Error on random forest variable importance estimates
Hello, I am using the R randomForest package to classify variable stars. I have a training set of 1755 stars described by (too) many variables. Some of these variables are highly correlated. I believe that I understand how randomForest works and how the variable importance are evaluated (through variable permutations). Here are my questions. 1) variable importance error? Is there any ways

question regarding "varImpPlot" results vs. model$importance data on package "RandomForest"
Hi everyone, I have another "Random Forest" package question: - my (presumably incorrect) understanding of the varImpPlot is that it should plot the "% increase in MSE" and "IncNodePurity" exactly as can be found from the "importance" section of the model results. - However, the plot does not, in fact, match the "importance"

use "caret" to rank predictors by random forest model
Hi, I'm using package "caret" to rank predictors using random forest model and draw predictors importance plot. I used below commands: rf.fit<-randomForest(x,y,ntree=500,importance=TRUE) ## "x" is matrix whose columns are predictors, "y" is a binary resonse vector ## Then I got the ranked predictors by ranking

finding most highly transcribed genes - ranking, sorting and subsets?
Hello, I am not only interested in finding out which genes are the most highly up- or down-regulated (which I have done using the linear models and Bayesian statistics in Limma), but I also want to know which genes are consistently highly transcribed (ie. they have a high intensity in the channel of interest eg. Cy5 or Cy3 across the set of experiments). I might have missed a straight forward

transfer bug (#701 -> remote party hears alison, not me)
CVS HEAD from about 1 week ago. TDM30P and call through Nufone. I was talking and wanted to park the call and move to another phone to pick it up. I hit #701 instead of #700 though -- after a pause, I got a fast busy and the call was gone. When I called the person back, she said that Alison told HER that 701 was an invalid extension. I should have heard that though, not her. If I dial

using a package function inside another function
Hello all, I am trying to use the micEcon 'insertRow' function inside a function I have written. For example: insert_row_test <- function(m){ insertRow(m,nrow(m)+1,v=0,rName="test") } However, when I try to call the 'insert_row_test' function (after loading the micEcon package), it does not insert a row into the matrix I pass in.

adding a named column to a Matrix
Hello all, I am trying to use cbind to add a named empty column to a Matrix: outputmatrix <- cbind(outputmatrix,kog_id = seq(0,0,0)) The problem I have is that kog_id is a variable that has a value e.g. "KOG1234", but I when I try to use this to name the added column, it is named literally "kog_id" instead of "KOG1234".

colour of label points on a boxplot
Hi all, I have 6 datasets(dataframes Assem_ContigsLen7 through all_ContigsLen12) containing 3 columns (contig_id, contig_length, read_count). Each dataset is composed of 3 types of contigs (assemblies of genomic fragments), 1- all Bacterial fragments, 2 - all Viral fragments, 3 - mixed fragments. I identified the type of contig through a merge with another table with just contig_id and

heat map - how to import a graphic?
If I want to create a heat map where I have a graphic of a US State with county borders, how do I import and work with the graphic image? The reason I would like to use R is so I can then define color parameters and quickly produce heat maps that correspond to various data in dataframes.   Thanks.

Faster Sound Files
I'd like to increase the speed of the Asterisk sound files. Miss Alison talks a bit slow. I can use sox to increase the speed, but then the pitch changes and she starts to sound like a chipmunk. Any audio experts out there know how I can increase the speed a little bit, and change the pitch accordingly so that she sounds ... normal? Thanks Doug.
