similar to: Finalizer function?

(Tried this query on r-help with no luck, maybe someone here can help?) I would like to call the 'RFinalizerEx' function that appears in Rinternals.h using ".Call". It worked for me in the past, but now I get an error message something like: 'call function name not in call table'. I'm using the 1.6.1 rpm from CRAN. Anyone know what's going on? Thanks. Tim --

I'd like to add an "on.exit" flag to "reg.finalizer". Is it possible to check out the source via anon cvs? (If so, which module is preferred for this sort of thing, and which diff flags?) Tim -- Timothy H. Keitt <tkeitt@mail.utexas.edu> University of Texas at Austin

Hello, I asked this question a little while ago ( https://stat.ethz.ch/pipermail/r-help/2008-April/158761.html ) but got no response. Can anybody explain to me the difference between /, :, and %in% in the definition of random effects in lmer, such as: (1|A/B), (1|A:B), (1|B %in% A)? My understanding is that (1|A/B) is the same as (1|A) + (1|A:B), but I have not seen this stated explicitly

Hello list, I'm trying to figure out how exactly the specification of nested random effects works in the lmer function of lme4. To give a concrete example, consider the rat-liver dataset from the R book (rats.txt from: http://www.bio.ic.ac.uk/research/mjcraw/therbook/data/ ). Crawley suggests to analyze this data in the following way: library(lme4) attach(rats) Treatment <-

I have executed a Repeated Measures ANOVA with one DV (latency) and one within subject factor (acoustic condtion: 3 levels) by bootstrapping my sampling distribution of F from the empirical sample distribution. I chose to resample because the sample distribution deviates from normality a lot. The overall F is significant and now I wish to decompose this with contrasts to ask if latencies to

Tim, What you're describing is a special case of the ALTREP framework/API that Luke Tierney, Tomas Kalibera, and I are working on putting into R. See my initial proposal to the DSC here: https://www.r-project.org/dsc/2016/slides/customvectors.html and the subsequent branch here: https://svn.r-project.org/R/branches/ALTREP/ where Luke and I have merged the ideas from that proposal with work he

Use R_RegisterFinalizerEx in your C code. See https://cran.r-project.org/doc/manuals/r-release/R-exts.html#External-pointers-and-weak-references This still gives you only "best effort"; for anything stronger you would need a different approach. In general, finalizers should only be used as a backstop, not as a primary resource management tool (in R or any other garbage-collected

Hello, We?re receiving reports of extremely slow rendering by users who are using the new geom_sf() feature in ggplot2. Importantly, this seems to be a graphics device issue, because the exact same plot takes vastly different amounts of time to render under different devices. We?re talking about 2 seconds vs. 100 seconds here, so not a small effect. In particular, the quartz device on OS X seems

I see some code in R to attach finalizers to external pointer references (Register[C]Finalizer). Anyone have an example of how to code the finalizer? R_RegisterCFinalizer accepts a C function, but I can't see how to get it to operate on the pointer, since the pointer is not passed to the function when its called. RegisterFinalizer takes an R closure, but how is it called from R (tried

Hi Folks, I have repeated measures for data on association time (under 2 acoustic condtions) in male and female frogs as they grow to adulthood (6 timepoints). Thus, two within-subject variables (Acoustic Condition: 2 levels, Timepoint: 6 levels) and one between-subject variable (Sex:male or female). I am pretty sure my distributions depart from normality but I would first like to simply run a

See R_RegisterCFinalizerEx() and set onexit to nonzero.

Hi all, I found that the finalizer of the externalPtr is not called when R is quitting. However, manually calling GC() works fine. This behavior is observed on devel R 2020-04-02 r78142 on Win and R 3.6.3 on Ubuntu. I make a reproducible package here: https://github.com/Jiefei-Wang/example Here is the detail of how to reproduce the problem, I create a temporary file in the package root path and

I'm just curious if anyone else has had problems with this configuration. I added the CRAN repository to apt and installed 2.5.0 with apt-get. I then did an install.packages("Rmpi") on cluster nodes. Rmpi loads and lamhosts() shows the nodes, but mpi.spawn.Rslaves() fails (something to do with temp files?). Rmpi works fine with the Edgy-native version of R (2.3.x) and installing

I can't seem to find this anywhere. How do I set the default CRAN repository _site wide_ on a linux box? What I want to do is eliminate the pop-up list of repository locations when using 'install.packages()'. I know how to do this for a single account. Modifying files in /etc/R does not seem to work.

Thanks Simon. I'll probably just switch to rocker when needing to debug in that case.

Tim, as a security precaution Apple has disabled the ability to debug notarized applications*. It means any software distributed on macOS Catalina (and they may have retro-actively enabled it for recent updates of Mojave) cannot be run in a debugger. If you want to debug R, you have to use non-release binaries that are not notarized and install them by hand, e.g.: curl -L

I'm adding things to the Windows RGui so that there's more control of the interface from within R. One thing I'm considering is giving access to the Graphapp window objects using external pointers. This raises the issue of finalization on both sides: - If someone creates a pointer referring to a window, then that pointer should be changed to NULL when the window is closed. - If
