I'm using the monoreg function (with weights) from the fdrtool package. How can I calculate the R square for this type of regression?

Hello, I am trying to write an R package for doing analysis of speaker recognition systems. The big thing in this line of research is a DET-plot (detection Error Trade-off, a ROC plot with qnorm() warped axes). My approach has been to make a class "det" and also a function "det()" that will prepare the data into the right class. Now loading the library doesn't like me

Hello, I am using fdrtool(x, statistic="pvalue") where x is a vector of chisq p-values. I can get this command to work with some x, but not with others. When it does NOT work, I get the following screen output: > fdrtool(pvals$Chi2.pval, statistic="pvalue") Step 1... determine cutoff point Step 2... estimate parameters of null distribution and eta0 Step 3... compute p-values

Hi, I've just started using R and fdrtool, and I'm not sure if the qvalues I'm receiving back are accurate. I performed fdrtool on pvalues obtained from a two way anova on proteomics data. So I have 266 data values (protein spots) for two factors (ft, vr, and the interaction) for each biological sample. One of the two factors (vr) has a highly significant effect with 119 protein

Hi! I would like to conduct a Cochran`s Q Test in R, but have not found any suitable function. My first idea was: J <- as.table(matrix(c(6,16,2,4),ncol=2, dimnames = list("C" = c("Favorable","Unfavorable"),"Drug A Favorable"=c("B Favorable","B Unfavorable")))) L <- as.table(matrix(c(2,4,6,6),ncol=2, dimnames =

Hi all, I am wondering if do exist a function in R that allow me to sample or choose randomly the rows (i.e., samples) inside a given matrix. Thank you very much in advance. Cheers, -- Gian [[alternative HTML version deleted]]

Hello, One of my functional tests looks like this: def test_presence_of_free_text profile = Profile.find :first post :edit, {:id => profile.id} assert_select "textarea", :name => "record[free_text_ec]" end The test results in a failure, because the element cannot be found. I''m pretty sure the element should be there, and I''ve tried

Hi everybody I would like a function as the "before_save" method in the model. But it must be the opposite. When I take out data from the database through the model, I want to call a function before the data are available in the controller. Can anyone help me? ---- >>>> thx <<<< ---- -- Posted via http://www.ruby-forum.com/.

Hello everyone, I would like to seek your advice regarding a build (or rather "configure") problem I am running into. For reference, tests are all relative to a build from a 1.8.26.0 tarball, on Debian Wheezy. I would like to understand if it is possible, and if any of you have tried, to build Asterisk from a subdirectory of the source tree, i.e., from a clean source tree # mkdir

Hi how can I validate a field only if another field is set to a specific value? I tried to use validates_length_of :fieldname, :maximum => 100, :if => :otherfieldname == ''myvalue'' But doesn''t work Thanks Paolo

Hi all, I would love to plot my data with R. I have abundance and frequency of fungal taxonomic data that should be plotted in the same graph. In Microsoft Excel is that possible but the graphic result is, as always, very poor. Is there a function that may let me plot these data in R? I have a matrix made of two columns, on is the relative abundance and the other is the relative frequency for

Dear List, I will appreciate any advice regarding how to convert the following numbers [I got in return by taxondive()] in numeric integers without the e.g. 6.4836e+01 abbreviations.

Hello there, I'd like to know if there are some way to gather statistics from samba4, like quantities of active users and other things that it can offer then use it in zabbix to generate some graphs and triggers. I can do somethings in smbstatus of samba3, but i couldn't find anything like this in samba4. is there anybody here who could do it? Thank's a bunch! -- *Gian Luca

Hello developers, I noticed that if I am running 'R', type "rm(list=objects())" and "gc()", 'R' will still be consuming (a lot) more memory than when I then close 'R' and re-open it. In my ignorance, I'm presuming this is something in 'R' where it doesn't really do a great job of garbage collection... at least not nearly as well as

Hi, I am writing a basic function to extract the z scores for some linear regression coefficients: zscore<-function( y, x) { lm<-lm( y ~ x ) z <- coef(lm)/sqrt(diag(vcov(lm))) return(z) } I would like to pass a dataframe to the function as a argument so the function call changes from zscore(df$y1,df$x1) to zscore(y1,x1,data=df) but I am not sure how to reference the data
