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?

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, 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%",

Hi there, after several problems with installing R on a Debian server It now finally works at least roughly. With roughly I mean that the 'core' function do work properly, but I'm still having problems with the image export. When I try to call png(filename="my_file.png", width=800, height=300, pointsize=12, bg = "white") I just get the error message

Hi all, I'm a potential new user of R and have to know this before I start using it: SPSS does not let you do a Post Hoc analysis on repeated measures data. This is a problem for me, since that is what I will have to do. Will R let me do this? /Fredrik -- ----------------------------------------------------------------- Fredrik Karlsson, Research Student Department of Philosophy and

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.

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 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

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

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, 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

Hi all, This is a potentially very stupid question about MySQL <-> R interaction, but I have not been able to solve it. I'm just trying to connect R to my MySQL databse, and gets this: > library(RMySQL) Loading required package: methods > m <- dbDriver("MySQL") > con <- dbConnect(m,group="testdb") Process R segmentation fault at Wed Oct 16 07:04:30

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, I am using Sweave for chapters in my thesis that contain results. In the beginning of each chapter, I use this to load libraries I need. <<init,echo=FALSE,quiet=TRUE>>= library(gplots) library(Hmisc) library(e1071) @ What I want is, of course, to supress messages written by this code, but what I get in the end is X-init.tex with this the contents below. How do I really supress

Dear list, I need to convert this data.frame > names(codesM) [1] "key" "AMR.pa1.M" "AMR.pa2.M" "AMR.pa3.M" "AMR.pa4.M" [6] "AMR.pa5.M" "AMR.pa6.M" "AMR.pa7.M" "AMR.pa8.M" "AMR.pa9.M" [11] "AMR.pa10.M" "AMR.ta1.M" "AMR.ta2.M" "AMR.ta3.M"

Dear list, I have a two character vector with two different values in them (two each, that is). Naturally, when I use these vectors as grouping factors in a lattice plot, I get four panels. Now, one of the possible four combinations will never have data, so one panel will always be empty. So now my question is: can I force R / Lattice not to print it, and give me only the 3 filled panels? I have

Hi, I''m attempting to create a users statistics controller, and have saved up some questions regarding this for this post. So, please comment on any one of them, if not all :-) 1) Is there a library somewhere for doing stats? (e.g. mean, median, sd, skewness..) on an array in rails? 2) What library would you recommend for "publication ready" (i.e. not cheesy) histograms,

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.
