I have been tinkering with mosaicplot() and friends as a way of learning R. As part of this, I've written a pair.table() method for mosaic matrices, and would like to extend mosaicplot to work with loglin and logln (MASS) objects. I'm using R 1.4.0 on Win 98. I've been trying to figure out the formula interface, and think there's a bug, but not sure how to find it, yet alone fix

Hi, Can someone set me straight as to how to write formulas in R to indicate: complete independence [A][B][C] joint independence [AB][C] conditional independence [AC][BC] nway interaction [AB][AC][BC] ? For example, if I have 4 factors: hair colour, eye colour, age, sex does > mosaicplot( frequency ~ hair + eye + age + sex) mean that the model fitted is of complete independence of

...eneral R mailing list. Sorry if anyone receives the double post. Hi, I have a dataset of animals receiving some eye treatments. There are 8 treatments, each animal's right and left eye was measured with some scores (ranging from 0 to 7) 4 times after treatment. So there are nesting groups eyes within animal. Dataset attached > dat<-read.table("dat.txt",sep='\t',header=T,row.names=1) > dat$id<-factor(dat$id) > str(dat) 'data.frame': 640 obs. of 5 variables: $ score: int 0 2 0 7 4 7 0 2 0 7 ... $ id : Factor w/ 80 levels "1","...

Dear R Users, I have a question based on my research. I am analyzing reader-based diagnostic data set. My study involves diabetic patients who were evaluated for treatable diabetic retinopathy based on the presence or absence of two pathologies in their eyes. Pathologies were identified using the clinical examination (Gold standard method). In addition it can be identified by taking digital images of patients? eyes and this method is cost effective. Finally two readers go over the images independently and patients are diagnosed as either positive or n...

Dear R-helpers, Suppose I have dataset like this below: data(HairEyeColor) dfHEC <- as.data.frame(as.table(HairEyeColor)) my.dfHEC <- data.frame(Hair=rep(dfHEC$Hair,dfHEC$Freq), Eye=rep(dfHEC$Eye,dfHEC$Freq), Sex=rep(dfHEC$Sex,dfHEC$Freq)) my.dfHEC my.dfHEC$Hair my.dfHEC$Eye my.dfHEC$Sex and I know all levels for Hair, Eye and Sex. In my case, I

I have a dataframe. Let's suppose that i have two columns. The first one contains height, the second one contains eye color that can be Green, Blue or Brown. I want to calculate the aritmetic mean of the height only for those people who have Blue eyes. How can I do it?

Hi! Some time ago, I replaced calls to library() with calls to requireNamespace() in my package logmult, in order to follow the new CRAN policies. But I just noticed it broke jackknife/bootstrap using several workers via package parallel. The reason is that I'm running model replicates on the workers, and the formula includes non-standard terms like Mult() which are provided by gnm. If gnm

Hi the manpage for persp() has a wonderful section where a the trans3d () function is used with points() and lines() to add red dots and a green sinusoid to the Mexican hat surface. Does anyone have a way to tell what distance a point is from the eye/ camera? Take the following line: lines (trans3d(x, y=10, z= 6 + sin(x), pm = res), col = 3) Is there a function like trans3d() that returns

The rules for conformability of objects required for various operators remain a mystery as do some related problems like the rules for recycling in creating arrays etc. Would someone be able to direct me to where such rules are stated? In a related vein, there are all manner of operations that are readily coded in Gauss or in MATA that fail, often mysteriously, in R. Are there some

Are there any plans to integrate Virtual Earth''s Bird''s Eye view to mapstraction? I tried an "integration hack" but then found out that there are too many issues involved (check whether birds eye is available for the current map area, disabling zoom controls,...). Has anyone else tried it? Franz

Hi, I tried to encode a WAV file to FLAC. But then I get a strange message: 99% complete.

...f I get the analysis right for one of them, I've got them all. For simplicity, let us call any measurement we may be interested as "response". The study design is an unbalanced latin square, with 5 periods, 5 treatments and 6 subjects. Each subject has two measurements: left and right eyes. The model is as follows, with ":" denoting interaction... Fixed Effects = (Subject + Period + Dose):Eye Random Effects = Subject:Period + Subject:Period:Eye My main question is how to make this happen in R. I know that "aov" is not suitable. If you need any more information,...

I've got a 20 slide Powerpoint set up against the expected day someone says "Mitch, could you talk for a short while to the residents on how to use statistics?" It looks good at this end, but I'd love to get at least one more pair of eyes on it. Any volunteers? -- Due to the recession, requests for instant gratification will be deferred until arrears in scheduled gratification have been satisfied.

Has anyone already worked out the files involved in changing from the rather pedestrian screensaver to some more pleasing eye candy like Fedora Core 5 uses? thnx/ldv

I am using R to teach, and here are a couple of things that I thought would work didn't work. 1. I noticed the utility data(***,package=***) recently and like it very much, but unless I type in the whole word "package" I'll get an error in 1.4.0. For example, data(cats,package=MASS) works fine but data(cats,pac=MASS) doesn't. 2. drop1 doesn't seem to be as smart as

I have an application where I have a function to calculate results for a 2-way table or matrix, which returns a matrix with one less row and column. To keep this short, the function below captures the structure: fun2way <- function(f){ if (!length(dim(f)) ==2) stop("only for 2-way arrays") R <- dim(f)[1] C <- dim(f)[2] f[1:(R-1), 1:(C-1)] } Now, I want to
