My computer is a pentium 4 running at 2.4 GHz. My R is 1.7.1 I have written a program in R that calls C++. The program spends most of the time in C++ ( > 90% ). R basically deals with output and input. How slower can this be compared with the program I would get from rewriting everything in C++? Thank you.

Dear everybody! Are there algorithms for multinominal logit/probit available for R? Is it my fault that I cannot find these in CRAN?

Hi folks, I am planning to write some more time-consuming matrix manipulations in c++. What is the experience with the existing c++ matrix libraries? Do you have some recommendations? Are some libraries more compatible with R than the others? All suggestions welcome! Best, Ott

Can anyone explain me the following behavior: > 1:2/1 [1] 1 2 -- makes sense > 1:2/matrix(1,1,1) [1] 1 2 -- makes sense > 1:2/data.frame(a=1) a 1 1 -- why is this different?

Do I mess up something or is this a bug? If I define an S4 object that contains "factor", all the tests indicate that it is a factor but as.character.factor() complains of it being a non-factor... > setClass("Foo", contains="factor") > a <- new("Foo", factor(1:3)) > a Object of class "Foo" [1] 1 2 3 Levels: 1 2 3 > class(a) [1]

hi, i want to plot percentage values using barplot. everything works fine so far. giving a chance level of 50% i want to plot only the area above 50 percent. i can of course cut using ylim=c(50,100) but this does not work properly since i also see some of the area below 50%. thanks for suggestions, jan -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Hi R-devl, I'm still unable to force opening an *interactive* non-Rstudio platform-specific plot device on *unix* systems. dev.new() add a new argument 'noRStudioGD' in R 3.1.1. Thank you. It works for me when using RStudio on Windows, but on the unix system it opens a pdf device instead of an interactive device when using an interactive RStudio session (with R_DEFAULT_DEVICE

Hello, I am running a preliminary data-processing job on solaris. Basically, the program reads a large number of ascii-lines (about 1M) by blocks (size 25000 lines), selects suitable observations (around 5000) and writes the results into a dataframe for latter processing. The problem is that when I run the job interactively (in emacs/ESS), everything works fine. If I try to run it from shell

I would like to create a barchart that has vertical instead of horizontal bars. My goal is something similar to Figure 6.10 (p. 166) in "The Basics of S and S-plus," except for the orientation of the bars. I don't think bwplot() or xyplot() will work. Any suggestions?

Hi, I am trying to study R internal behaviour. So long, I have not succeeded to access the value of R strings from C. I use: void salvesta_tabel( SEXP data_frame, SEXP file ) { printf( "nimi %d\n", (R_CHAR)( file)); } and from the R side: salvesta.tabel <- function (x, file = "") { .Call( "salvesta_tabel", x, file) } When calling

Dear R People: Here is a very simple question, please: I have a data frame with the state name, state division, and population. Note: state division is something like Atlantic, Mountain, etc. I want to produce a table with the state division and the total of the populations for the states within that division. I've been messing with "table" but so far, no luck. This is R1.3.1,

Dear R-gurus, I would like to use a lapply on a kind of "bivariate" problem. I have a vector and a list, components of which are vectors, e.g. vec <- c(1,2,3) lst <- list(1, c(2,3), c(4,5,6)) I want to apply a function to each component of the list, using the corresponding component of the vector as a parameter. E.g. I want a list in the form list(lst[[1]] + vec[1], lst[[2]]

Dear All, we (Ott Toomet and I) would like to add functions for maximum likelihood (ML) estimations of generalized tobit models of type 2 and type 5 (*see below) in my R package for microeconomic analysis "micEcon". So far we have called these functions "tobit2( )" and "tobit5( )". Are these classifications well known? How are these functions called in other
