I have assayed the concentrations of various metal elements in different anatomic regions of two strains of mice. Now, for each element, in each region, I want to do a t test to find whether there is any difference between the two strains. Here is what I did (using simulated data as an example): # create the data frame > elemconc = data.frame(expand.grid(id=1:3, geno=c('exp',

Hola buenas tardes: Vuelvo a solicitar su ayuda porque no puedo saber que pasa. Estoy usando el documento 'Regresión Logística Categor/Tema 4 Cate.pdf como guía y el ejemplo que ustedes conocen de los cangrejos (crab.txt). Cargo los datos, los guardo en un data frame llamado tabla; al pedir tabla[1:5,] obtengo: color spine width satell weight 1 3 3 28.3 8 3050 2 4

Dear all, I wonder what's special about spinograms {vcd} that prevents me from using it the way I do with other plots. I do: > spine(f.speaker.identity ~ x.log.lengthening, > data=ms,breaks=45,gp=gpar(fill=c("red","green")),xlab="length difference > (log ms)",ylab="speaker") > curve(0*x,add=T) Error in plot.xy(xy.coords(x, y), type =

I want to compare the fit of a quadratic model to continuous data, with that of a cubic spline fit. Is there a way of computing AIC from for e.g. a GAM with a smoothing spine, and comparing this to AIC from a quadratic model?

If yes, how do I set it up in the yml file? Thanks. - amateur Railist -------------- next part -------------- An HTML attachment was scrubbed... URL: http://wrath.rubyonrails.org/pipermail/rails/attachments/20060818/6690a4e2/attachment.html

Dear R users, I have a 51 by 51 matrix of p-values (named as pvalue_MA). I want to present graphically this matrix in a plot (filled contour plot) where both axes represent probabilities. I have also added a grid in this plot. I want to highlight in white the cells of the grid that represent p-values smaller than the (common) significance threshold, 0.05. The code from this plot is colored in

Dear all, I am trying to create a list, where each list element is a vector of different length arrays that contain 2by2 matrices. To be more specific there are 11 treatments that are compared with placebo (we have 11 comparisons) and each comparison is studied by a different number of trials and each trial has a different number of missing participants in both arms. The length of the list is

Dear useRs, a new version of the vcd package (0.9-5) is now available from CRAN. Apart from (a lot of) bug fixes, it includes the following new features (some of them have 'silently' been included in previous bug fix releases): * Improved documentation: - an introductory vignette on the strucplot framework (including mosaic, association and sieve plots) - special vignettes on

I am trying to do this, but it won't work: > library(lattice) > elemconc = data.frame(expand.grid(id=1:20, geno=c('exp', 'wt'), region=c('cor', 'cr', 'spine'), elem=c('fe', 'cu', 'zn')), conc=rnorm(360, 10)) > elemconc$geno = factor(elemconc$geno) > elemconc$region = factor(elemconc$region) > for (i in

Hi Has anyone tried to fit a thin plate spine to a triangular plot before? I'm having trouble working out a piece of code to make it possible with three axes. I have done it before with two axes. I've found a package I prefer that makes triangular plots (plotrix) using the triax.plot() function. An example of some data and the plot follows: graph.data<-data.frame(a=c(9,6.2,

Hi, I'm trying to work through a Nested ANOVA for the following scenario: 20 males were used to fertilize eggs of 4 females per male, so that female is nested within male (80 females used total). Spine length was measured on 11 offspring per family, resulting in 880 measurements on 80 families. I used the following two commands: summary(aov(Spinelength ~ Male*Female)) and

I want to make a multi-dimensional array. To be specific I want to make the following array results<-array(0,dim=c(2,2,64,7)) This is the code I have created but it gives no result due to the error "subscript out of bound". x<-rep(7,7) # Missingness in intervention y<-rep(7,7) # Missingness in control

Hi People, I am new to this entire setup and I am running Fedora17 on my Linux machine. I am trying to do a college course at home with Stanford.edu on eclipse & Karel package for intro to programming. As I start the install of the 1st package which is Java 1.6 JRE installer for the PC <http://www.stanford.edu/class/cs106a/software/jre-6u2-windows-i586-p.exe> It gets stuck on step 3.

well, thank you to all with the propane... "user head space error" is a problem, but I can see past this level of ... how do you say, never mind. anyhow* Your wine is VERY old. !!Yes, got one, and will compile once I work out how to... you can get a newer version at http://www.winehq.com/download.shtml you can also get the latest version of the source and documentation at

Another newbie question I got the 1 minute spine interpolation and 15 mean aggregation working with many thanks to Gabor Grothendieck using Zoo functions. I got a tip from Hasan Diwan to look at xts but it seemed I would make better progress using code from Gabor. Now I'm having trouble plotting this zoo object. I'm thinking I want a function to "split" the zoo object back to

Dear useRs, I am happy to announce that my package "plotluck" is now on CRAN: [1]https://cran.r-project.org/web/packages/plotluck/ The aim of the package is to let the user focus on what to plot, rather than on the "how" during exploratory data analysis. Based on the characteristics of a data frame and a formula, it tries to automatically choose the most suitable t ype of
