and is running SLES 10. It currently has 12GB of RAM so I'd like to make sure I have the 64 bit version of R so as to take advantage of the extra memory. Since it's a power CPU server that means I'll have to compile R from source. I've searched the r_users list but most

Dear R-users, I am trying to produce trellis (png, or jpeg) graphs with transparent background, but I cannot manage to make that happen. I tried to play around with themes but to no avail. Any advise on the following example will be greatly appreciated: Thank you Sebastien #### library(lattice) df <- data.frame(a=rep(1:4,4), b=rep(1:4,4), c=rep(1:4,each=4)) settings <- standard.theme()

Dear R-users, I would like to know if there is a function (in base R or the extension packages) that would automatically detect the break points in a vector x for later use in the cut function. The idea is to determine the boundaries of the n intervals (n>=1) delimiting clusters of data points which could be considered "reasonably" close, given a numerical vector x with unknown

Hi R folks, I'd like to announce several new R users groups here in SF, LA, NYC, and Ottawa - as well as their next scheduled event. The goal of these user groups, besides gently explaining 'drop=TRUE' to the uninitiated, is to exchange knowledge, promote best practices, and spur the adoption of R for innovative applications. If I've missed any groups here, please feel to add on

Dear R-users, I have found on the list several posts addressing the issue of getting data for a list of defined files. However, I found nothing about scanning a given folder and retrieving the list of, let's say, .txt files (I probably used the wrong keywords). Could someone tell me which posts or function help I should look at? Thanks in advance Sebastien

Dear R-users, The following code splits a very simple dataframe into a list, each element of the list being one line of the dataframe. You will see that the split function names each element of the list by using uses the content of a and b and merging them with a "." character. Is there a way to customize this character? a<-1:10 b<-21:30 mydata<-data.frame(a,b)

Dear R-users, In the R internals manual, it is said that one can extract the elements of the dot-dot-dot argument using the special symbols ..1 or ..2. It seems to work just fine but I was wondering if there is a way one can extract or modify the content of the dot-dot-dot argument using a level name instead of its position? For instance, assuming that list(...) returns: $a [1] 1 2 3 4 5

Dear R-users, I have found this not-so-recent post in the archives - http://tolstoy.newcastle.edu.au/R/devel/00a/0291.html - while I was looking for a particular way to reorder factor levels. The question addressed by the author was to know if the read.table function could be modified to order the levels of newly created factors "according to the order that they appear in the data

Dear R-users, I am trying to port to R something that I wrote in Matlab to perform model parameter optimization using the Nelder-Mead simplex method (fminsearch). I read the help on ?optim (which seems to be the way to go) as well as a bunch of posts on the topic, but I would like to make sure about something before I spend to much time trying to reproduce something that is not possible. The

Dear R_Users, I am confronted to a technical issue that I wouldn't even know how to start to handle and where to look at. It is about data manipulation in a dataframe and value substitution Imagine I have a matrix describing a set of chemical equations. Colnames are Components names and Rownames are Reaction names Each cell in that matrix corresponds to the stoechiometric coefficient to the

Dear all, Here is a simplified version of a function I made: ############ plotfunc<-function(x){ #x a vector cat("please select two points","\n") plot(x) points<-locator(2) return(points) } ############ Using R version 1.01 for mac os x (aqua GUI) I would like to know what should I do to make sure that my text line will be printed prior to the drawing of the plot.

Dear R-users, The strsplit function does not exist in S-plus and I would like to use it. How could I reproduce the function in Splus or access to its source code? Thank you in advance, Sebastien

Hello everyone, Very quick question: How should I cite the use of R in a publication ? Thanks in advance. Sebastien

Dear R users, I am currently trying to create my first personnal function and use it with the apply function. The purpose of this function is to create a vector summarizing the number of levels in a given selection of data.frame columns. I tried to transpose the indexation method used by the nlevels function but it doesn't seem to work. I did not find anything uesful in the archives so

Dear R-users, I have written a short VB application to clean and format my R code. Everything works fine except one small issue that I did not expected; it is related the automatic replacement of assignment signs from "=" to "<-". Most functions or arguments seem to accept either = or <-, but some don't (e.g. ls(all=TRUE)). The result is that my supposedly clean

Dear R Users, I am quite surprised to see that mtext gives different results when it is used with 'pairs' and with "plot'. In the two following codes, it seems that the 'at' argument in mtext doesn't consider the same unit system. I would appreciate your comments on this issue. Sebastien ##### Pairs mydata<-data.frame(x=1:10,y=1:10) par(cex.main=1,

Dear R-users, Is there a way I can ask R to execute the "write("hello world",file="hello.txt")" command directly from the UNIX shell, instead of having to save this command to a .R file and execute this file with R CMD BATCH? Thank you Sebastien
