Sys.getenv
I am running R-1.3.0 on Solaris 8: Under Solaris I do setenv dendro_us hoffmann echo $dendro_us gives back: hoffmann which is correct. When in R I do: Sys.getenv("dendro_us") I get dendro_us "" which is NOT correct: Inverse effect (taken from help of Sys.getenv) Under R: print(Sys.putenv("R_TEST"="testit", ABC=123)) [1] TRUE TRUE

minimization
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.

extraction
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

scan
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

HDF or netCDF
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)?

crosstab means
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

differential equations
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.

Re: R vrs S
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

loops
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

reading big arrays from C
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

R-beta: cran
Hi, the contributed section of CRAN has source code in C, etc. I am using RApril in Win95, How should one compile these programs? - with Watcom C10? - is 'lcc' the free 32 bit compiler usable? - Is 'load.dll' available? - If load.dll works, does it works with 16 bit dll's or it needs 32 bit dll's?

Read.table
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
