I am doing multiple imputation with Hmisc, and can't figure out how to replace the NA values with the imputed values. Here's a general ourline of the process: > set.seed(23) > library("mice") > library("Hmisc") > library("Design") > d <- read.table("DailyDataRaw_01.txt",header=T) > length(d);length(d[,1]) [1] 43 [1] 2666

rm(list = ls()) #borra todo lo anterior en memoria setwd("G:/Public/Documents/R/EPICALC/") #como se llama la data desde su path sanda<-read.csv("sandavid2.csv",header=TRUE, sep=",", dec=".") use(sanda) attach (sanda) library (MASS) label.cronbach <- label.var(p01, "¿Consume mucho pan? ") ####¿Hay alguna manera de nombrarlos

¿existe algún método en el cual no sea necesario hacer este trabajo y que aparezcan los nombres de las preguntas? label.cronbach <- label.var(p01, "¿Le agrada el programa que se le ha mostrado? ") label.cronbach <- label.var(p02, "¿Cree que ayuda en el aprendizaje?") label.cronbach <- label.var(p03, "¿Propicia el trabajo en el equipo?") label.cronbach

Hola, Todos estamos muy bien, gracias. Con respecto de tu consulta, creo que ofreces poca información para poder reproducir o intentar emular tu inquietud (aunque en este grupo de voluntarios hay gente muy hábil que seguramente podrá ayudarte mejor). Yo me pregunto, por ejemplo: ¿cómo son tus datos originalmente?¿los estás leyendo de otro programa?¿los tienes en un texto plano?¿podrías enviar

Dear alltogether, I experience very strange behavior of imputation of NA's with the NORM library. I use R 2.2.0, win32. The code is below and the same dataset was also tried with MICE and aregImpute() from HMISC _without_ any problem. The problem is as follows: (1) using the whole dataset results in very strange imputations - values far beyond the maximum of the respective column, >

Hello, I have written a small function ('JostD' based upon a recent molecular ecology paper) to calculate genetic distance between populations (columns in my data set). As I have it now I have to tell it which 2 columns to use (X, Y). I would like it to automatically calculate 'JostD' for all combinations of columns, perhaps returning a matrix of distances. Thanks for any help

Hello, attached patch (1.0-test29) adds LOGIN authentication mechanism. Tested with KMail and seems working. Please consider applying. Best regards. P.S.

Estimado José, Es la segunda vez que veo te pregunta en este Foro, la primera vez se te pidió mas detalles y luego se te dio una respuesta. El hecho que reiteres tu pregunta, sin detalles y sin mencionar que es lo que no funcionó con la respuesta anterior, me hace recordar algunas recomendaciones que leí en una excelente respuesta en http://stackoverflow.com/, que trato de adaptar a

Dear R-ophiles, I've found something very odd when I apply convolve to ever larger vectors. Here is an example below with vectors ranging from 2^11 to 2^17. There is a funny bump up at 2^12. Then it gets very slow at 2^16. > for( i in 11:20 )print( system.time(convolve(1:2^i,1:2^i,type="o"))) user system elapsed 0.002 0.000 0.002 user system elapsed 0.373

I was asked by my boss to do an analysis on a large data set, and I am trying to convince him to let me use R rather than SPSS. I think Sweave could make my life much much easier. To get me a little closer to this goal, I ran my analysis through R and SPSS and compared the resulting values. In all but one case, they were the same. Given the matrix [,1] [,2] [1,] 110 358 [2,] 71 312 [3,]

Dear R friends: Can someone help me with the following problem? Many thanks in advance. # Problem Description: # I want to write functions which take a (character) vector of dataframe names as input argument. # For example, I want to extract the number of observations from a number of dataframes. # I tried the following: nobs.fun <- function (dframe.vec) { nobs.vec <-

Hello, I'm trying to figure out how to find the index of the second occurrence of "/" in a string (which happens to represent a date) within a data frame column. I've used the following code successfully to find the first instance of "/". dframe <- data.frame(date=c("5/14/2011", "4/7/2011")) dframe$x1 <- regexpr("/", dframe[, 1])

Hi, I have a data frame with column names "1", "2", "3", ... and I'd like to extract a subset based on the values in the first column. None of the methods I tried worked (below). x <- subset(dframe, 1 = = "My Text") x <- subset(dframe, "1" = = "My Text") x <- subset(dframe, names(dframe)[1] = = "My Text") Q

I need to rsync 4 TB datafiles to remote server and clone to a new oracle database..I have about 40 drives that contains this 4 TB data. I would like to do rsync from a directory level by using --files-from=FILE option. But the problem is what will happen if the network connection fails the whole rsync will fail right. rsync -a srchost:/ / --files-from=dbf-list and dbf-list would contain this:

Hi all... First, thank you to Matt Chapman for pointing out why I could not connect to a non-domain participating machine. I needed to have a local account on that machine (it wasn't checking back with the domain controllers as I thought it would). I guess I'm going to have to start venturing out of the UNIX world and into the NT one. Scary :-) Either way, I now successfully am

Hi, I really feel I've looked everywhere, although I know this can't be a hard problem. I'd like to be able to call the graph below as a function, but I can't get the function to recognize variables beyond 'dframe'. I've read through many papers on writing functions in R, but I can't get this to work. data <- data.frame('date' = as.Date(rep(c(15101,
