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, I saw some ref to R on HDF site and found some e-mails regarding them on Feb. Has there ben any developement on either of these software (HDF or netCDF)? I am primary interested in NT side, but Unix side will help to some degree. Thanks much in advance, ************************************************************** S. Hoon Yoon (Quant) Merrill Lynch

Hi R experts, Can somebody suggest what can be wrong? PIII with 128 Mb RAM Using R 1.1 in Win98, the latest version downloaded yesterday.

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 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

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

hello. I am trying to read a big file with different sections each with a different format, actually it is a map in format *.e00 of MapView. I can read the whole file with no problems from R using scan() but it takes too long, some files are 50 meg and have to be read line by line to catch the section codes. So if I do the reading from C would it be faster? if it is, how do I manage with the

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.

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

After reading the comments on my problem of floats turned into factors i went back to my original file in Excell, save as csv, then reopen with a 'different' text editor to delete all spaces and now the files are read OK. I assume that when I stripped all the spaces from the file a funny character, non printable, crept in. Thanks to B.D.Ripley,M.Maechler,P.Dalgaard and T.Lumley for

hello, I am using R1.2.2 on win98 with 64 meg of RAM I try to read a big csv file and get the error : a <- read.csv("c:/all2.csv",header=T) Error: vector memory exhausted (limit reached?)

I also have several packages in my RW0633 in Windoze and I would like to keep them in one place when I update the R system.
