Dear R-users and expeRts, can anyone provide me (and others as well, of course) with reference of companies, scientific labs and/or schools where R is being used? Or does some (even unofficial) list of comanies etc. where R is being used exist? I tried to find such an information on R's homepage and on a FAQ page, but unsuccesfully. (Of course, searching through this r-help conference one

Hello, in order to vectorize task (of plotting barplots), I use, as probably all R-folks, function apply() instead of for() loop. <R> testarr<-matrix(1:30, nrow=5) rownames(testarr)<-letters[1:5] colnames(testarr)<-LETTERS[1:6] apply(testarr,1,function(x) {x11(); barplot(x)}) #the funcion used is actually more compex, but it doesn't matter </R> Now, how I can propagate

Dear List, I have found that moving the csv file to [working directory]\data directory solves my "problem", the file was loaded correctly. But I thought that R serches in all packages\data AND the [workdir]\data dirs, as mentioned in help. >?data Is this as problem or am I missing something important? (the latter is more probable :), but then why the behaviour is different from

Dear List, I frequently use the data() function to load csv files (with separator ";") into R session, typically data(myfile) loads myfile.csv from my working/data directory into R. Now, in 1.4.0 version, everything works as expected, but with one difference: The values readed in older versions in "num" mode are now readed as "int" mode, converting the values

Dear List, is there an elegant (or even not elegant) way how to transform dissimilarity or distance matrix A (or, in general, arbitrary symmetrical matrix) by transposition of rows and columns into a form closest to "block diagonal" matrix B? The matrix A is adjusted the following way A[A<epsilon] <-0 #(epsilon is given "small" number) B: (in its ideal form)

Dear R users, The package proptest (http://www.davidkraus.net/proptest/) has been recently released to CRAN. The package provides functions for testing the proportional hazards assumption in the Cox model for right censored survival data. Two types of tests for identifying nonproportional covariates are implemented: * data-driven Neyman type smooth tests (using both nested and all-subsets

Anyone know of a package for numerically estimating lambda(3) and lambda(4) using location, position, skew and kurtosis estimates. I have a distribution and would like to use the gld package to do some simulations of the distribution, but need the lambda estimates to feed into gld. I have a program in Maple, which I may convert to C code for use in R, but before moving down that road I

I'm experiencing segmentation faults from time to time that abruptely end my R sesion. In such cases, is there any way to recover the work done? (i.e., is there any temporal file that I could use?)

What is the generally accepted way to put certain math symbols into plain text email? For example, how does one convey the "is exactly equal to", "is approximately equal to", and "delta" symbols in a standard text-based (e.g. Courier) font? Dr. Marc R.

Hi all, this is OT, but maybe someone can give me a clue. I've got data from eye tracker experiments (750 data points). These figures show how the data lock like |** * ***** |*** ****** | ** **** | * * | | * * | | * |-------------- |--------------- Y axes display velocity, x axes display time, * are the data points.

Hello! I use the version 1.4.0 for Windows. I have made boxplots but only half of the symbols (three letters each) show up on the X-axis? How t can one change their size or orientation so that all show up? I attach the pdf file to illustrate better the problem.

Hi, This is a very trivial question, and I do not know why I cannot remember the answer at all! How does one get the entire system information (which OS, R version....etc) using an R command?

Greetings, I wonder if someone could point me towards a more elegent solution than what I"ve kluged together. I have a vector "samp1" of 296 integers. They are sorted in ascending order and the numbers range from 177 to 228,953. I'd like to specify N non-overlapping intervals covering the range from 0 to 229,354 and then for each range, count the number of integers from samp1

Dear list Having read through all the archives of the mailing lists, I've had no luck finding the answer to my problem. I am running a for(i in 1:n) loop and am creating a matrix, p, for each of the n observations. This matrix p is a 2x1 matrix. I am then doing the following: diagp<-diag(c(p[1,1],p[2,1])) to create a matrix with the elements of P on the diagonal (i.e. a 4x4 matrix).

This is no doubt trivial but after searching the help files and the web, I cannot seem to find it. 1) How do I convert 'hgt' into 'HGT' in R? 2) How should I have used the help facilities to find this? At the end of the day, all I want to do is case insensitive string matching... i.e. 'if ("HGT" == 'hgt') print('this should be true')' I tried

The cells are interpreted as counts, so by scaling you're analyzing a different experiment (one with fewer observations). So the chi-squared value will change (the terms (O-E)^2/E in the statistic scale linearly ignoring rounding and "Yates' continuity correction"). The chisq.test on the original data is a test of association. Conventionally you decide ahead of time on a

Dear useRs, There is a new version 0.1-2 of the package surv2sample available on CRAN. Users of the previous versions should update because a bug in the function cif2.ks has been fixed. General information about the package: surv2sample provides various two-sample tests for right-censored survival data. Three main areas and corresponding methods are: * comparison of two survival

Hi, I wonder if it is possible to create an DLL or EXE file performing R procedures. Instead of running R, reading data and calling some procedures, I would like to use R functions in the following way: "C:\linearRegression.exe data.txt" which would produce let's say file "output.txt" with the results. Is there some way how to do it? Thanks a lot. Pavel Vanecek
