Hi, It appears that there is no package for estimating log linear models (L. Goodman's family) for data in the form of frequency tables. Am I wrong?

Hello to all. My question is very simple... Let's say we have a data frame with three variables (columns): X, W and F. X is a numeric variable (e.g. like income) F is a factor (e.g. with 2 levels) and W is a case weight (data are from household sample but an individual was interviewed, weights are functions of number of persons in the house hold). I wanted to compute a means of X weighted

Hello everyone, I encountered the following confusing behavior of 'deparse' and 'substitute' while programming with S4 classes (see example below). It seems like the presence of '...' argument in the definition of the generic generates the problem. I have no clue why, can anyone explain that to me? Are there any "workarounds"? Thanks a lot for your time!

Dear useRs and wizaRds, I am currently developing a set of functions using S4 classes. On the way I encountered the problem exemplified with the code below. For some reason the 'validity' method does not seem to work, i.e. does not check for errors in the specification of the slots of the defined class. Any hints? My understanding of the whole S4 system was that validity checks are made

Hello dear useRs and wizaRds, I encountered the following problem using the hist() method for the 'times' classes from package 'chron'. You should be able to recreate it using the code: library(chron) # pasted from chron help file (?chron) dts <- dates(c("02/27/92", "02/27/92", "01/14/92", "02/28/92", "02/01/92")) class(dts)

Dear R-users, Recently I had to analyze a dataset from household survey. The sample design ensured, that each household in the population has the same probability of being sampled. However the data were gathered from only one adult individual in each household, who was randomly choosen by an interviewer (via "Kish grid"). To equalize the probabilities for each INDIVIDUAL a casewise

Hello dear useRs and wizaRds, I am currently developing a package that will enable to use administrative map of Poland in R plots. Among other things I wanted to include region names in proper Polish language so that they can be used in creating graphics etc. I am working on Windows and when I build the package it is complaining about non-ASCII characters R code files. I was wondering what would

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the

Andy, Take a look at Greenacre, Theory and Applications of Correspondence Analysis. He has many example of dealing with all sorts of data. Basically, the technique is relevant for 2-way tables -- MCA is an extenstion. It is not clear in your example whether CA is really appropriate -- you want to make an observation (if at all possible) fall in one cell, treating the others layers as

Hello, I just finished installing gluster on two machines in server mode in EC2. I have mounted it via fuse on one of the boxes. Here is my volume info: # gluster volume info Volume Name: fast Type: Stripe Status: Started Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: server1:/data2 Brick2: server2:/data All of this works great, and I can write files at a fairly high throughput.

Hello to all I've got a question concerning use of fonts while making plots in R. I wanted to know if it is possible for me to use polish letters in functions like text() title() etc. Looked up characters, which can be obtained via Hershey(), but there are none of them. I made plots using postscript(), pdf() or png() device to export them to MSWord or LaTeX. Windows ANSI CE #dec codes of

Dear sir, I would ask if there are in R some code to generate a random sample from a mvariate student distribution like that one wich generate the multivariate normal one i mean( rmvnorm(n, mu, sigma) Second question : if R can plot density 3Dcurve I don't mean de histogram but de hole density function(normal for example). I use a windows version of The R software Thank you in advance wiyh

A quick question. I am trying to understand how I could move the installed packages in my R 2.3 version to the newly installed R 2.5 version, without having to install all the packages again. I copied the files under the old library subdirectory to the new library subdirectory. But still the newer version is not recognizing the packages that were copied over. Thanks.

Hello, I am using Dotplot (from Frank Harrell's HMISC library) to make a graph of rates with confidence intervals but I get a 'black' background -- nice but not on a printed document: >Dotplot(group~Cbind(rate,lower,upper)|mortality,data=mort,ylab=' ') How do I change the background (and other) collors in Dotplot? Thanks for you help. Marwan Khawaja platform

Hello, Based on replies (which I'm gratefull for) I guess the only solution is to create a package, that will contain function to build lm()-like linear models, and allow weighting cases (as I described two days ago). This would also alow buliding those models for data in aggregated form without a need for using e.g. expand$grid(). Thank you again for replies.

I have the same question that Eusebio had: Is there a function similar to "sink" that redirect also R code to a file that is: sink("R001") x <- c(2,-6,-4,8,5,4,1,3,4,-9,0,1) A <- matrix(x, ncol=3) A A.prima <- t(A) A.prima dim(A) dim(A.prima) sink() create a file "R001" with contents: ------------------------------------------ [,1] [,2] [,3] [1,]

Hello, I get a nice looking barplot using the barplot2 function in the gregmisc package: body2 <- barplot2(hh3, beside = TRUE, col = c("mistyrose", "lightcyan"), .... cex.names = 1.0, plot.ci = TRUE, ci.l = cil, ci.u = ciu, plot.grid = TRUE) box() However, obviously I lose the collors when converting from ps to a pdf (outside of R)
