Hi Lisp users, I'm a user of both Common Lisp and R (GNU R). I found R has a rich collection of statistical and numerical computation functions, while it is not as extensible as Lisp (Common Lisp). I considered Lisp-Stat but its only implementation is not in the usuall Common Lisp, and the available f...

I have written some programs in Common Lisp and I have been using SAS to pipe those programs to my lisp compiler in batch mode by using the %xlog and %xlst SAS commands. I wonder if there is in R a similar way to pipe commands to LISP so that all my work would be concentrated in R even when I have to call a LISP program? I have looked at the...

I've read in many places that R semantics are based on Scheme semantics. As a long-time Lisp user and implementor, I've tried to make this more precise, and this is what I've found so far. I've excluded trivial things that aren't basic semantic issues: support for arbitrary-precision integers; subscripting; general style; etc. I would appreciate corrections or additions fr...

I came across a quite interesting post from Ross Ihaka, thought would be good to share it and get the opinion of folks around here.

In porting some Common LISP code to R, I am trying to found out whether special care must be taken for the let* function. In Common LISP, "the let* block is like let except it is guaranteed to evaluate the initialization of its local variables in sequentially nested scopes, i.e. it provides an order to the binding and v...

R folks, I'm curious about possible support for Lisp-style macros in R. I'm aware of the "defmacro" support for S-Plus and R discussed here: http://www.biostat.wustl.edu/archives/html/s-news/2002-10/msg00064.html but that's really just a syntactic short-cut to the run-time use of substitute() and eval(), which you could manual...

Dear R-devel, There is a new feature in R-devel, which explicitly refers to LISP @ operator for splicing. > The backquote function bquote() has a new argument splice to enable splicing a computed list of values into an expression, like ,@ in LISP's backquote. Although the most upvoted SO question asking for exactly LISP's @ functionality in R doesn't seems to b...

I mainly program in Common Lisp and use R for statistical analysis. While in R I miss the power and ease of use of Lisp, especially its many primitives such as find, member, cond, and (perhaps a bridge too far) loop. Has anyone created a package that includes R analogs to a subset of Lisp functions? Chris Elsaesser, PhD...

John Fox (see below) raises important questions for the Lisp-stat community (and perhaps the R community) to consider. This message thread was not cross-posted to r-devel@lists.r-project.org, so I do so now. I have never been an active or particularly adept Lisp-stat programmer. But I have worked on or used several projects for which Lisp-stat seemed the...

Hi everyone! I'm developing a Libvirt bindings for Common Lisp. The project is called "Lispvirt". I created this project because I was doing a project in Lisp to manage Virtual Machines. So, I needed to implement some code using C and set up Lisp to access those methods in C. This project was becoming a mess. The better scenario is using only Lisp. T...

I wanted to roll out my own lisp, and maybe use some library code from existing lisps (think of loop or format).

Hi Jan, In the lisp code you provide the operators are parsed as simple symbols in a pairlist. In the R snippet, they are parsed as left-associative binary operators of equal precedence. If you unquote a call in the right-hand side, you're artificially bypassing the left-associativity of these operators. To achie...

Thanks! I am trying to use it in R. (Actually, I try to give my students experiences with different kinds of files and I was wondering if there were tools available for such kinds of files. I don't know Lisp so I do not actually know what the lines towards the bottom of the file mean.( Many thanks for your response!

Hi, if you run a server in your Emacs session you can use emacsclient to send a lisp call to the server. There's an example here: https://emacs.stackexchange.com/questions/54156/how-can-i-query-emacs-from-a-separate-process/54161#54161 Regards, Martin Gregory On 11/10/23 11:18, Duncan Murdoch wrote: > I'm not an Emacs user, but the ESS-help mailing list (see > ess...

Hi, I'm using R in Emacs and I'm interested in programatically knowing the details of all opened buffers; details such a buffer name, size, mode, and possibly associated filename. I've been able to write such a function in Emacs Lisp, but now I'd like to be able to call that function from R, or if that's not possible then calling it from C would be fine. Does anyone know if this is possible? And if so, could you perhaps direct me towards an existing R package or program that calls an Emacs Lisp function from R that I c...

Hi! I've made great progress in my R programming, but I am again stuck on a beginner's problem. I would like to start R with a command line that loads a file, and if possible, executes a function. Can anyone give me an example of how to do this? For example, in lisp, I would say: $ lisp -load toto.lisp -eval '(do-something $PORT)' to load the file "toto.lisp", then evaluate the expression with the shell envt variable bound properly. I'd like to do this in R, but can't figure it out! Thanks, GF. [[alternative HTML version deleted...

I'm trying to do a little system hacking on CMU Lisp. Currently CMU Lisp has a minimum of two files needed to execute. One is a program usually called "lisp" that the OS runs, which basically a loader for the other file, a lisp.core file that contains the actual lisp system. People have been asking for a way to make a "lisp executab...
