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

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

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

Hello all, Does anyone know of an R proc to export matrices or data frames (preferably with row and column names) directly into LaTeX table output?

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).

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, 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)

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

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

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

Thanks to all who response my problem. Here are my summary : 1. from Dirk Eddelbuettel <edd at debian.org> We could try a mixture of normals -- ie flip a coin (use a uniform with some cutoff c where 0 < c < 1 ) to choose between N(0, sigma_1) and N(0, sigma_2). 2. from Michaell Taylor <michaell.taylor at reis.com> We could use the gld library to specify the lambdas of

Hi All, I would like to work with symbols referenced by strings: I would like to manipulate data/symbols referencing to them by the string name of the symbol. An example will be clearer. Let's I get a time series through quantmod > getSymbols("GLD") This will create a new symbol GLD with the relevant data. I have tried to rename the column names as follows: >
