Buenos días No sé qué es lo que estoy haciendo mal al aplicar la función recode. Escribo: personas_LR2 <-recode(personas_LR$edad, '0:15="Menores de 16 años"; 16:44="Entre 16 y 44 años"; 45:64="Entre 45 y 64 años";>=65"65 y más años";', as.factor.result=TRUE) y me da el siguiente error: Error en parse(text = strsplit(term,

Hi, A little question. I''ve written a method that uses PDF::Writer to generate a PDF document with some images and text. This is the code on my controller: def pdf gen_pdf redirect_to("#{@request.relative_url_root}/pdf/cupones.pdf") end private def gen_pdf pdf = PDF::Writer.new(:paper => "A4") pdf.margins_cm(0) pdf.start_columns(2, 0) pdf.select_font

Hi, I have a website in production wich uses a lot of date and time calculations to show specific information. The timezone of my hosting service (Dreamhost) is PDT, and the timezone of my potential clients is CEST. There are 9 hours of difference between them. Is there an environment variable that I could adjust in my rails application, so all date/time values be set to CEST timezone? Thanks.

Hello I have the following data frame which I read from an EXCEL file, and when i try to call one of its columns with a space in their names I am not being able to. For example if I do EURODOLLAR$ED1.Comdty Date I obtain the following error: Error: inesperado símbolo en "EURODOLLAR$ED1.Comdty Date" I have also tried using . or _ instead of the space and have obtained no succes. How do I

Hi, I'm trying to make a model in order to know wich factors got?s influence in the intensity of a infection, but just in the individuals who's got this infection. In my data I've got a variable called "prevalence" with 2 levels: 1.- Infected individual 0.- Non infected So what i'm trying to do is a subset in a model like this,

Hi, I have some problems with an application where I''m using custom accessors to do currency conversions. In my model, I have a price attribute in the database that stores the value in cents, to avoid future problems with float arithmetic and round. But at the views, I would like to show the price in euros, with decimal for the cents. So I defined a new attribute called price_in_euros,

En general lo que yo uso en esos casos es as.numeric(as.character(X)) No se los términos correctos pero los factores aunque se muestren con los nombres de las diferentes clases, internamente son clases separadas que se nombran como enteros por ejemplo del 1 al n de clases. Cuando usas directamente as.nuemric sobre un factor, este toma los numeros de las clases y no el valor de clase. Fijate en

That's one of the purposes of the namespace. See Prof. Tierney's article in the R Newsletter, or the slides of his keynote lecture at the useR! 2004 conference. It's also explained in the `Writing R Extensions' manual. Basically you only export functions that the users should see. The manual also explains how to not document functions that aren't intended to be called by

Hello list. Maybe this is a simple question but I can't find the answer anywhere. With lm I use the parameter y=TRUE to have the response returned in $y. Of course, namely because of NA's in the data frame, this might not include all the values in the original column. For example: > data(airquality) > length(airquality$Day) [1] 153 > my.lm <- lm(Day~.,data=airquality,y=TRUE)

Tranquilo que no te han hackeado tu "R"... Simplemente que al importar tu CSV, no has indicado que los decimales son las ",". Y ese campo lo importa como un character (un string). Y cuando lo conviertes a numeric, el resultado es un tanto impredecible. Si utilizas read.table para importar, simplemente incluye el parámetro "dec" de esta forma "read.table(..... ,

Muchas gracias, Fernando y Javier. > pami$PP <- as.numeric(as.character(pami$PP)) Warning message: NAs introduced by coercion Y entonces los datos que antes convertía en labels(pami$PP) (v.g. 753,2256 a 61343 o 62,7688 ? a 17390, que me pa eran enteros del 1 al n de clases como decía Fernando), los convertía en NA.- Luego de probar también con read.table, pasé a: > pami <-

Estimados compañeros me tiene loco un problema de codificación que no logro resolver. Importo un fichero cuyo nombre tiene acento. Pongamos por ejemplo "Adrián.doc". Escribo el siguiente comando: mdoc<-list.files(path = dest,pattern = "*.doc", full.names = TRUE) Entonces mdoc, además del path, se me presenta como: "Adria´n.doc" Aunque le quite la tilde con:
