Re: Ayuda Manolo, si no estoy mal tu tarea se soluciona con el uso de las funciones melt y cast del package reshape o en su defecto la versión mas nueva reshape2. ------------------------------ > > Message: 4 > Date: Tue, 30 Jul 2013 15:56:03 -0500 > From: Manuel Máquez <manuelmx11@gmail.com> > To: R-help-es@r-project.org > Subject: [R-es] Ayuda > Message-ID: >

xyplot doesn't seem to want to label my x-axis with dates but instead puts the day-number for each date. begdate is the number of days since January 1, 1960 and was initially created by library(date) ... polls$begdate<-mdy.date(begmm,begdd,begyy) I create a new dataframe (pollstack) which includes begdate. In the process begdate seems to lose its date attribute so I redo it as: >

Deal list, I have a data frame (birth) with mixed variables (numeric and alphanumeric). One variable "t1stvisit" was originally coded as numeric with values 1,2, and 3. After attaching the data frame, this is what I see when I use str(t1stvisit) $ t1stvisit: int 1 1 1 1 1 1 1 1 2 2 ... This is as expected. I then convert t1stvisit to a factor and to avoid creating a second

Hi, Recently added to doc/NEWS.Rd: 'R CMD check' now gives a warning rather than a note if it finds inefficiently compressed datasets. With 'bzip2' and 'xz' compression having been available since R 2.10.0, there is no excuse for not using them. Why isn't a note enough for this? Generally speaking, warnings are for things that are dangerous, or unsafe,

I have a file, each column of which is a separate year, and each row of each column is mean precipitation for that month. Looks like this (except it goes back to 1964). month X2000 X2001 X2002 X2003 X2004 X2005 X2006 X2007 X2008 X2009 1 1.600 1.010 4.320 2.110 0.925 3.275 3.460 0.675 1.315 2.920 2 2.960 3.905 3.230 2.380 2.720 1.880 2.430 1.380

Buenos días No sé qué función tengo que utilizar para cortar una variable cadena. Veamos a ver, teno la variable MUNICIPIO que recoge la siguiente información: 26001-Ábalos y necesito crear la variable COD_MUNICIPIO cuyo valor ha de ser 26001.

Hola, ¿qué tal? Tengo el siguiente problema. Me llegan (simplificando) cadenas del tipo 1,2,"algo"; 3,"cosa"; 4,2,3,7; y tengo que partirlas por el caracter ";" para meterlas en una lista. Lo hago con strsplit y no tengo problemas... ... hasta que recibo cadenas como 1,2,"algo;todo"; 3,"cosa"; 4,2,3,7; en las que existen puntos y coma

Hola a todos Esta es mi primera pregunta en el grupo, y es sencilla pero me tiene atascado. Estoy tratando de cortar mi mapa de (poner limites en UTM) en un lugar definido como mi area de estudio (en este caso el sur de chile). Pero creo no estar usando bien la función CRS ponendo bien los limites requeridos. > study_area <- readRDS("CHL_adm0.rds") > study_area_UTM <-

Hi, We upgraded from rsync 2.6.8 to 3.0.6, and ran into a problem with P (protect) rules coming in from filter files. The rule works if given on command line, but if given via . (merge), it no longer works. The effect is that files are not sent to the destination any more. I verified the problem still exists in 3.0.9pre2. I don't think this is bug 8309

Hi, I'm struggling to figure out the way to change the name of a column from within a loop. The problem is I can't refer to the object by its actual variable name, since that will change each time through the loop. My xts object is A. > head(A) A.Open A.High A.Low A.Close A.Volume A.Adjusted A.Adjusted.1 2007-01-03 34.99 35.48 34.05 34.30 2574600 34.30

I have written a few different summary functions. I want to calculate the statistics by groups and I am having trouble getting the output as a dataframe. I have attached one example with a small dataset that calculates summary stats and percentiles, I have others that calculate upper confidence limits etc. I would like the output to be converted to a dataframe with one of the columns as the

Hola, Estoy intentando averiguar cómo contar el número de categorías situadas después de ciertos valores. Por ejemplo, en el siguiente vector: x <- c(3, "A", "B", 5, "A", 4, 5, "A", "A", 3) el resultado que quisiera obtener es: Valor -> Resultado 3 -> 1 A y 1 B 4 -> 0 A y 0 B 5 -> 3 A y 0 B ¿Alguien tiene alguna

Hola a tod@s, Me han mandado una base de datos y al abrirla me he encontrado con la fecha y la hora en el siguiente formato: FECHA HORA 20121007 1206 20110622 1854 20110623 054 He conseguido que la Fecha me quedara en el formato dd/mm/aaaa mediante el script db[, "FECHA"] <- as.Date(as.character(db[,

The data set consists of two sets of matrices, as labelled by the columns, T's and C's. > xy x T1 T2 T3 T4 T5 C1 C2 C3 C4 C5 [1,] 50 0.00 0.00 33.75 0.00 0.00 0.00 36.76 0.00 35.26 0.00 [2,] 13 34.41 0.00 0.00 36.64 32.86 34.11 35.80 37.74 0.00 0.00 [3,] 14 35.85 0.00 33.88 36.68 34.88 34.58 0.00 32.75 37.45 0.00 [4,] 33 34.56

I write a function to get the frequency and prop of a variable. freq<-function(x,digits=3) {naa<-is.na(x) nas<-sum(naa) if (any(naa)) x<-x[!naa] n<-length(x) ta<-table(x) prop<-prop.table(ta)*100 res<-rbind(ta,prop) rownames(res)<-c("Freq","Prop") cat("Missing value(s) are",nas,".\n") cat("Valid case(s)

Hola, M. Luz. Hay infinidad de motivos por los que se te puede cortar la lectura de un archivo de datos, pero los más habituales son encontrar un "#" o unas "" en los registros, o una línea toda en blanco. Lo primero yo creo que es dejar el archivo en texto plano (lo que te recomendaba Carlos de usar el original, no el docx), y buscar esos caracteres con un editor de texto

También si nos envías el .rel nos ayudaría a ver qué pasa... Saludos, Carlos Ortega.

# head -1 /etc/centos-release CentOS release 6.5 (Final) Anyone using exim with MySQL support from epel without compiling direct from sources?

I have been having the same problem as poster Hodgess, below. It appears that her question was never answered, so I would like to share a solution with the community. The problem is the (apparent?) inability to produce moving range process behavior (a.k.a. "control") charts with individuals data in the package "qcc" (v. 2.0). I have also struggled with the same limitation in
