similar to: Problem with factor state when subset()ing a data frame

Hi folks, I am running into a problem when calling subset() on a large data.frame. One of the columns contains strings which are used as factors. R seems to automatically factor the column when the data.frame is contstructed, and this appears to not get updated when I create a subset of the table. A minimal testcase to demonstrate the problem follows: sample <- data.frame(c("A",

I am trying to clear up all the "NOTE"s before a CRAN submission, but am a bit confused about this one.?? What is it complaining about -- that it doesn't like my name? ... * checking for file ?deming/DESCRIPTION? ... OK * this is package ?deming? version ?1.4-1? * checking CRAN incoming feasibility ...

I've created some Splus code for a microarray problem that - needed to be in C, to take advantage of some sparse matrix properties - uses a cholesky decompostion as part of the computation For the cholesky, I used the cholesky2 routine, which is a part of the survival library. It does just what I want and I'm familiar with it (after all, I wrote it). In Splus, this all works

In one of my plot functions it is convenient to use clipping to restrict the range of some output. But at the end of the function I'd like to turn it off, i.e., so that a subsequent use of legend(), text() or whatever is not affected. I don't quite see how to do this -- it seems that the only way to turn off clip is with a new plot. -- Terry M Therneau, PhD Department of Health

Is there a way to include the compiled version of a vignette in the doc directory but mark it to NOT be rerun by CRAN??? I think I remember that this is possible, but have forgotton how.?? (It might even be a false memory.) Terry T. Background:? Beth Atkinson and I are splitting out many of the vignettes from the survival package into a separate package survivalVignettes.? There are a few

Naras presented something with similar functionalities using SVG a couple of years ago, and since then the svgdevice package had been made available. I do not know SVG myself, but according to Naras, it's all possible.

I haven't done any R memory debugging lately, but https://www.mail-archive.com/rcpp-devel at lists.r-forge.r-project.org/msg10289.html shows how I used to have gdb break where valgrind finds a problem so you could examine the details. Also, running your code after running gctorture(TRUE) can help track down memory problems. -Bill On Wed, Feb 7, 2024 at 12:03?PM Therneau, Terry M., Ph.D.

I cloned therneau/survival and the installation failed since there is no definition for exported function survfit(). A file seems to be missing - there is survfit0() and survfit0.R but, compared to CRAN, no survfit.R.

?I've hit a roadblock debugging a new update to the survival package.?? I do debugging in a developement envinment, i.e. I don't create and load a package but rather? source all the .R files and dyn.load an .so file, which makes things a bit easier. ? Running with R -d "valgrind --tool=memcheck --leak-check=full" one of my test files crashes in simple R code a dozen lines

I found an issue with the data() command this evening when working on the survival package. 1. I have a lot of data sets in the package, almost all used in at least one vignette, help file, or test.? As a space saving measure, I have bundled many of them together, i.e., the file data/cancer.rda contains 19 data sets, many of them small. The resulting file (using xz compression) is quite a bit

I'm trying to plot pspline'd explanatory variables from coxph() models as per Therneau and Grambsch (Modeling Survival Data: Extending the Cox Model). They have s-plus functions for this at: http://www.mayo.edu/hsr/people/therneau/book/sfunction/gamterms.s http://www.mayo.edu/hsr/people/therneau/book/sfunction/plotterm.s I'd like to make these plots in R, but they make use of non-R

Yes, that is exactly the problem.? The code found in the "config" script is never run.? But why doesn't it get run?

Wolfgang, It is common to handle relative risk problems using Poisson regression. In your example you have 8 events out of 508 tries, and 0/500 in the second data set. > tdata <- data.frame(y=c(8,0), n=c(508,500), group=1:0) > fit <- glm(y ~ group + offset(log(n)), data=tdata, family=poisson) Because of the zero, the standard beta/se(beta) confidence intervals don't work.

After an extremely long gestation, a new version of the coxme package is now available on CRAN. This function fits very general mixed-effects Cox models using an lmer-like syntax. For instance here is a model that fits a random treatment effect, using data from a multi-study collaboration. fit <- coxme(Surv(pg.time, pg.stat) ~ stage + trt + (trt|site) + stata(site), data=

It's hard to diagnose this without your package sources / a reproducible example. Shot in the dark: one thing worth checking is that you don't have an entry in your `.Rbuildignore` that's removing files you don't expect it to (maybe that's causing R to strip out the 'doc/index.html' file) Kevin On Fri, May 15, 2015 at 12:54 PM, Therneau, Terry M., Ph.D. <therneau

You can legally cast a function pointer to another function pointer, where the signatures differ. (It is not legal to cast between data and function pointers.) I would make typedefs for the various signatures, as the casting syntax is more readable then.
