mosaicplot(formula, data)--- bugged?
...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 it. It seems to only work with independence models: > data(HairEyeColor) > mosaicplot(~ Hair + Eye + Sex, data=HairEyeColor) > mosaicplot(~ Hair * Eye + Sex, data=HairEyeColor) Error in aperm(a, perm, resize) : `perm' is of wrong length here's a traceback: > debug(mosaicplot) > mosaicplot(~Hair + Eye + Sex + Hair:Eye, data=HairEyeColor) debug...

formula (joint, conditional independence, etc.) - mosaicplots
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 all factors [hair][eye][age][sex]? So does > mosaicplot(frequency ~ hair + eye) mean that the model is of conditional independence [hairAgeSex][eyeAgeSex]...

lmer() vs. lme() gave different variance component estimates
Hi, I asked this on mixed model mailing list, but that list is not very active, so I'd like to try the general 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...

how to write crossed and nested random effects in a model
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...

how to make automatically each level from data.frame to vector
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...

Mean Help
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?

distance to eye in persp()
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 a vector of distances from the x,y,z point to the camera? I want this so I can plot clouds of points with the further ones in smaller plotsizes, and...

Deos anyone know of a summary of conformability rules? along with a specific problem
...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 guidelines available? And here is a specific problem: I would like to carry out logical comparisons between a (vector?) of length EYE and each row of a JAY by EYE object, obtaining a conforming JAY by EYE result of comparisons such as Obj[Jay,Eye] == Vec[Eye] Any thoughts on how to effect this would be welcome. Among many failed efforts, as.matrix(7 element Vec) == { an 8 row, 7 column data.frame} y...

Bird''s Eye integration in Mapstraction
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

Unbalanced Mixed Linear Models With Nested Stratum
...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,...

Off-topic -- an eye on a stats presentation for clinicians?
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.

feature idea for wine : stereo 3D

bugs or imperfect implementation?
...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 before. In the sequence below, drop1 didn't produce what I expected it to produce. data(HairEyeColor); lab<-dimnames(HairEyeColor) HairEye<-cbind(expand.grid(Hair=lab$Hair,Eye=lab$Eye, Sex=lab$Sex),Fr=as.vector(HairEyeColor)) HairEye.fit<-glm(Fr~.^2,poisson,HairEye) drop1(HairEye.fit) The following sequence however works.
