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.
Thanks in

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 two
mkdir three
echo "word1 word2 word3" > one/asf.txt
echo "word2 word4, word5" > one/asfcxv saf.txt
echo "word1. word2" > one/dsgsdg.txt

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,

findAssocs()
I am trying to find the math behind the "tm" package findAssocs()
?findAssocs does not say anything besides "association" and "correlate"
Usually entering "findAssocs" at the CLI gives the code for a R
function, but in this case I obtain:
function (x, term, corlimit)
UseMethod("findAssocs", x)
<environment: namespace:tm>
Any ideas?

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

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

sorting during xtabs? sorting by "individual" order?
Hey alltogether,
refacturing a package (before it will be released),
I ran across the following problem.
I have two directories with different text files,
I want to read the first and construct a document-term
matrix from it (every term=word in a row, every file in
a column, occurrence frequencies form the values).
The second directory contains different files. It

Full text search improvements
FTS indexing is something I hear quite often nowadays. I?ve added some hacks to make it work better for some installations, but it?s about time to think about the whole design and how it could be improved for everyone in future. Here are some of my initial thoughts.
Currently Dovecot supports 3 full text search engines: Solr, CLucene and Dovecot Squat. CLucene plugin has various features built

Greek letter included in a character vector
Hello,
In the past I have used "expression" to include greek letters in axis labels,
but this time I need to include the greek letter as part of a legend. Basically,
I need to create the following vector to rename the levels of a factor:
c("Interferon-gamma", "IL-10", "IL-5"), where "gamma" obviously needs to be

plot greek letter in italic
Hi,
Could someone please let me know how to plot greek letters in italic.
text(0,14,expression(italic(rho)[italic(f)])) only plots the f in italic and
text(37,40,expression(italic(rho))) doesn't plot rho in italic.
I have checked demo(plotmath), ?plotmath, FAQ, and the archives
2004-2006 without finding the answer.
I'm using R 2.1.1. and Windows XP.
Thanks!

Greek letter
Hi everyone.
I'm trying to use small letter phi in a graph produced in R. However, the
small letter phi does not look as it should.
In fact, it looks like this:
http://r.789695.n4.nabble.com/file/n3963311/Untitled.png
instead of what is here http://en.wikipedia.org/wiki/Phi
Here's the code I use:
expression(phi [1])
Anyone has an idea?
With regards,

CairoPDF and greek letter spacing
I have a small problem with R graphics output. When I use the lattice
package and CairoPDF to generate publication quality graphs I often use
the expression to create an axis title that has microlitres or
micrometers as a unit. I use something like the following
'expression(paste("Length (", mu,"m )"))' as an argument to the xlabel
function. The command works but the mu

Combining greek letters with the contents of variables
Dear r-help list,
I am trying to combine a greek letter lambda with the contents of a variable v in the title of a plot. However, it seems that having v inside the expression() function causes it not to be evaluated, on the other hand having expression(lambda) inside something else like paste causes it to be evaluated to a string. Here is an example of what I want to do:
