Hi,
I am very happy. My problems are solved without one little thing:

AGREP
Hi all, I have two questions
1 - I have the version 1.4.1 of R, and it doesn't have the 'agrep'
function in the base library. Is there a way to make this funcion
avaliable in R 1.4.1? I mean, how to 'copy' it from R 1.8.1 and 'paste'
it in R 1.4.1?
2 - The AGREP function doesn't give me the Levenshtein distance (edit
distance). Is there a function in R that does

fuzzy search
This may be offtopic to Rails, but what are people doing to find records
based on fuzzy string matches? For example, if you wanted to find a
Person with name "David Heinemeier Hansson" but searched using the
string "Dave Hansson".
Currently I am find_by_sql that calls the PostgreSQL function
"levenshtein(string1, string2)" which returns results with a score

Bug in agrep computing edit distance?
The documentation for agrep says it uses the Levenshtein edit distance,
but it seems to get this wrong in certain cases when there is a
combination of deletions and substitutions. For example:
> agrep("abcd", "abcxyz", max.distance=1)
[1] 1
That should've been a no-match. The edit distance between those strings
is 3 (1 substitution, 2 deletions), but agrep matches

GSoC 2012: Learning To Rank
Hello, guys!
How's it going?
I would like to offer you myself again to implement one of the ideas
during the GSoC 2012.
I want to take care of the "Learning To Rank" project, but I would
also be glad to pick the "QueryParser reimplementation", "Dynamic
Snippets", "Gmane Search improvements" or even "Replace socket code

Scheme extension language plugin.
I've put a scheme plugin in users/racarr/compiz-scheme on
gitweb.open-compositing.org.
Essentially it allows the user to define a startup file
(~/.compiz/startup.scm) and fill it with scheme code to do neat things
and extend Beryl.
On one hand it acts like a super powered state plugin, on the other it
lets you define useful behavior specific to what you do with your
Compiz and share these

crash while building index
Hi,
I''m trying to reindex a model (I''m using acts_as_ferret) after having
added (via metaprogramming) a large number of fields (several hundred)
to the index.
It keeps crashing when trying to rebuild the index (the crash log is
below, from ferret_server.out) but it only seems to crash on Linux
(Ubuntu server 7.04, x86-64) whereas it''s fine on my OS X laptop

[LLVMdev] Spell Correction Efficiency
Hello Doug,
*putting llvmdev in copy since they are concerned too*
I've finally got around to finish a working implementation of the typical
Levenshtein Distance with the diagonal optimization.
I've tested it against the original llvm implementation and checked it on a
set of ~18k by randomly generating a variation of each word and checking
that both implementations would return the

bug en funcion 'agrep'
Estimados R-users:
Estoy intentando usar la función 'agrep' para hacer búsquedas en
cadenas de texto. El parámetro max.distance permite controlar la
medida de aproximación de búsqueda de la función de Levenshtein. No
obstante, cuando hago búsquedas específicas no obtengo siempre el
resultado deseado y no se si es un bug o que no entiendo bien el
algoritmo de búsqueda. Por

String search: Return "closest" match
Hi,
I have to match names where names can be recorded with errors or additions.
Now I am searching for a string search function which returns always the "closest" match. E.g. searching for "Washington" it should return only Washington but not Washington, D.C. But it also could be that the list contains only "Hamburg" but the record I am searching for is

text vector clustering
Hi,
I am a new user of R using R 2.8.1 in windows 2003. I have a csv file with
single column which contain the 30,000 students names. There were typo
errors while entering this student names. The actual list of names is <
1000. However we dont have that list for keyword search.
I am interested in grouping/cluster these names as those which are
similar letter to letter. Are there any

[LLVMdev] RegAllocSimple doesn't work
I tried both the most recent version of "simple" register allocation and
the one from last August, and neither seems to work correctly (they run,
but produce bad output). I used them to compile an old version of the
Unix "replace" utility (source code attached). Here's how I created the
executable:

Pattern names matching
Dear R magic guys.. I have two tables (actually will be dataframes), both
with names to be matched.
The names on the first dataframe are from a study with antenatal visits on
some health centers here. It happens that we need the delivery info. And
half and some thing else of the women decided to delivery some where else
our health units. We managed to get the names from some other places but now

[LLVMdev] request for help writing a register allocator

Are you using VirtRegMap::addSpillPoint and VirtRegMap::addRestorePoint ? If
not you may need to add calls to them to let the rewriter know where to
insert the loads/stores.

[LLVMdev] request for help writing a register allocator
I found the problem! My generated code is spilling correctly but is not
reloading at all. For example, if the original code has the equivalent of
this (where %1024 is a virtual reg):
%1024 = xxx
...
yyy = %1024
and I find no physical register for %1024, then I assign it to physical
register %edi and to a stackslot. That creates code like this:
%edi = xxx
store from %edi to the
