Hi! I was trying to implement a probit model on a dichotomous outcome variable and found that the predictions were outside the (0,1) interval that one should get. I later tried it with some simulated data with a similar result. Here is a toy program I wrote and I cant figure why I should be getting such odd predictions. x1<-rnorm(1000) x2<-rnorm(1000) x3<-rnorm(1000)

...i = size of argument block edi = address of argument block ecx = callee object and on return eax = status code ebx = possible one-shot continuation ecx = returned value edx = returned reference I only want it to work in a JIT fashion so no persistence in bitcode files is necessary. Thanks, Raja Mukherji

Hi R users, I am looking to numerically solve a dynamic program in the R environment. I was wondering if there were people out there who had expereinced success at using R for such applications. I'd rather continue in R than learn Mathlab. A concern that has been cited that may discourage R use for solving dynamic programs is its memory handling abilities. A senior researcher had a lot of

Hello, I need to write out a data matrix as a STATA 7 file and this happens perfectly with write.dta(), except I cannot seem to export the labelnames to Stata. So far I have tried the following: # X is the data matrix that is to be exported attributes(X)$var.labels <- c("apple", "banana", "cat") write(X, filename = "text.dta", version = 7) When i

...; error (See the output message on the bottom). I get the same error when running "RCMD check". My system is: Windows 2000, R version 2.0.1, MiKTeX version 2.4. I do have a Rd.sty file in R_HOME/share/texm directory. I looked through newsgroups for any related discussions and found Arnab Mukherji reporting the same problem on Dec 23 2003 (Subject: "[R] Rd.sty not found -"). In reply Prof. Brian Ripley suggested the following: It should be looking in TEXINPUTS, as is the point of the following in the check script $ENV{'TEXINPUTS'} = env_path(&file_path($R::Vars::R_HOM...

Hi ! I am trying to get at the covariance of the predictions of a linear model. Suppose the we have: > x<-runif(1000) > y<-2 + 25x*x +rnorm(1000) > lm1 <-lm(y~x, data = data.frame(y = y, x=x)) > x.pred <-runif(10) > y.hat <- predict(lm1, newdata = data.frame(x=x.pred)) I was wondering how to get an estimate of the covariance of y.hat which would be a 10 x 10

Hi! I was just reading Uwe Ligges write up on extending R-WinEdt for Sweave from 2003; I was wondering if there were updates on it? Are people seriously thiking about it? I really use WinEdt a lot, and for not just R, and hence this kind of extension would be really cool for a whole range people. Just thought I put in a word for it in case this project is dormat, or people are thinking about

Hi I have been trying to get the R Extention supportware going for a while now and have been running to an error I cannot figure out. I am hoping someone here will recognize whats going on and what i may be messing up. After installing all the components - Rtools, Active Perl, and minGW I created the file structure using package.skeleton(name = "test") with only the functions i want

Hi: I just tried to install the patch for RWinEdt - there is an automated package ('SWinRegistry' ) which with the rwinedt patch on the CRAN site have to be loaded as packages from R using the local zip drive option. That works fine. The next step is to call the library(RwinEdt) and this does'nt work out ... the meesages i get are: >

Hi R-users, I had a minor issue while demonstating R that I can't explain. I am hoping someone will have suggestions. The only difference is a call to fix() in between that I made to ensure people were following me. However, that seems to have altered the way R code got executed. I was wondeirng if people have any insights. Arnab # When it does work x <-letters[1:10] marks

Hi I am still trying to wrap up a package using Rcmd (in windows 2000 professional with R 1.8.1). I have made some progress - and now at least Rcmd check works - it still giving me an error message when it creates latex help files though. Thus I get: c:\rpack> Rcmd check test * checking for working latex ... OK * using log directory 'C:/rpacks/test.Rcheck' * checking for file

Hi Has anyone used R to conduct confirmatory factor analysis? This email pertains to use of SEM. For context consider an example: the basic idea is that there are a bunch of observables variables (say study habbits, amount of time reading in the bus, doing homework, helping other do homework, doing follow-up on errors etc.) and one believes that all these variables maybe measured by two or
