similar to: e1071 question: what's the definition of performance in t une.* functions?

Hi, all. Something strange happened to my ESS. I use Mac OS X. When R is used in stand alone mode, it recognizes external libraries like "affy", "e1071" etc. However, when R is invoked through ESS in Emacs, it produces errors like: Error in library(affy) : There is no package called 'affy' Interestingly, I remember I successfully used these libraries through ESS in

Hi, all; Our group is planning to develop a web-based analysis package with R. I have some questions. (1) Can we use R as a daemon-like way such that, after invoking R and making it run in a kind of background mode, just put some R script into R using some pipe-like mechanism and retrieve the result out of it? (2) If this is possible, then how can we do it? If this is not possible, then what

Hello. By way of background, I am running out of memory when attempting to normalize the data from 160 affymetrix microarrays using justRMA (from the affy package). This is despite making 6 gigabytes of swap space available on our sgi irix machine (which has 2 gigabytes of ram). I have seen in various discussions statements such as "you will need at least 6 gigabytes of memory to normalize

Hi, all; I got an unusual error while using mclust library 2.1-7 on R 2.0.1. When I tried to run Mclust(rnorm(100)), I got segmentation fault error. Does anyone know what causes this problem? I came across the same problem even when I tried to run the example shown in Mclust help using iris data.

Hi, All; I have a question. In R, what is the best way to make R idle for a while and try something again later? For example, suppose there is an R job which accesses a file that may be shared with other active jobs. So when the file is being accessed by other job, your job will not be able to access the file and your job will crash because of that. To avoid this, you want your job to try to

Hi, All; When I generate a "special" paper postscript image larger than "a4" or "letter" using R, I can only see one-page portion of all image, of course. What will be the simple solution for this? Is there any way I can set the bounding box information on the image? Or any other suggestions? Thanks in advance; Tae-Hoon Chung

Hi, All; Suppose I have a class 'dat' such that setClass('dat', representation (.version='character', x='numeric', y='numeric')). If I want to make a method that changes the .version slot of 'dat' class in a way like set.version(d) <- '0.2' when d is an object of 'dat' class, how can I do this? Thanks in advance. Tae-Hoon

Is there any requirement for TclTk support for R? When I tried to call the tcltk library, it failed with the following message: > library(tcltk) Error in firstlib(which.lib.loc, package) : Tcl/Tk support is not available on this system Error in library(tcltk) : .First.lib failed for 'tcltk' The system information is as follows: Linux osirus.tgen.org 2.6.9-42.0.10.ELsmp #1

I'm trying to select a subset of a dataframe while dropping some factors. While the dataset gets smaller all Factor levels remain and I need to get rid of them. Strangely enough, I am almost certain that the same code on the same data worked OK earlier today - and it is not the first time that I'm not able to replicate earlier results with this command (I know, I might just be going

Hi, All; I tried to use library mclust in 64-bit compiled R 2.0.1 but failed. Installation went smoothly without any warning or error. However, when I tried to use them with the following simple code, it crashed. Library(mclust) Dat <- c(rnorm(20, mean=0, sd=0.2), rnorm(30, mean=1, sd=0.2)) Ind <- Mclust(dat, 1, 5)$classification cbind(Dat, Ind) The error message was:

Happy new year to all; A few days ago, I posted similar problem. At that time, I found out that our R program had been 32-bit compiled, not 64-bit compiled. So the R program has been re-installed in 64-bit and run the same job, reading in 150 Affymetrix U133A v2 CEL files and perform dChip processing. However, the memory problem happened again. Since the amount of physical memory is 64GB, I think

Hi, all; I know there has been a lot of discussions on memory usage in R. However, I have some odd situation here. Basically, I have a rare opportunity to run R in a system with 64GB memory without any limit on memory usage for any person or process. However, I encountered the memory problem error message like this: Error: cannot allocate vector of size 594075 Kb I got this error message while

Hi, Is there any possible way to connect to VB, VC++, Delphi, Python, etc... to R? I am trying to put some nice GUI using something like VB and use R as a back end for computations. I search through the FAQ and help archive, but could not find any. I am willing to look at any tools on Sun/Solaris environment as well (Like C or Python or Perl). If anyone can share some examples, pls let me

Greetings, I am a bit confused by the results returned by the functions: cohen.kappa {concord} classAgreement {e1071} when using a two-way table. for example, if I have an matrix A, and a similar matrix B (same dimensions), then: matrix A and B can be found: http://casoilresource.lawr.ucdavis.edu/drupal/files/a_40.txt http://casoilresource.lawr.ucdavis.edu/drupal/files/b_40.txt A <-

I was wondering, whether there is a way to have statistical significance test for cluster agreement. I know that I can use classAgreement() function to get Rand index, which will give me some indication whether the clusters agree or not, but it would be interesting to have a formal test. Thanks.

Hi, First time on this list. Here it goes I am trying to find Loess. I could not find it on the windows version. Is there one in either Unix version of R or some C program somewhere? I tried one from http://netlib.bell-labs.com/netlib/a/, but I cannot get it to compile due to problem with missing lib (I think): cc -o gas.x gas.o loessc.o loess.o predict.o misc.o loessf.o -llinpack -lcor -lm

Hello: I modified benchmark used in http://www.informatik.uni-frankfurt.de/~stst/benchspl.txt now the attached code will work with R, except for last test for some reason (Sorry ran out of time to play with this). Immediate problem is that R does not show fraction of seconds. So, that kinda makes comparison some what hard. I also looked at memory and CPU usage on NT console. R seems to go
