If one specifies new options in a package, using the options() function, where does/should one document these new options? E.g. suppose that I put the line options(melvin=42) in a file zzz.R in the R directory of the package source, where the package contains functions foo(), bar(), clyde(), and irving() which all query options("melvin") and take some action based on the value of

This may be an FAQ, but a (perfunctory) search failed to turn it up. Suppose I have a function foo(...){<something>} and I want to obtain, inside foo, the names of items comprising the ``...''. E.g. if I call foo(melvin,clyde,irving) I want to be able to loop through the ``...'' and successively obtain the text strings "melvin", "clyde", and

I am trying to build a function in a context where the environment concept would appear to be useful. But I'm a bit foggy about this concept and would appreciate some pointers and advice. Basically the function I'm building, say foo(x,t), is a function of two variables). Depending on the value of t, foo will return one of the values f1(x), f2(x), ..., fk(x), where each of f1, ..., fk is

I've just installed version 1.4.0 of R, and am experiencing a puzzling phenomenon with the library() function. I have .lib.loc set as follows: > .lib.loc [1] "/usr/local/lib/R/library" "/home/faculty/rolf/Rlib" If I invoke > library(melvin) I get the error message Error in library(melvin) : There is no package called `melvin' but if I invoke >

I gather from reading the back-issues of r-help that it should be possible (modulo a number of caveats) to read an excel (yuck!) file into R using RODBC. I have obtained and installed ODBC and the RODBC package, but cannot for the life of me figure out how to go about it. Can anyone give me a simple recipe? I have an excel file on cdrom, say: /mnt/cdrom/melvin.xls I have started R and loaded

This is just an idea for comment. Perl6, the upcoming version of Perl has separated out the runtime into a virtual machine called Parrot. There are already several small languages (one is C-like, one is Java-like and one is BASIC-like) that target Parrot and given the popularity of Perl its likely that others may attempt to target it too. If R could interface easily with Parrot then it might be

I've built R functions to ``effect'' a particular distribution, and would like to find out if that distribution is already ``known'' by an existing name. (I.e. suppose it were called the ``Melvin'' distribution --- I've built dmelvin, pmelvin, qmelvin, and rmelvin as it were, but I need a real name to substitute for melvin.) The distribution is really just a toy

I'm curious if any of the core R developers have considered the possibility of hosting R (v2?) on the parrot common runtime environment. Perl6 will generate byte-code for parrot, as will some future version of python. I can imagine both drawbacks and advantages. Some advantages would be fast byte-code execution and freely mixing perl, python and R modules. Anyone looked into this? Tim

Hi Everybody, I keep getting this error from log.smbd: find_name_on_subnet: on subnet 192.1.8.1 - name STORE 8<1d> NOT FOUND I'm wondering where it is getting the name 'STORE 8', when my hostname is 'store8' (no space in-between). Previously, I used 'store 8' as workgroup in smb.conf but I've already changed it other names. Do you have any idea what

Hi Lang, Thanks a lot for taking time to look into this. I will test the fix soon and let you know the results.

Just now I again had occasion to want nested describe lists in a documentation file. I found that the bug which I reported on 18 October, 2001 still persists. I checked on the bug report at the R web page, and found that the notes say ``Not a problem in R 1.4.0 (2001-12-08)''. Well, it's still a problem for me --- using R 1.4.1.

Hi Arnaud, Apologies for the delayed reply. Thank you for the excellent test case - it exposed a subtle bug in the colorability heuristic. This has been fixed in r153958. In case you are curious, the bug was as follows: the PBQP solver applies applies a simplification step to each matrix. When all elements of a matrix row or column are equal, the value for those elements is "pushed

Hi Lang, The assert is not triggered any longer on my testcases :) I however still get my wrong allocation in some non trivial cases : the pairing constraint is not fulfilled. I have tried to modify the 'ensure pairable' pass (the pass undoing some of the coalescer's work) to always insert register copies for instructions with the pairable constraint, instead of being smart and
