Hi Kynn, Thanks for expanding. I wrote a function like yours when I first started using R. It's basically the same up to your "new.env()" line, I don't do anything with environmentns. I just called my function "mysource" and it's essentially a "source with path"....

...ngth(x) [1] 2 I just could NOT believe my eyes! Am I going crazy??? What I'm trying to do is so simple and straightforward: I want to be able to append NULL to a list, and, after the appending, have the last element of the list be NULL. Is that so unreasonable? How can it be done? TIA! Kynn [[alternative HTML version deleted]]

...sed to mean here). What I'd like to do is print out SEXP's the way that the R interactive interpreter would display them if one evaluated them on the command line, but to do this from within gdb, or at least via a PRINT function called directly within the C code. Is this possible? TIA! Kynn [[alternative HTML version deleted]]

I'm looking for a way to approximate the "zero-overhead" model of code reuse available in languages like Python, Perl, etc. I've described this idea in more detail, and the motivation for this question in an earlier post to R-help (https://stat.ethz.ch/pipermail/r-help/2016-September/442174.html). (One of the responses I got advised that I post my question here instead.) The

Let me preface my question by stressing that I am much less interested in the answer than in learning a way I could have *found the answer myself*. (As helpful as the participants in this list are, I have far too many R-related questions to resolve by posting here, and as I've written before, in my experience the R documentation has not been very helpful, but I remain hopeful that I may have

Is there a *fast* converter between JSON and R? I'm aware of the rjson package, but it is implemented in R, and it is too slow for my purposes. TIA! kynn [[alternative HTML version deleted]]

...her* RJSONIO *or* rjson? (I.e. both are not required.) Second, what's the best-practice R idiom for such conditional loading? I.e. I'm looking for R's equivalent of Python's >>> try: ... import json ... except ImportError: ... import simplejson as json Thanks! kynn [[alternative HTML version deleted]]

Hi! I'm new to R programming, though I've been programming in other languages for years. One thing I find most frustrating about R is how difficult it is to use Google (or any other search tool) to look for answers to my R-related questions. With languages with even slightly more distinctive names like Perl, Java, Python, Matlab, OCaml, etc., usually including the name of the language

...me time, but I can't find the constructors for such objects (here I'm using the term "constructor" loosely). I'm even further from finding the C equivalent of "my.list[[ length(my.list) + 1 ]] <- new.thing". Can someone point me in the right direction? Thanks! Kynn

Hi Kynn, Do you mind defining the term "zero-overhead model of code reuse"? I think I understand what you're getting at, but not sure. Thank you, Frederick On Sun, Oct 02, 2016 at 01:29:52PM -0400, Kynn Jones wrote: > I'm looking for a way to approximate the "zero-overhead&qu...

I was surprised to see that there is a ScalarInteger function in Rinlinedfuns.h, but nothing like ScalarLong. How can one create an R-integer from a C long? TIA! kynn [[alternative HTML version deleted]]

Suppose function foo calls function bar. Is there any way in which bar can find out the name of the function that called it, "foo"? There are two generalization to this question that interest me. First, can this query go farther up the call stack? I.e. if bar now calls baz, can baz find out the name of the function that called the function that called it, i.e. "foo"?

Hi. I'm pretty new to R, but I've been programming in other languages for some time. I have a couple of questions regarding programming with function objects. 1. Is there a way for a function to refer generically to all its actual arguments as a list? I'm thinking of something like the @_ array in Perl or the arguments variable in JavaScript. (By "actual" I mean the ones

...at this initialization should be. If someone could point me in the right direction I'd appreciate it. Also, where is the documentation for the call_R function? It is mentioned several times in the Writing R Extensions document, but I have not been able to find the documentation for it. TIA! Kynn [[alternative HTML version deleted]]
