recursively count the words occurrence in the text files
I just can't google for it:
I'm searching for a "bash" "one liner" (awk, perl, or anything) for this:
there are text files, in several directories:
mkdir one
mkdir two
mkdir three
echo "word1 word2 word3" > one/asf.txt
echo "word2 word4, word5" > one/asfcxv saf.txt
echo "word1. word2" > one/dsgsdg.txt

re ading tokens
Greetings,
I am not familiar with processing text in R. Can someone tell me how to
read each line of words as separate elements in a list?
FE, I would like to turn:
word1 word2 word3
word2 word4
into a list of length two with three character elements in the first list
and two elements in the second. I know that this should be easy, but I am a
little confused by the text functions.

How does findAssocs() calculate the correlation value ??
hi:
I want to know the math behind the "tm" package findAssocs().
I have found that someone had asked the question before, and have a good explanation by Rick.
?]http://r.789695.n4.nabble.com/findAssocs-td3845751.html?^
But I still don't understand how to calculate the correlation value between the two vectors.
For example:

Combining a greek letter and a newline on the same label
Hi,
I would like to add a two-lines label consisting of:
"Delta word1\n
word2"
(with Delta being the actual greek letter).
However, when I try "expression(paste(Delta,"word1\nword2"))", I obtain the
following display:
"word1\n
Delta word2".
Do you have any idea on how to obtain the desired display?
Thank you for your help!

Extending/Modifying QueryParser
Hi,
I''ve implemented synonym searching in my rails application but have
an idea I''d like to implement but can''t figure out how to do. The
idea is that I''d like to give the end user the choice on whether to
search for the synonym of a word or not. Preferably by extending the
query language to parse a construct similar to ''%word1'' and

sorting during xtabs? sorting by "individual" order?
Hey alltogether,
refacturing a package (before it will be released),

The second directory contains different files. It

Issues reshaping data
Hello All,
I'm having some trouble reshaping my data from wide to long format. I have
tried using both the reshape function and package. Although I haven't worked
much with the reshape function, I have found the reshape package useful and
intuitive for reshaping data from long to wide format. However, going the
other way has me stumped with this type of data. My data is set up, roughly,

NEED HELP : Association in single DTM
I have free text data in a single text document. I create a corpus, and
then a document term matrix out of it. I can create a word cloud too.
But when I do word association for the same, using "findAssocs(), it always
returns numeric(0).
EX : findAssocs(dtm, "king" ,000000000000000000000.1)

Word97 launches but still cannot save or load
Dear friends:
Thanks to Ekkehard, I found out how to launch Word97. I went to
the .wine/drive_c directory and then (using quotes around "Program Files"
and "Microsoft Office") I cd's to where Winword.exe was and then typed,
within this subdirectory: wine WINWORD.EXE. That launched Word97 at last.
But when I try to save a document, all I get is the first letter of the file

Can a variable name include '_' or '.' in portable R code
Hi,
It says in R-intro.pdf, "For portable R code (including that to be
used in R packages) only A?Za?z0?9 should be used." I'm an wondering
why '_' and '.' can be used in portable R code.
It very common that some variable name should be composed of two or
more English words. Can somebody let me know what is the widely
accepted practice to concatenate two English

NEED HELP : Association in single DTM
If you consider the definition of a DTM, and that findAssoc() computes associations between words as correlations across documents(!), you will realize that you can't what you want from a single document. Indeed, what kind of an "association" would you even be looking for?

In general, statistical methodology queries, which seems to be your

stats.stackexchange.com for statistical queries.

Similar words
Is there a way to get a list of similar words to the ones a user has
searched for?
So if they search for (in my case) transferaze which has no matches I
can get back an array like this [''transferase''] ?
I know I can just add ~ on the end to make it fuzzy, but what I''d like
is to be able to say "Sorry, no matches for ''transferaze''. Did you

range() for Date and POSIXct could respect `finite = TRUE`
Hi All,
I think there may be some possible confusion about what allowsInf would be

Consider a class "myclass", S3, for starters,
with

Then, what would

myclassthing[1] <- Inf
