Hi, just in the process of updating my packages for R v2.0.0 and I have not had time to followed the R v2.0.0 discussions so maybe my questions have already been answered. A concern I have is that when creating packages they should be backward compatible with R v1.9.x for a while until all users and computers has migrated to R v2.0.x. It is pretty straightforward to setup my packages so that

I am looking to do some text analysis using R and have run into some issues with some of the packages. Im not sure if its my goofy Vista OS or what but using R 2.8.1 i s relatively successful loading the text but the rJava package was messed up somehow: library(tm) > library(rJava) Error in if (!nchar(javahome)) stop("JAVA_HOME is not set and could not be determined from the

Hi, Gurus Thanks to your good helps, I have managed starting the use of a text mining package so called "tm" in R under the OS of Win XP. However, during running the tm package, I got another mine like memory problem. What is a the best way to solve this memory problem among increasing a physical RAM, or doing other recipes, etc? ############################### ###### my R

I am using code that previously worked to remove stopwords using package "tm". Even manually adding "the" to the list does not work to remove "the". This package has undergone extensive redevelopment with changes to the function syntax, so perhaps I am just missing something. Please see my simple example, output, and sessionInfo() below. Thanks!

Buenas tardes, grupo. Estoy tratando de hacer la comparación de dos archivos de una misma organización para encontrar las diferencias entre su informe del tema edl año 2005 y el del año 2013: Todos los comandos van bien, a exepción del último "colnames", como se ve en la siguiente secuencia: > pdf1<-"./PLAN de INSPECCIONES/05_seguridad_ciudadana.pdf" >

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

Hola a todos! Tengo algunos problemas con el tamaño de la matriz de términos que obtengo. Los comandos que utilizo son los siguientes: # carga librerias library(tm) library(wordcloud) library(Rstem) library(Snowball) # lee el documento UTF-8 y lo convierte a ASCII txt <-

Hello, I would like to know what can I do if I use strplit with a string and I want to use the middle left,I mean I have this: strsplit("bA531F16-rep","\\-") [[1]] [1] "bA531F16" "rep" I would like to work just with bA531F16 in another variable, what could I do?, Thank you --------------------------------- Sé un Mejor Amante

Cordial Saludo Actualmente estoy realizando una función para gráficar una nube de palabras el código que tengo es el siguiente: library(twitteR)library(tm)library(wordcloud)library(RXKCD)library(RColorBrewer) tweets=searchTwitter(''@afflorezr'', n=1500) generateCorpus= function(tweets,my.stopwords=c(),min.freq){ #Install the textmining library require(tm) require(wordcloud)

Hi I'm having a problem with model.frame, encapsulated in this example: y1 <- matrix(c(3,1,0,1,0,1,1,0,0,0,1,0,0,0,1,1,0,1,1,1), nrow = 5, byrow = TRUE) y1 <- as.data.frame(y1) rownames(y1) <- paste("site", 1:5, sep = "") colnames(y1) <- paste("spp", 1:4, sep = "") y1 model.frame(~ y1) Error in model.frame(formula, rownames,

Hi there, I got a piece of code for the Iris data which allows to display correlation coefficients for each Iris species in the lower panel (color coded). I would now like to add e.g. a "*" to show the significance of each correlation next to the correlation coefficient. Furthermore I would like to make a t.test between the species "setosa" and "versicolor" for

Hello fellow R people, I can not figure out a pretty way to use strplit with vectors Imagine that I got the following data from someone with ID's representing several factors ID data A1-B1-t1 0 A1-B1-t2 1 A1-B2-t1 5 A1-B2-t2 10 A1-B10-t1 0 A1-B10-t2 1 A1-B20-t1 5 A1-B20-t2 10 ... I would like to turn this dataframe to station substation time data A1 B1 t1 0 A1 B1 t2 1 A1 B2 t1 5

Firstly hi to everyone on the list, I am new to this list ans also R so please forgive the simplicity of my questions over the next few months. I have version R 1.9.1 and want to perform z-scoring for a benchmarking procedure. I have tried to install Henrik Bengtsson's R.classes bundle (http://www.maths.lth.se/help/R/R.classes). I have downloaded the .zip file and placed the relevant folders

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"

No es un problema de tm ni de SnowfallC ni de mcapply (por el path utilizas linux, en windows mcapply según el manual no va bien) No defines bien los objetos que pasas. Pasas doc.corpus en lugar de corpus ( o asignas a corpus en lugar de a doc.corpus) . Depura los programas cuando salga un error de objeto, como te pone en el Error que pasas . Temporalmente lo tienes arreglado en

Buenas noches grupo. Saludos cordiales. He seguido en la búsqueda de una forma que me permita realizar la comparación de dos documentos pertenecientes a los años 2005 y 2013, y que pueda representar finalmente con wordcloud y con una table en la que las columnas sean los años de cada informe "2005" y "2013", y las filas sean las palabras con la frecuencia de cada una de ellas

I am attempting to install the Hmisc, rreport and Design packages, but am not able to do so. I am running R v1.9.1 on Mac OS 10.3.5. I have tried installation using both the GUI version of R and also running R from sudo in a terminal session. In the terminal I receive the following error: * Installing *source* package 'Design' ... ** libs g77 -fno-common -g -O2 -c lrmfit.f -o

I am a relative R newbie and I am having trouble with reshape() on R V1.9.1 on Linux. The same code appears to be ok when run on R V2.2.0 on Windows and a V2.1 on Linux. Any help would be great as I need to stay on V1.9 for the immediate future... Thanks, Reid Hutchins df <- data.frame(state= rep(1:2, each=8), school=rep(1:2,each=4), class=rep(1:2,each=2),Values2Columns=rep(1:2,

Hola, La referencia (gracias por proporcionarla) que has incluido es bastante clara y se puede seguir. ¿Has podido sobre tus dos discursos utilizar la misma lógica? La forma de salir de dudas, para empezar, es que adjuntaras el código que estás empleando por ver si hay algún error evidente. Aunque la forma adecuada para que te podamos ayudar es con un ejemplo reproducible: código + datos.

Hi, I find this behavior unexpected: --8<---------------cut here---------------start------------->8--- > strsplit(c("a,b;c","d;e,f"),c(",",";")) [[1]] [1] "a" "b;c" [[2]] [1] "d" "e,f" --8<---------------cut here---------------end--------------->8--- I thought that it should be identical to this:
