Hi all, I've got at really basic Q for you all: How do I produce a 3D plot in R? Like the one in the screenshot on the R-project wab-page. What is the command? /Fredrik -- ----------------------------------------------------------------- Fredrik Karlsson, Research Student Department of Philosophy and Linguistics Ume?

Hi all This seems like a very easy question, but I have not found a simple answer to it: If you have a dataframe, how to you plot two of then in different colors depending on a third variable?

Hi all I'm trying to complete a textbook example originally designed for SPSS in R, and I therefore need to find out how to compute an unbalanced ANOVA in R. I did a search on the mailinglist archives an found a post by Prof. Ripley saying one should use the lme function for (among other things) unbalanced ANOVAs, but I have not been able to use this object. My code gives me an error.. Why

Hi all! I want to do some logistic regression. Is there a fintion in R that does this, or do I have to do the variable conversion by hand?

Hi, I am trying to use rsync to migrate homefolders from one server to another. For this I use: > rsync --rsh="ssh -l root" -vaz beaucent.ling.umu.se:/export/home/ . Which works fine until I get to some files where the user has, unfortunatelly, used a non-ascii character in the file name: --- snip -- ...

Dear list, I would like to create histograms for up to three groups, with distincive colour/pattern, in a trellis panel. However, I have not been able to find a way to do this. histogram does not seem to have a group argument. Please help. /Fredrik

Dear list, I have been working on a report with around 60 images in it, and everything has been fine, until now. I find that the image output that is produced by odfWeave produces images that are NOT readable by OpenOffice or NeoOffice. I get empty boxes with Read-Error written in them. While generating the file using odfWeave, I can see them being generated on the screen, and they all seem fine.

Dear list, Sorry for asking this very silly question on the list, but I seem to have made my life complicated by going into string manipulation in vectors. What I need is to get the last part of a sting (the two last tokens, separated by a space), and of course, this should be done for all strings in a vector, creating a new vector of exual size. So, a <- c(" %L H*L L*H H%",

Dear list, I am leaving my old position and now need to convert my R data frames into a format that can be used by an SPSS user replacing me, without running into conversion problems. The data set consists of strings in UTF8 encoding and values in double precision floats. The data set is not terribly large, but I had bit problems getting it into R due to the large number of unfortunate characters

Dear all, how can I perform a post hoc analysis for ANOVA with repeated measures (in presence of a balanced design)? I am not able to find a good example over internet in R...is there among you someone so kind to give me an hint with a R example please? For example, the aov result of my analysis says that there is a statistical difference between stimuli (there are 7 different stimuli). ...I

Dear list, I have a table that I would like to convert to latex for inclusion into a Sweave file. > round(ftable(prop.table(xtabs(~agemF + votcat + Type , data=work),margin=2))*100,1) Type Voiced Voiceless unaspirated Voiceless aspirated agemF votcat 18 - 24 Prevoiced 2.6 8.7

Some attribute x from 17 individuals was recorded repeatedly on 6 time points using a Likert scale with 7 distractors. Which statistical test(s) can I apply to check whether the changes along the 6 time points were significant? set.seed( 123 ) x <- matrix( sample( 1:7, 17*6, repl=T ), nrow = 17, byrow = TRUE, dimnames = list(1:17, paste( 'T', 1:6, sep='' )) ) I found

Hi, is there a specific/appropriate function/package to perform post hoc tests when running a two way repeated measures anova? I'm looking for something that will be equivalent to the 'TukeyHSD()' for between subjects anova (with 'aov()'). For one way repeated measures anova, the 'pairwise.t.test()' function seems to work correctly but the results are questionable for

Dear list, I'm making my current code more generic and would like some advise. The basic problem is subset and the name of the column to be compared for selection. What I've come up with is > data(mammals) > set <- bottompremolars" > subset(mammals, eval(parse(file="",text=set)) > 2) This seems a bit odd. Is there a nicer way? /Fredrik

Hi everyone, I am fairly new to R, and I am aware that others have had this problem before, but I have failed to solve the problem from previous replies I found in the archives. As this is such a standard procedure in psychological science, there must be an elegant solution to this...I think. I would much appreciate a solution that even I could understand... ;-) Now, I want to calculate a

Hi, I am trying to get into this REST thing, I have a nested resource whith the following route: ActionController::Routing::Routes.draw do |map| map.resources :members map.resources :clubs do |club| club.resources :members end map.connect '':controller/:action/:id'' map.connect '':controller/:action/:id.:format'' end Everything worked ok for this

Dear list, I am sorry for asking you this, but I am trying to do again what I thought I have done before, although this time it does not work. So, given the data set: > testdf <- data.frame(grfak=sample(c("One","Two"),size=100,replace=TRUE), panfak= sample(c("Yes","No"),size=100,replace=TRUE), xfak=

Dear list, I am trying to plot a barchart (from lattice) in B & W, with 10 categories per bar. It seems that the colours are recycled after reachingcategory number 7, which creates a problem interpreting the chart. I therefore have two questions: 1) How do I get more shades? 2) Does anyone have a theme to share with me with distinctive shades in Black & White? Thankful for all the

Hi, This is just kindof a RoR question, but since you all potentially do the same things as I do, I thought I''ll ask here.. Im trying to use the boolean type in the database. Migrations is no problem, it even converts the 0/1 values from my import CSV to false and true. However, I cannot make the :conditions part of a find work: Loading development environment (Rails 2.0.2) >> c
