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 echo "word6,

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

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?

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.

Preferably by extending the query language to parse a construct similar to ''%word1'' and

For example: # Correlation word2 with word3

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! Sebastien [[alternative HTML

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,

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

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.

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

Hi All, I think there may be some possible confusion about what allowsInf would be reporting (or maybe its just me :) ) if we did this. Consider a class "myclass", S3, for starters, with setMethod("allowsInf", "myclass", function(obj) FALSE) Then, what would myclassthing <- structure(1.5, class = "mything") myclassthing[1] <- Inf do. Assumely it

Sorry if this is the wrong forum to discuss Search::Xapian issues -- this just seems like the best place.. Anyways, I've been testing out using $db->add_database() when searching, and it seems like the docids I'm getting out of it are incorrect, almost as though they're "double" what they should be (numerically)... the docids that exist should be around 950,000 and

Hello, as I just spent a (too long) while searching for a way how to persistantly switch back the help display routines from chm to text, here a small documentation how to do that with the windows version of R.
