Thanks, Mark - I'm taking up your invitation to forward your message to the list just because it gives us some valuable data on (1) how long the behavior has been around, and (2) how many other people (don't) understand the behavior, and (3) how we might fix or work around it. I notice some other people also seem to be diffident about posting on R-devel; perhaps I should conclude that

The "r-devel snapshot build" 78175 on Windows--- a dot-exe installer--- seems to be missing a couple of files in its bin/i386 folder: Rterm.exe and Rgui.exe. Both are present in its bin/x64 folder (and in the i386 folder for current R). NB the lack of i386/Rterm.exe affects even the x64 version, since package installation seems to use it for testing loadability under both architectures

Dear R-devel When 'install.packages' runs, it updates all html files in all packages. Mostly, there seems to be no actual change to the html file contents, but the date/time does change. This has causing been me a bit of trouble, because I keep synchronized versions of R on several different machines, and whenever I install a package, many MB of file transfers are required; my slow upload

There is a bug in `predict' whereby the order of variables sometimes gets re-arranged compared to the original fit, and then disaster results. Specifically, the 'variables' and 'predvars' attributes of a 'terms' object get out of synch. This only happens when the terms in the original formula get re-ordered during fitting: test> scrunge.data_ data.frame(

Dear R-Devel, I was attempting an exercise in Hadley Wickam's book "Advanced R". The exercise is to find the generic with the greatest number of methods. I found that 'methods(`|`)' produces a list of length 2506, in R 3.3.1. Similar behavior is found in 3.4.0. It seems to include all functions and methods. I imagine something is being passed to "grep" without

Hi I'm trying to implement something similar to the following R snippet using C. I seem to have hit the wall on accessing class slots using C. library(fPortfolio) lppData <- 100 * LPP2005.RET[, 1:6] ewSpec <- portfolioSpec() nAssets <- ncol(lppData) setWeights(ewSpec) <- rep(1/nAssets, times = nAssets) ewPortfolio <- feasiblePortfolio( data = lppData, spec = ewSpec,

# r-bugs@r-project.org `predict' complains about new factor levels, even if the "new" levels are merely levels in the original that didn't occur in the original fit and were sensibly dropped, and that don't occur in the prediction data either. (At least if `drop.unused.levels' was set to TRUE, which the default.) test> scrunge.data.2_ data.frame( y=runif( 3),

I'm trying to get a reference to this object in C SWX.RET[1:6,c("SBI,"SPI","SII")] While i am able to access and use a plain SWX.RET object, I'm getting confused on how to create an object with the array subscripts like above. Here is what I tried to do. It doesn't work because "[" is obviously not an operation or function on SWX.RET. So how do I

Hi, exists("foo", inherits=TRUE) check whether an object named "foo" exists, and get("foo", inherits=TRUE) retrieves it. I'm looking for a similar function to exists() that returns the environment where the object "foo" exists, iff at all. If not found, NULL is returned. Does that exist? EXAMPLE #1: > sample2 <- base::sample > env <-

> Shield<SEXP> res(Rcpp_fast_eval(Rf_lang2(asEnvironmentSym, x), R_GlobalEnv)); The call should be protected before evaluation though. So more like: Shield<SEXP> call(Rf_lang2(asEnvironmentSym, x)); return Rcpp_fast_eval(call, R_GlobalEnv); Best, Lionel On 3/23/20, Dirk Eddelbuettel <edd at debian.org> wrote: > > > On 23 March 2020 at 17:07, Ben Bolker wrote: >

Hi, Im currently trying to debug a 'error in unprotect: stack imbalance' problem and I am curious about two basic questions on the use of PROTECT and UNPROTECT, which I could not figure out: - which objects have to be protected, namely, if the code is something like: SEXP fun, e; /* get the expression e ... */ fun = eval(e, R_GlobalEnv); /* or like this?: PROTECT(fun = eval(e,

Hello, I would like to read sets of files within a folder, perhaps using recursive methods. Right now, I rename the files before import. It would be even better to do this without renaming files, without providing explicit filenames, perhaps by importing files based on chronology, and translating each filename into a header? Please excuse my ignorance, and help cure my clunky programming

Dear all, when working on a project with embedded R, I found out that R-2.0.0 causes a problem where older versions worked OK. Rf_findVar(...) causes the following error when used to find a generic function (such as print): fun = Rf_findVar(...); R_tryEval(fun, ...); Error in function (object, ...) : Invalid generic function in usemethod Alternatively, using Rf_findFun(...) seems OK in this

Hi All, I was reading the R extension manual section 5.11 ( Evaluating R expression from C) and I tried to build a simple call to the sum function. Please see below. call_to_sum <- inline::cfunction( language = "C", sig = c(x = "SEXP"), body = " SEXP e = PROTECT(lang2(install(\"sum\"), x)); SEXP ans = PROTECT(eval(e, R_GlobalEnv)); UNPROTECT(2); return

Unfortunately, I don't see how it will allow me to search environments similarly/in the same order as exists/get(..., envir, inherits=TRUE) does it. getAnywhere() will search everything

I think recreating tempdir() is ok in an emergency situation, but package code should not be removing tempdir() - it may contain important information.
