Hello, I want to try the Design and Hmisc library from FE Harrell but, i have trouble with the copyright for the library Hmisc : in the home of the author : http://fharrell.biostat.virginia.edu/s/unix/ in the file Hmisc.README ###COPYRIGHT NOTICE ###You may not port code in the Hmisc library to R. Aie, Why ???? ###You may distribute these functions freely as long as you do so without

On Fri, 14 Nov 1997, Jim Lindsey <jlindsey at luc.ac.be> sent an email to r-devel describing his first shot at porting Design and Hmisc to R. A few days later, his port snapshot of Design was uploaded to CRAN's src/contrib/devel area, and has since been available from there. A few weeks ago, Andreas Weingessel <A.Weingessel at ci.tuwien.ac.at> had a look into porting Hmisc to R

I noticed that apply is VERY SLOW when applied to a "large" dimension as for example when computing the row sums of a matrix with thousands of rows. To demonstrate it, I did some benchmarking for different methods of computing the row sums of an nx10 matrix with n =3D 2000, ..., 10000. The first method (M1) I used is the normal apply command: y <- apply(x,1,sum) The second method

I have the following problem. I have some multidimensional data points "x" and a curve "fit" fitted to these points. How can I combine R> pairs(x) and R> pairs(fit,panel=lines) in one plot, so that I can see how good the curve fits the data? A command like R> pairs(x, panel=function(x,y) {points(x,y); lines(lowess(x,y))}) does not work, since I fit the curve in all

### I got bit again by the same bugs I wrote about a year ago. ### The bugs are related to matrices and arrays of lists. ### 1.

Hello all R users and developers! In the "Notes on R" I have found the following information: (page 60, 13-th footnote) "... a better solution is to use the fig() driver (available from statlib) and use a conversion program, such as fig2dev, to convert the resultant fig code to Encapsulated Podtscript." I was very glad to read it, because I'm often forced to use

I work with Windows, R version 2.4.1 I'm trying to do a discriminant analysis and, in trying to figure out how to do it following the example from R help, I'm getting an error that says 'subscript out of bounds'. I don't know what this means and how to solve it (I'm very new with R) I'm doing everything in this made-up test matrix: group var1 var2 var3 1 1

Dear all, I searched the mail archives and the R site and found no guidance (tried "merge", "cbind" and terms like "coalesce" with no success). There surely is a way to coalesce (like in SQL) columns in a dataframe, right? For example, I would like to go from a dataframe with two columns to one with only one as follows: From Name.x Name.y nx1 ny1 nx2 NA

Hi, I would like to draw 10 uniformly distributed sample points from a circle with redius one and centered at (0,0). Is there any R function to do that?   Thanks, [[alternative HTML version deleted]]

This is my first post to this list so I suppose a quick intro is in order. I've been using SPLUS 2000 and R1.6.2 for just a couple of days, and love S already. I'm reading MASS and also John Fox's book - both have been very useful. My background in stat software was mainly SPSS (which I've never much liked - thanks heavens I've found S!), and Perl is my tool of choice for

In S it is possible to "split" a matrix into its rows, using split(matrix, 1:number_of_rows). This is not possible in R. Example: R: R> split(matrix(rnorm(1:20),4, 5), 1:4) Error in split(x, as.factor(f)) : argument lengths differ S: > split(matrix(rnorm(1:20),4, 5), 1:4) $"1": [1] -0.1804794 0.5269439 0.6248224 -0.3243427 -1.2987407 $"2": [1] 0.9384254

Sirs, may be that a fault exists in the file "postscript" under "r documentation" which contains "Notes on R:A Programming..." at http://www.ci.tuwien.ac.at/R/contents.htm| I did not succeed in reading and printing it. Can You help me? Many thanks in advance. F.Petronio petronio at univ.trieste.it

Dear R-Users and Developpers, Currently R does not include functions to compute the skewness and kurtosis. I programmed it myself in the following way, but probably *real* programmers/statisticians can do that better: mykurtosis <- function(x) { m4 <- mean((x-mean(x))^4) kurt <- m4/(sd(x)^4)-3 kurt } myskewness <- function(x) { m3 <- mean((x-mean(x))^3) skew <-

Colleagues, Thanks for the suggestions concerning reading matlab files into R 1. Regarding documentation for the format of matlab files, please see two manuals that I picked up from the matlab websites. The name of the files are: api_guide.pdf api_ref.pdf Use your web browser to access these files in my FTP directory <ftp://ftp.niwa.cri.nz/incoming/mcclatchie> under the appropriate

My attempt to get R running in Windows 3.11 didn't go very far. I have read the FAQ and install.tex carefully. What am I missing? Here is the step: 1. From statlib I got rexe.zip (and rbeta.zip, but this one seems for windows 95 only?). 2. On unzipping I got 8 files, including rb1.exe, and a sub- dir win32s, which I copied to windows/system. (There is no setup.exe,
