R-alpha: apropos() available
Martin and I have `written' a function apropos() for finding all objects
with names matching pattern. I attach code and documentation. Perhaps
one could include it in the distribution proper.
We are not sure about returning the position in the search list along
with the matching names found. Martin thinks it should be on by
default, I think it should be off so that the functions does the

Apropos the day...
Since today is American Thanksgiving, I want to thank:
(a) R-core for all of their efforts to produce what is, IMHO,
the best statistical software around, not simply for the
convenience of doing more, better, quicker, but also
because it changes the landscape in the way one
thinks about data analysis. It's a fantastic playground
for a statistician and I enjoy using it

What happened to Ross Ihaka's proposal for a Common Lisp based R successor?
Is it conceivable that Julia could be ported to use R syntax in a way that
would allow the vastly larger numbers of R programmers to seamlessly
switch? Or equivalently, could an iteration of R itself do this?

A possible improvement to apropos
Hello all,
I've had the following apropos alternative in my ~/.Rprofile for some
time, and have found it more useful than the current version.
Basically, my version ignores case when searching.
If others find this useful, perhaps apropos could be suitably patched
(and I'd be willing to create such a patch).

Here is my version of apropos:

apropos changes in r-devel: intended feature or bug?
The old apropos started with:
if (!is.character(what))
what <- as.character(substitute(what))
The new one has:
if (character.only)
stopifnot(is.character(what))
else what <- as.character(substitute(what))
i.e., the check for is.character(what) is missing. This has the effect
that 'what' can no longer be a character string generated by a
function call

But you can easily fall back to R from within Julia; see

Sort output of apropos
A further improvement to apropos() would be to sort the output.
Currently, the output of apropos is in the order found on the search
list and this will rarely be useful to the user.
All that is needed is a sort(x) at the end of the function.

apropos and find
Hello,
I'm starting working myself in the use of R, reading M. J. Crawley, The
R Book. The problem I do encounter is concerning the commands apropos
and find:
> apropos(edit)
Fehler: is.character(what) is not TRUE
> find(edit)
Fehler: is.character(what) is not TRUE
I get the same error message typing anything else instead of "edit".
The command ?edit seems to work well.

Calling R (GNU R) functions from Common Lisp, how?
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 functions in CRAN are far richer
than Lisp-Stat currently has.
I want to know if there is

Possible (ab)use of lexical scoping in R ?
Dear list,
I wish to define a set of functions *auxilliary* to another set of
"main" ones, and I wonder if there is some "clever" way do do this using
lexical scoping. Looking for that in the list's archives did not get me
easily understood answers. Perusing MASS (1st, 2nd, 3rd and 4th
editions!) and "Programming S" wasn't of much help either...

Ross Ihaka's reflections on Common Lisp and R
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. I am not sure where to
post this for the R community but since it has to do with development I
thought or R-devel

Scheme in R
The initial authors of R said?, "...we implemented the language by
first writing an interpreter for a Scheme subset and then
progressively mutating it to resemble S." Further on in that article
they elaborated that their strategy was to create a parser that would
take expressions in S-like syntax and translate them to Scheme
S-expressions.
Does R still work that way? Can R be made to

Calling LISP programs in R
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 foreign library but this seems to

access to R parse tree for Lisp-style macros?
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 manually put into a function
yourself if you cared

Porting let* from Common LISP to R
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 visibility of preceding variables.".

I wanted to roll out my own lisp, and maybe use some library code from existing
lisps (think of loop or format). Adding an LLVM backend to an existing lisp
implementation is a nice idea, but currently not planned.
