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))

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: > class(txt) [1]

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. Pero

Hello, I would like to set up some automatic reporting using R. For this purpose, I need to include the output of "print" commands into the graphics produced by some "plot" commands. 1. Is there an easy way to do this? 2. Is it possible to redirect "print" into a string? (except redirecting into a file and than scanning back?) 3. What is the best way to get

Please, we do need complete reproduction instructions (and not speculation) as the FAQ asks. 1) How exactly did you read the file in? 2) 'longer' than what? 3) What line ending is this? I've just tried loading a 1000-line 50kb file using the 'Open Script' menu item, and it worked with CRLF, LF or CR line endings. Some guesses are that there are control characters in the

Hello, I have a data frame and want to do the following. Do a regression of one variable versus another: fit <- lm(a ~ b) Then I would like to plot the residuals of this fit versus a third variable: bwplot(residuals(fit) ~ group) This fails, if a or b contain NAs, because the data in the residuals() - vector are not aligned anymore to the data in the original data frame. Is there a

Dear all, I am planning to use nlme library for analysis of experiments in semiconductor industry. Currently I am using "lm" but plan to move to "lme" to handle within wafer / wafer-to-wafer and lot-to-lot variation correctly. So far everything is working well, but I have a fundamentel question: NLME offers "maximum likelihood" and "restricted maximum

Dear all, I have the following problem: - I have written a program in R which runs out of physical memory on my MacBook Pro with 1.5 GB RAM - The memory usage is much higher then I would expect from the actual data in my global environment - When I save the workspace, quit R, restart R and load the workspace again, memory usage is much less then before (~50 MB instead of ~1.5

Hi, suppose I do: b <- matrix(1:9,3,3) bname <- "b" now dim(b) returns [1] 3 3 and dim(bname) returns NULL is there a function to pass bname to such that dim returns the dimensions of b? like dim(somefunc(bname)) returns [1] 3 3 does 'somefunc' exist? daver +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |David Richmond It

Hello. These patches add a new mode of operation for the sftp server. It is located between the ordinary, unrestricted mode and read-only mode. It allows you to add files to the server, but only if these files do not exist on the server before. Changes to existing files - are prohibited. Please review them, maybe these patches will be useful not only to me. Thank you. -------------- next part

I have Postfix/Dovecot/postfixadmin/MySQL with several virtual mailbox domains one of the domains is like aname.com.au, the user also now has aname.com, and, would like to 'mirror' most of the addresses to be user at aname.com, THOUGH, some are to remain as user2 at aname.com.au so, both user at aname.com as well as user at aname.com.au should be one user the users retrive emails as

Hi, I thought that I would attempt a quick little patch that will make btrfsck into a No-op when called as fsck.btrfsck. The reasoning is that the FAQ states that it is recommended and safe to do so, and the current 12.04 version of Ubuntu just symlinks fsck.btrfsck to btrfsck instead of /bin/true. PS - Apologies if I mess this git send-email up! Dan McGrath (1): btrfs-progs: No-op when

While SVCB/HTTPS provides a better solution for the browsing use case, I see other use cases where ALIAS/ANAME would be ideal, notably in apex RRs. So while fostering SVCB/HTTPS deployment is a good thing, I wouldn?t mind name server software implementing ALIAS. Including NSD, but I reckon it?s much more challenging to do due to NSD architecture than it was to implement it in PowerDNS. But if

In a function, say foo.glm for glm objects I want to use the name of the object as a label for some output, but *only* if a glm object was passed as an argument, not a call to glm() producing that object. How can I distinguish these two cases? For example, I can use the following to get the name of the argument: foo.glm <- function(object) { oname <- as.character(sys.call())[2]

Hello, All :) Regarding to incoming caller ID on PSTN line, which one is best supported by asterisk: is it FSK ETSI or FSK US? I bought some caller ID converter hardware (convert DTMF to FSK and vice versa) but still asterisk can not detect it. The converter has a switch FSK ETSI or FSK US This is what I put in /etc/asterisk/chan_dahdi.conf ... cidsignalling=bell cidstart=ring ... If after

Hi Christof! AFAIK, PowerDNS is the only open source name server that supports ALIAS. There was an idea to standardize ALIAS as "ANAME" (https://datatracker.ietf.org/doc/draft-ietf-dnsop-aname/), but the idea was dropped in favor of SVCB/HTTPS record https://datatracker.ietf.org/doc/rfc9460/. So now we have to wait until all Browser vendors implement SVCB/HTTPS. Regards Klaus PS: If

smbclient (and smbtar) in version 2.2.7a (and prior) has problems with large files (> 4GB). The following patch (against 2.2.7a) fixes all known problems with this.

Hello, I have a nasty loop that I have to do 11877 times. The only thing that slows it down really is this merge: xx1 = merge(dt,ua_rd,by.x=1,by.y= 'rt_date',all.x=T) Any ideas on how to speed it up? The output can't change materially (it works), but I'd like it to go faster. I'm looking at getting around the loop (not shown), but I'm trying to speed up the merge first.
