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...

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...

Hi, I have a query about the following: CONTEXT: if we define: eq <- y ~ x1 + x2 then is.language(eq) returns true. this works perfectly with commands such as lm(eq,data=my.data) THE PROBLEM: Now I have a...

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...

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...

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...

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...

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...

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...

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...
