Hi: I am trying to cluster the rows of a text file with kmeans: I load the data as follows file1 <- read.csv("somefile.csv") and the file can be viewed having the following line of words > file1 1 word1 word3 word4 word1 2 word1 word4 word3 word1 3 word4 word2 word4 word3 4 word4 word2 word1 word3 5 word2 word2 word4 word2 file_as_matrix <- as.matrix(file1); Now, I want to apply some clustering algorithm such as kmeans to cluster the rows in the file to get the following output: Cluster1 word1 word3 word4 word1 word1 word4 word3 word1 Cl...

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 advance! -- View this message in context: http://old.nabble.com/reading-tokens...

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 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 [...

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, word3!" > two/sdgsd dsf.txt echo "word6" > two/ergd.txt echo "asdf, word2" > three/werdf.txt echo "wo...

...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.

...9;_' 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 words into a variable name? For example, shall I use "word1_word2" or "Word1Word2" or "word1.word2"?

...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: # Correlation word2 with word3 cor(c(0,1,1,1,1),c(0,0,1,1,1)) [1] 0.6123724 How does it caculate cor(c(0,1,1,1,1),c(0,0,1,1,1)) to get 0.6123724 ?

...ow 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 then have the word turned into a or list (i.e., word1|word2|word3|...). Currently, the query parser constantly calls SynonymTokenFilter to get synonyms for each token. Is there a way I can go about achieving this functionality? Here''s an overview of what I''ve done so far: My model classes in my rails app use acts_as_ferret with a ca...

...text, it's pretty useless to index it. Then again, we do want to index all kinds of IDs that someone might want to search. This could be a bit difficult to implement well. 8. Index attachments separately, so it would be possible to search only attachments. (Should "SEARCH BODY word1 BODY word2" return matches if word1 and word2 are in different attachments?) 9. Attachments can be translated to indexable UTF-8 text already with fts_decoder setting by doing it via a conversion script. This could also support Apache Tika server directly. 10. It should be configurable which fields are...

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
