Dr. Frank E. Harrell, Jr., Professor and Chair of the Department of Biostatistics at Vanderbilt University is giving a one-day workshop on Regression Modeling Strategies on Friday, April 29, 2005. Analyses of the example datasets use R/S-Plus and make extensive use of the Hmisc library written by Professor Harrell.The workshop is sponsored by the Southern California Chapter of the American

Great news! Having spent a significant amount of time porting/mantaining some packages on S4/Splus 5.x and R, I'm interested in your experience as you port Hmisc and Design; I'd like to know of your progress in order to help improve available R/Splus portability tools both at the C and the S language code. These tools include the package SLanguage written by John Chambers, and

Hello, I want to try the Design and Hmisc library from FE Harrell but, i have trouble with the copyright for the library Hmisc : in the home of the author : http://fharrell.biostat.virginia.edu/s/unix/ in the file Hmisc.README ###COPYRIGHT NOTICE ###You may not port code in the Hmisc library to R. Aie, Why ???? ###You may distribute these functions freely as long as you do so without

I'm writing a package that interfaces to the FAME database, via a library of compiled C routines accessible through a Linux .so file. My .onLoad() function loads the .so like this: dyn.load("/opt/fame/timeiq/lib/linux_x86/libjchli.so", local = F) and after that I also load my own fame.so via library.dynam("fame", package = "fame") The code in fame.so uses

A couple of months ago, I asked Frank Harrell (fharrell@virginia.edu), the author of the Hmisc S-Plus library, about the reason for his "No porting to R" requirement. I may have previously posted his reply, but I don't see it in the archives, so I'll send it again. This is a edited version of our email conversation: Gregory R. Warnes: The license to the Hmisc library

Dear All, I wonder whether anyone has an experience with FAME package written by Jeff Hallman. All my attempts to send him the following problem report did not succeed (the mail system says that my e-mail could not be delivered), so I turn for help to this list. I tried to use your FAME package written for R, but somehow I cannot get it working. I am using Windows XP and the newest R

One hassle I could do without is the necessity of writing C wrapper functions like this: void fameInit(int *status){ cfmini(status); return; } when I want to call a library function (cfmini, in this case) that takes an int argument. The .C interface only lets me pass a pointer to an int, rather than the int itself. Is there any chanch that .C could be enhanced to allow passing arguments by

My fame package has to link to the libchli.so that comes with FAME. However, FAME is now supplying both 32 and 64 bit versions of the library. The 32-bit version is $FAME/hli/libchli.so while the 64-bit version is $FAME/hli/64/libchli.so. To set the right flags, it seems that I need to know, from within configure.ac, whether the R installation is 32 bit or 64 bit. Is there a way to detect this?

Dear R-help, I am having a problem with the interpretation of result from validate.cph in the Design package. My purpose is to fit a cox model and validate the Somer's Dxy. I used the hypothetical data given in the help manual with modification to the cox model fit. My research problem is very similar to this example. This is the model without stratification: > library(Design) > f1

Dear list, I am relatively new to ordinal models and have been working through the example given by Frank Harrell in the predict.lrm {Design} help All of this makes sense to me, except for the responses, i,e how do i interpret them? i would be extremely grateful if someone could explain the results? First i establish the date and model - > y <- factor(sample(1:3, 400, TRUE), 1:3,

Hi Dirk, I didn't capture the output but using Focal I got an error with RcppParallel trying to open a file that wasn't found, and plotly::ggplot() would not render a ggplot graph. 20.10 is working well for me otherwise.

I have a few functions, such as screenWidth() and screenHeight(), which I have been able to implement for a Unix/Linux environment, but not for Windows. (Does anyone know how to find the screen dimensions in Windows?) The Writing R Extensions manual tells me how to include platform-specific sections in documentation, and even how to have platform-specific help files. But it doesn't say
