merging corpora and metadata
Greetings!
I loose all my metadata after concatenating corpora. This is an
example of what happens:

Loop sobre muchos data frames
Jorge
Gracias por el consejo. Aparentemente no lo estoy aplicando bien, pues el
objeto que obtengo no contiene lo que quiero.
Me explico, al ejecutar
txt <- vector('list', length = length(names)) #names el el vector donde ya
tenía almacenada la lista de txt's
for(i in seq_along(txt)){
txt[[i]] <- Corpus(VectorSource(names[i]))
}
obtengo el objeto txt:

Jorge, estimados colaboradores de R-help
Estuve tratando de utilizar un script para uno de los pasos en mi análisis,
que es transformar cada uno de los corpus en mi espacio de trabajo en un
objeto TermDocumentMatrix
Tengo un vector llamado bNames que lista todos los corpus que quiero pasar
a TDM, y construí los siguientes comandos:
tdm.n1 <- vector('list', length = length(bNames))

TM Package - Corpus function - Memory Allocation Problems
I'm using R 2.11.1 on Win XP (32-bit) with 3 GB of RAM. My data has
(only) 16.0 MB.
I want to create a VCorpus object using the Corpus function in the tm
package but I'm running into Memory allocation issues: "Error: cannot
allocate vector of size 372 Kb".
My data is stored in a csv file which I've imported with "read.csv" and

Loop sobre muchos data frames
Hola a todos!
Estoy en un proyecto de text mining y por razones de los recursos con que
cuento tuve que separar los archivos de texto de input del proyecto en
muchos archivos pequeños.
Luego de transformar cada uno de estos archivos en un corpus separado,
puedo aplicar limpieza sobre cada corpus, buscar n-gramas, construir cada
termDocumentMatrix y finalmente reunir todo en una sola TDM.

DocumentTermMatrix - text minig
Hi All,
I have a Data.frame that looks like that one below. I would like to do some text mining on it to possibly find some patterns between Opis, ACklasifikacija and Vodja. I looked over a tm package which loks promissing, more specifically DocumentTermMatrix or TermDocumentMatrix. But I can not figure out how to change my data from data.frame to Corpus or VCorpus.

Function failure in tm
HI all:
I have a customized source reader for the package tm (that Milan Bouchet-Vallat has been instrumental in producing).
I can get it to produce a corpus of class:
"VCorpus" "Corpus" "list"
class(mycorp[1]) returns
"VCorpus" "Corpus" "list"
and class(mycorp[[1]] returns
"PlainTextDocument"

Simple class with an automatic printing issue
I don't understand the following behavior for a simple S3 class. The
auto-printing at the command line
doesn't behave as I expect. I'm probably missing something, but it might be
a bug.

> structure(1, class = "testClass")

Buenas tardes grupo. Saludos cordiales Carlos J., muchas gracias por
tu orientación. Efectivamente, me había dado cuenta que la razón por
la que no se aplicaba colnames era porque no tenía columnas. La
cuestión es que no logro visualizar completamente/claramente en qué
parte del proceso de creación del corpus se puede hacer.
Sin embargo, siguiendo el ejemplo de

Creating a reference class object from a class definition in a package fails
Hi,
I'm trying to create a package that contains reference class
definitions from which users can create reference objects, but there
seems to be something awry.
My toy example creates an empty package via
package.skeleton('TestClass') to which I add the following R code:
TestClass <- setRefClass('TestClass',fields=c('name'))
Unfortunately my R console output

Reference Classes: Generalizing Reference Class Generator objects?
Is it possible to override the $new(...) in the reference class
generator? I have tried adding a "new" method to the methods of the
class, but that is obviously not correct. I have also tried adding it to
the class generator, but the class generator still uses the default
constructor.
As a simple example, this is the current interface:
TestClass <- setRefClass

slot assignment in S4 classes
Hi R friends,
I'm still studying S4 classes and I have a question about slot assignment. Why would I have to use a special setter method [example 2 below] if I can assign data to a slot directly when I call new() [example 1 below]?
## first way to do it (the idiosyncratic way?)
setClass(Class = "TestClass", representation = representation(myDf = "data.frame"))

Hi,
I want to ask for a small help for creating an instruction that calls
e member method of an object. I suppose that this is not a headache
but I am impatient in learning :) I would be very thankful if you can
show me an example snippet code that does this in LLVM. Below is
described my case.
Let's say I have a class TestClass
