similar to: Removing Zeros from matrix:Problem fixed

Hi Everybody, I have a matrix of about 45 columns. Some of the rows contain zeros. Using >data1<-data[complete.cases(data),], I can remove the "NA" rows. But I am unable to tackle that of zeros. Can anybody give me an idea of how to remove rows containing zeros in a matrix. Thanks so much Best Ogbos [[alternative HTML version deleted]]

Hi, I am a Ph.D. student from Québec, Canada. I’m a beginner with R and Bioconductor. Until now the only experience I have is in analyzing microarray data using affy and limma packages. Now I am trying to analyze Rat Gene 10 st arrays and I would like to run RMA analysis and Smyth moderated t test on those arrays. Since no cdf official package is available for those arrays, after reading many

Hi, When adding an index to another one using add_indexes I get duplicates even though I use the :key attribute. For example: def test_add_indexes_uniqueness index1 = Ferret::Index::Index.new(:key => :id) index2 = Ferret::Index::Index.new(:key => :id) # Add two items with same id index1 << {:id => 23, :data => "This is the data..."}

Dear List, Let's say I have a list whose components are 2 matrices (as exemplified in the "mylist" object below). I'd like to create a list with components being 4 matrices based on an logical index vector. is there a way to simplify what I'm doing to obtain the results in "mylist2"? I'd like something that would work on an arbitrary number of elements in

Hi everyone, I have 2 environments (2 different R sessions) as described below: Session 1: Name of the environment: "CrlmmInfo" Objects in the environment: index1: logical index - length 238304 index2: logical index - length 238304 priors: list of 4 - (matrix 6x6, 2 vectors of length 6, vector of length 2) - all num params: list of 4: centers [238304 x 3 x

Dear All, I try to use Sweave to make a document. But when I use the Sweave() command on it and build a pdf with pdflatex (3.141592-1.40.3) my apostrophes are replaced by some gibberish (an 'a' with a hat on it, a capital A with a arc pointing upwards on it and a capital Y with two points on it). If I manually replace the apostrophes using the keyboard, I get a different looking

Hi, I'm trying to plot bar graphs with stacked columns marked with askterisks for certain columns, which follow certain criteria. I've gotten the stacked bar plots with Data set A (please refer to code below). However, I haven't figured how to put asterisks on columns based on some extra information (such as "used/unused") as in Data set B i.e. asterisks at the

Hi All, I have a whole lot of *.raw files in my working folder and I am doing the same analysis on each of those and want to save all the results in a single file. I am making some mistake here and can't figure out how to solve it. Say, the *.raw files are ABCD.raw, EFGH.raw, IJKL.raw ... The files are of this format ID PHI?? aa1? aa2? aa3 .... 1??? 1???? 1.3?? 2.0?? 1.0 2??? 0????

Hi, I'm using "by" to summarize by multiple groups, and want to extract the returned into a pretty dataframe. I'm trying to find a simple way to name the rows of the data frame. I'd like it to be something like index1.val1.index2.val2 where the index1 and index2 are the names of the indices and the val1 & val2 are names of possible values of the index. (the

This is assuming that match() and unique() will never disagree on equality between 2 floating point values. I believe they share some code internally (same hashing routine?), so maybe it's reliable.

Buenas, He creado dos andamios para dos tablas a la que accedo por index1 e index2 respectivamente. En cada index puedo hacer las tareas de añadir, borrar, ver lineas... pero me gustaria saber como se hace una busqueda mas compleja...es decir si tengo una tabla Productos y otra tabla descripciones y quiero mostrar en los productos con sus descripciones... he intentado en el index1 acceder a la

Hi Ogbos, Here is your sample data plotted in roughly the same way as the image. You can get the hours to start at the bottom, but it will require more code. swe$hour<-as.numeric(sapply(strsplit(swe$time,":"),"[",1)) swe$FD<-sample(1:2,nrow(swe),TRUE) library(plotrix) clock24.plot(swe$count,swe$hour,rp.type="s",radial.lim=c(3000,4010),

Dear All, This problem is over. Clock24.plot did the job. Thanks to all those who assisted me.

Good day all. This is to thank all those who have helped in fixing this problem. Starting with a text book was indeed a problem, however, that gave me a clue of what I was looking for. This, with your contributions added to other materials I got on the net, put me on the right track. Thank you so much.

Dear Christophe, Yes. It was helpful indeed. The four steps you outlined successfully helped me to install the newest version of R. I have been fiddling with this for days and I am quite grateful to all who contributed. I formally posted to r-help@r-project.org before somebody suggested posting to r-sig-debian@r-project.org. Best regards Ogbos 2011/5/31 Christophe Bonenfant

Dear list, Thanks for your time. I was surprised. While I was still waiting for your response, I entered R and discovered that it has been updated!!!! I hurried logged out and went home since I had overstayed battling with it. I wonder how the update happened with the numerous errors that were reported. I wish I will be able to find out, otherwise, I am off with my analysis with the new version :)
