Hello, I am on win98 with R1.4 from BDR I have a directory structure like this c:\R\RW1040 c:\R\R_CRAN\Library C:\R\R_SRC\Library so Y put the new versions of R in RW... and I download the packages from CRAN into R=R_CRAN\library so they do not change from R version to version, R\R_SRC is for packages from other places than CRAN or for my own things Now if when R starts I say > library() I get

I've got a PhD student starting this year. She'll be working on data mining. She has asked for a reading list while she's still in her home country, which is a really good sign. Her cosupervisor and I don't (think we) have any problem with choosing things that are specifically about data mining, but there are some statistical ideas (sampling, exploratory-vs-confirmatory,

Hi, I got a code from S that uses 'nlminb' to minimize a function with constraints. Is there a similar function in R? Thanks. R.

Hi, Does somebody knows of the existence of a library of functions for solving differential equations, I need a solver for a system of non linear first order differential equations. I think there was something in IMSL but that was a long time ago and probably there are some new algorithms in the new now. Thanks for any pointers. . R.

Hello everybody I am trying to extract some observations from a data frame, ie the subjects that belong to a given group, and although t-test etc work if I try to obtain the number of subjects in the subgroup i get some funny numbers. All the subjects with NA for group are included in the subgroups 'group==1' etc. Is this a bug? for example in Windoze R : Copyright 2001, The R

Hello, I wrote the following function to compute multiple comparisons in a one way anova and randomized blocks anova. aov1 <- function(y,g,s=NULL,comp="mca",meth="Sidak") { # fun <- function(x) c(mean(x,na.rm=T),sd(x,na.rm=T),length(x[!is.na(x)])) # li <- length(unique(g)) cat(" Analysis of Variance with Multiple comparisons\n\n") cat("

Hello, I have a problem. I have to read a HUGE file which has to be line processed, so I would like to use scan like p <- scan(pfile,what=c(0,0,0,"",0,""),nlines=1) but it continues to read the first line, so I have to add a skip and increment the skip after each read. It takes forever to read a test file of 1 Mb, the real one is in 60's Mb Is there a way to read line

Hi R friends, I havent asked a silly question in a long time so here it is: Reading the last issue of Stat Can J. there is an article in a single degree of freedom test for non aditivity of interactions in anova tables with 1 obs per cell. The authors claim it is more powerfull than Tukey but for the case of multiplicative interaction, which is the alternative studied by Tukey. I tried to

I would like to obtain a crosstabulation of means(var, quantiles...) i.e. I have a data frame with Var-i, Var-j, Var-k, Var-X, var-Y I like to have the mean of Var-X for each combination of Var-i,Var-j. One solution would be: by(var-i,Var-j,mean(Var-x)) but I would like it better formatted and with mean,S.Dev,n for each cell? Does anybody have some function to do this or some ideas how to go

Hi, I am relatively new to R programming. I have Guido's version on a Win95 Pentium with 32 Mb RAM. I tried to compile the Package MIXREG of Rolf Turner in S to R almost everything works OK but he has a function po = partial outer product as follows: po <- function(a,b) { array(apply(b,2,"*",a),dim=c(dim(a),dim(b)[2]))) } in S-Plus given x = ( 1 1 1 2 1 3 1 4

I received several answer to my querry re reading zipped files, R.Gentleman, Liaw Andy, BD Ripley,J Holtman, A.Matt, and others, sorry if I missed your names. a- use pipe to run external unzip to a file and read from there b- use gzfile() to open directly a gzipped file c- use zip.file.extract() solution b works like a charm, unfortunately it open gzipped files and not zipped files, would it be

I just finished coding up a change to how code generation builds machine instructions. The change is in include/llvm/CodeGen/MachineInstrBuilder.h, where when you want to add a register, you have to specify a long list of booleans indicating if it's defined, implicit, killed, dead, or early clobbered. I don't know about you, but it was hard for me to read the source and understand what was
