Hello, Are there any recipe to handle serialization / deserialization of external pointers. I'm thinking about something similar in spirit to the way we handle finalization of external pointers. Currently, if we create an external pointer, save the session, quit R, then load the session, we get a null pointer. One way I'm thinking of is to have an environment in the

My sessioninfo is below and I have two questions about loading packages in R : #======================================================================= ============================================================= R version 2.4.0 (2006-10-03) i686-pc-linux-gnu locale: C attached base packages: [1] "datasets" "methods" "utils" "stats"

A newbie here - please forgive me if this is a basic question. We have an in house package built in R 2.2.1 (yes we're a little behind the times at our firm)and would like to rebuild it using R 2.5.1. However, when I try and build the package from source, I keep getting this error: Error in as(slotVal, slotClass, strict = FALSE) : no method or default for coercing "POSIXt"

Hi, I wanted a Q&D way to open a new graphics window but keep the focus in the console window (under Windows and the Rgui), so I wrote a line into my Rprofile.site file as follows: invisible(makeActiveBinding('newdev', function(...) dev.new(restoreConsole=T), .GlobalEnv)) (That is all on one line, incase the mailer re-parses it). This gives me a command "newdev" which

Greeting R-devel, I find myself wanting to attach an active binding to an existing object in the global environment (R 2.12.2), but there doesn't seem to be an easy way to do this: > x = 5 > makeActiveBinding("x", function(d) "hi", .GlobalEnv) Error in makeActiveBinding("x", function(d) "hi", .GlobalEnv) : symbol already has a regular binding

Helo, please look at the log below: after loading the fSeries library, I can not use the log function. Is this a bug or what am I doing wrong?

I'm just starting to have a look at LLVM, so forgive me if this is a simple question. What I'd like to do is use the JIT api to construct a "program" that calls a series of functions. In other words I'm wanting to translate a scripting language into some executable assembler where each primitive of my scripting language is implemented with a "normal" function.

Hi, I was wondering if this is expected behavior for active bindings in attached environments, or if this is a bug: > e <- new.env() > makeActiveBinding('x',function() 'foo',e) > ls(e) [1] "x" > attach(e) > search() [1] ".GlobalEnv" "e" "package:graphics" [4] "package:grDevices"

Hi R, Please see the below commands. The question is I can see the value of log(2) before loading the package fcalendar in R. But after loading the package, the 'log' function doesn't work. How to solve this problem? Also note that the function code differs before and after downloading the packages. > log function (x, base = exp(1)) .Primitive("log") >

A shorter reproducible example: example(makeActiveBinding) for (fred in 1:3) { 0 } ls() Both problems go away if you first do compiler::enableJIT(2) So looks like a bug in compiling the for loop. -Deepayan On Sat, May 23, 2020 at 5:45 PM Thomas Friedrichsmeier via R-devel <r-devel at r-project.org> wrote: > > Possibly just a symptom of the earlier behavior, but I'll amend my

Hello, Should active binding appear as such in ls.str. > makeActiveBinding( "xx", function(arg){ Sys.sleep(10) }, .GlobalEnv ) > ls.str() # takes 10 seconds xx : NULL What we see here is the result of the "setter" of the binding. I'm attaching a patch that prints this instead: > ls.str() xx : <active binding> Although a better behaviour would be to

Hi, I stumbled upon a surprising behavior when using an active binding as a loop index variable in R 4.0.0. In contrast, the behavior observed in R 3.6.1 is in line with my expectations. Consider the code below: makeActiveBinding("i", function(value) { if (missing(value)) { x } else { print("set") x <<- value } }, globalenv()) i <- 1 # output

A while ago Luke Tierney remarked that the warning associated with 'makeActiveBinding'-- "saved workspaces with active bindings may not work properly when loaded into older versions of R"-- should probably be removed in R-devel. It's still cropping up *sporadically* with R-alpha of 3/4/2004, but not every time I call 'makeActiveBinding'. So, two questions: (i) is it

I've noticed the following oddity where capture.output() prevents eval() from evaluating an expression in the specified environment. I'm not sure if it is an undocumented feature or a bug. It caused me many hours of troubleshooting. By posting it here, it might save someone else from doing the same exercise. Start by defining foo() which evaluates an expression locally in a given
