I am trying to use the sas.get function to bring a SAS dataset into R. After calling the sas.get function I got an error message stating that 'sas' is not a recognized internal or external command, etc. I am guessing that I need to specify the internal command to invoke SAS in the sasprog option for the sas.get function, but I don't know how to determine what that command might be.

I have a dataset at a hospital level (as opposed to the patient level) that contains number of patients experiencing events (call this number y), and the number of patients eligible for such events (call this number n). I am trying to model logit(y/n) = XBeta. In SAS this can be done in PROC LOGISTIC or GENMOD with a model statement such as: model y/n = <predictors>;. Can this be done

Dear all, I am trying to find a suitable R-function for parametric proportional hazard regressions. The package survival contains the coxph() function which performs a Cox regression which leaves the base hazard unspecified, i.e. it is a semi-parametric method. The package Design contains the function pphsm() which is good for parametric proportional hazard regressions when the underlying base

Does anyone know of a function that computes the necessary sample size to reject a null median survival in favor of a given alternative median survival in a one arm trial?

I read the posts about augPred with lme, but does anyone know if there is a correlate for augPred for lmer? Specifically, I want to be able to use it to plot projections for all groups in an lmer class object using plot(augPred(lmer.object)). Thanks, Kyle *************************************** J.

Does anyone know if for clinical studies the FDA would accept statistical analyses performed with R ? Delphine Fontaine

A few months ago, I posted a query regarding code for a sample size estimate for a one arm survival trial. Below is some code I created to calculate such an estimate - perhaps it may be of some use. #cox.pow computes sample size for a one arm survival trial. med.0 is the null median #survival, med.a is the alternative median survival, a.time is the accrual time, and #f.time is the follow up

Is there a simple way to decompose the upper triangle of a correlation matrix to a linear list; For example: X Y Z X 1 2 3 Y 2 1 4 Z 3 4 1 so you get a list like: xy 2 XZ 3 YZ 4 I suspect you can do it with a matrix transformation, but that beyond me at present.

Hello R folks, Does anybody have code to share for generating (via simulation) clustered data? The type of data I am looking to simulate would allow fitting of a multilevel model with random intercepts. I looked at the mvtnorm package but am not quite sure how to create clusters. (Can this be done by simply changing the seed?) If somebody could point me where to look for the relevant

Dear all, There have been a variety of discussions on the R list regarding the use of R in clinical trials. The following post from the STATA list provides an interesting opinion regarding why SAS remains so popular in this arena: http://www.stata.com/statalist/archive/2008-01/msg00098.html Regards, -Cody Hamilton

Hi, Is there any existing functions to open an HTTP connection and HTTP POST some R data? like <form method="post" enctype="multipart/form-data"> etc. </form> but within R.

Hi, I have a student trying to run R on an Apple (OS 10.3.9). She tried to cut-and-paste the data via the code: data<-read.table(pipe("pbpaste")) But she keeps getting the error message: 'error in pipe("pbpaste"): pipe connections are not available on this system' I do not know much about using an Apple. Has anyone run into this before? Does anyone have any ideas

Hello all, We currently have a java web utility that allows multi-threaded data analysis using S+. We want to migrate it to R. However, the guy who preceded me here left some documentation indicating that he couldn't implement it because R didn't support threading. Also, he noted that the R-Java interface(org.omegahat.R.Java.REvaluator) wasn't thread safe even if R was. Can

Hi All, I've been fiddling around with various ways to estimate the popularity of R, SAS, SPSS, Stata, JMP, Minitab, Statistica, Systat, BMDP, S-PLUS, R-PLUS and Revolution R. It's not an easy task. You can see what I've come up with so far at http://r4stats.com/popularity . I'm sure people will have plenty of ideas on how to improve this, so please let me know what you think.
