Hello world, I have a very strange update problem: this night I upgraded from 3.0.5 to 3.0.6 (debian unstable) and the system broke completely with very strange errors (I did not change anything to smb.conf) - win98 users can log in, copy and everything - xp users can log in, they see the shares but they cannot access the files (read error in xp). I have tested it with Xp-Prof SP1 und SP2

If _you_ were asked to give a 40 minute dog and pony show about R for a group of scientists ranging from physicists to geographers what would you put in? These people want to know what R can do. I'm thinking about something like: A. Overview B. data structures C. arithmetic and manipulation D. reading data E. linear models using glm F. graphics G. programming H. other tricks like rpart or

Hello world, I am actually transferring a course in data management for students in biology, geography and agriculture from statistica to R - it works surprisingly well. If anyone is interested in my scratch/notepad (in German language), please see www.hydrology.uni-kiel.de/~schorsch/statistik/statistik_datenauswertung.pdf (pages 40-52) The dataset is:

Hello world, I am actually trying to transfer a lecture from Statistica to R and I ran into problems with spectral analysis, I think I just don't get it 8-( (The posting from "FFT, frequs, magnitudes, phases" from 2005 did not enlighten me) As a starter for the students I have a 10year data set of air temperature with daily values and I try to get a periodogram where the annual

Dear all R-helper, if I want to use stdout from other language as my R program input ,which is the best way for design the API,using Pipe function or produce a temporary file,using scan function to read the file ? thanks Michael

Hello... I would like to use R for 'pipelining' data among several programs. I'm wondering how I can use R to call another program, feed that program a set of parameters, and retrieve the output. E.g., I have an executable that, when opened, prompts the user to enter a set of parameters. The program then executes & prompts the user for the name of an output file. I need to

Hi, I am trying to figure a way to allocate a string SEXP so that gc() won't ever collect it. Here is a little bit of a background. Suppose I want to write a .Call-callable function that upon each call returns the same value, say mkChar("foo"): SEXP getFoo() { return mkChar("foo"); } The above implementation doesn't take advantage of the fact that

The release schedule has now been set with a release date on April 18. The detailed procedure can be found at http://developer.r-project.org/ (it is not quite there yet, but will appear after a short propagation delay.) The main point for non-developers is that we start making alpha tarballs on March 21 and beta tarballs on April 4. Only very simple and/or critical bugs are fixed in the last

I have used Sweave a lot the latest year, but never really used any long function calls. If I have code which look like this ------------------------------------------------------------- gof <- benthic.flux(ID="Gulf of Finland", meas.conc=conc, bw.conc=bw.conc, time=times,

Hi, for presentation purposes I would like to clear to whole console window (like in a UNIX terminal: 'clear'). Is there such a function? If not, I could image that is not too hard to write such a function. Cheers, Hans

Can anyone point out why this is not working? y<-read.table(pipe(' awk '{ n = $1; sub( ".*" $1 " " ,"") ; while ( n-- ) print }' temp.txt ')) [[alternative HTML version deleted]]

Hello, This code works fine but is so fast I can't see anything but the last plot. for (i in nrow(X)){ plot(as.numeric(d[i,])) } I'd like to view a plot every 500 milliseconds, nrow(X) = 400. How?

Dear all, I would like to start a process from an R program in such a way that I can both feed input into the process and read the process's output. It seems that in R, I can have a pipe for writing into another process's input or a pipe for reading from another process's output, but not both. Doing both necessitates forking, such that the child can start the external process and

How precise is R numerically? For example I wrote the following function for calculating the volume of the ball inscribed in the unit cube in m dimensions. In order to see what happens in 40 dimensions, I created an output of 24 digits. But how many are precise? Thanks Josef Eschgf?ller Ferrara --------------------------------------- Vol = function (m) {if (m<=1) 1 else Vol(m-2)*pi/(m+m)}

I have been using the fork package on a cluster to spawn jobs. I have noticed that I end up with many "R defunct" (zombie) processes following the use of fork that do not die completely until I close down R. Initially, I thought it may be my code but I ran the example from the latest fork package (see code below) on R.2.3.1 and ended up with the same problem. The code from the

Hi, I am using the following command to print to a file (I omitted the file details): cat( paste( paste(orientation, start, end, names,"\n"), paste(start, end, "exon\n"), sep="")) where "orientation" and "names" are character vectors and "start" and "end" are integer vectors. The problem is that R coerce the integer vectors

Can anyone please help me understand whats happening here?

Hi Dumb question time again, for which I apologise. I have a variable that contains the following numerical text "04010". This is the name to access a list: > as.list(KEGGPATHID2NAME)$"04010" [1] "MAPK signaling pathway" Marvellous! Except I want to do that when "04010" is assigned to a variable called path and I can't figure out how to do it!

Dear all, Thanks to those 3 people who sent me answers to my question. Got the problem solved. Great! Now, another question of mine is: I would like to run an R script from the Linux prompt. Is there any way possible to do this? The reason is, the calculation that I'm doing takes a few hours, and I would like to automatize it. Or does it mean that I have to run source within the R
