We are running our * server as a virtual PBX for 6 companies. I am having all of the Allison prompts plus our own custom IVR prompts being re-recorded for each company, in a different voice (marketing thing) with a different personality (perky, corporate, earthy) . I'm curious if someone could point out a dirty trick to get the voice to play right, for internal and external callers,

R Users: I am trying to estimate a model of fertility behaviour using birth history data with maximum likelihood. My code works but is extremely slow (because of several for loops and my programming inefficiencies); when I use the genetic algorithm to optimize the likelihood function, it takes several days to complete (on a machine with Intel Core 2 processor [2.66GHz] and 2.99 GB RAM).

Hello, I was trying to build some functions which I would like to integrate over an interval using the function 'integrate' from the 'stats' package. As an example, please consider the function h(u)=sin(pi*u) + sqrt(2)*sin(pi*2*u) + sqrt(3)*sin(pi*3*u) + 2*sin(pi*4*u) Two alternative ways to 'build' this function are as in f and g below: coeff<-sqrt(1:4)

I reported the following vulnerability to AUSCERT, but they weren''t interested. People on this list might be, though! GNU tar is lazy about file creation modes and file owners when unpacking a tar file. Because GNU tar defaults to creating files owned by the userid running tar when the username is not found on your system, it can be possible to inadvertantly create setuid root

This is probably a simple problem but I don't see a solution. I have a data.frame with a number of columns where I would like 0 <- NA thus I have df1[,144:157] <- NA if df1[, 144: 157] ==0 and df1[, 190:198] <- NA if df1[, 190:198] ==0 but I cannot figure out a way do this. cata <- c( 1,1,6,1,1,NA) catb <- c( 1,2,3,4,5,6) doga <- c(3,5,3,6,4, 0) dogb <- c(2,4,6,8,10,

As part of carrying out a complicated maximum likelihood estimation, I am trying to learn to program likelihoods in R. I started with a simple probit model but am unable to get the code to work. Any help or suggestions are most welcome. I give my code below: ************************************ mlogl <- function(mu, y, X) { n <- nrow(X) zeta <- X%*%mu llik <- 0 for (i in 1:n) { if

Hello, I am looking into description of surf.ls(spatial) and see under value $beta - the coefficients. When I use polynomial of degree 2 to fit surface I expect to get 4 coefficients: z = a_1 x^2 + a_2 xy + a_3 y^2 + a_4 What do beta really stand for and why do I get $beta vector of length 6? Thakns, Mark

I am working with a somewhat complicated structure in which I need to deal with a function that takes ``basic'' arguments and also depends on a number of parameters which change depending on circumstances. I thought that a sexy way of dealing with this would be to assign the parameters as objects in the environment of the function in question. The following toy example gives a bit of the

Hello I have the following data frame which I read from an EXCEL file, and when i try to call one of its columns with a space in their names I am not being able to. For example if I do EURODOLLAR$ED1.Comdty Date I obtain the following error: Error: inesperado símbolo en "EURODOLLAR$ED1.Comdty Date" I have also tried using . or _ instead of the space and have obtained no succes. How do I

Hi, I am trying to use boot() to refit an ordinal logit (polr in MASS) model. (A very basic bootstrap which samples from the data frame without replacement and updates the model.) I need to extract two statistics per run (the coefficients and zeta) and I tried concatenating them into a single vector after fitting, but I get the following error: Error in "[<-"(*tmp*, r, ,

Dear R users, I have the following codes: zeta <- rep(1,8) n <- 7 for (i in 1:2){ beta <- zeta[1:n+(i-1)*(n+1)] print(beta) parm <- zeta[i*(n+1)] print(parm) } ################### The output is as follows: [1] 1 1 1 1 1 1 1 [1] 1 [1] NA NA NA NA NA NA NA [1] NA ####################### The outcome I want to get is: [1] 1 1 1 1 1 1 1 [1] 1 [1] 1 1 1 1 1 1 1 [1] 1 How could I get the

Hi all, I fear I can't rely on "open (path, O_CREAT | O_EXCL)" behaviour on samba share. The libc's doc says: If both `O_CREAT' and `O_EXCL' are set, then `open' fails if the specified file already exists. This is guaranteed to never clobber an existing file. But this isn't probably true on network filesystems. When I run this tiny program on
