I have a data frame which has the following data. data<-read.table("table.txt",header=TRUE) data X14A_U133A_StatPairs X14A_U133A_Detection X14B_U133A_Signal 1 AFFX-BioB-5_at 403.0 409.3 2 AFFX-BioB-M_at 757.3 574.4 3 AFFX-BioB-3_at 284.4 327.3 4 AFFX-BioC-5_at

Hello all, I am using the heatmap.2 function in the gplots package. I want to supress the reordering of the columns of the data matrix i pass to the function. I used the statement, heatmap.2(z,Colv=FALSE,dendrogram="row",col=redgreen(75)) where z, is the matrix of data. The output i want should have the rows reordered along with the dendrogram and the columns should be in the original

Hello all, I have a data file table.txt which i have attached. I am trying to pass the columns as arguments to a function "totnorm" where i am displaying a total normalization plot. The function is given below: totnorm<-function(x,y){scale<-sum(x)/sum(y);xlab<-colnames(x);ylab<-colnames(y);x1<-x[[1]];y1<-scale*y[[1]];plot(x1,y1,xlab=xlab,ylab=ylab,col=6, col.lab=4);}

[Re-directing to R-help, as this is more appropriate there.] I tried copying the snippet of data into the windows clipboard and tried it: > dat <- read.table("clipboard", header=T) > dat Name Weight Height Gender 1 Anne 150 65 F 2 Rob 160 68 M 3 George 180 65 M 4 Greg 205 69 M > str(dat) `data.frame': 4 obs.

I have another issue.i have a function which calculates the log2(col i /col2) value, where i stands for columns 3,4,...etc. data<-read.table("table.txt", header=TRUE) iratio<-function(x){ for(n in 3:ncol(data)){ z<-log2(data[x,n]/data[x,2]) } } Where x- the row number of the data frame(data). i want to store the ratios for each row in a object z, which can be accessed

Hello, I am trying to display a plot produced in R as part of an Applet. Stating more clearly, i want to display a scatter plot(X axis data:1,2,4,5 and Y-axis data:4,6,5, 7)produced in R as an Applet. How can this be done? Please let me know. Thanks, Vasu. [[alternative HTML version deleted]]

Hi all, I am trying to display a matrix of plots(images), for example a 3*3 matrix of 9 image plots, such that when a user clicks on a image i can show the enlarged plot. I tried the multiple graphic device(using mfcol=c(3,3) and mfg), but it creates multiple plots in a single image file. So, i won't be able to highlight a particular plot when the user clicks on it. To be more clear, can i

Hi all, Am trying to read data from a .txt file in such a way that i can access the column names too. For example, the data in the table.txt file is as below: Name Weight Height Gender Anne 150 65 F Rob 160 68 M George 180 65 M Greg 205 69 M i used the following commands: data<-scan("table.txt",list("",0,0,0),sep="") a<-data[[1]] b<-data[[2]]

Hello I m tryng to execute the code below and I have a problem with the R-Java connection.: import org.omegahat.R.Java.*; public class REvalSample { public static void main(String [] args) { String [] rargs = {"--slave", "--vanilla"}; System.out.println("Sample program to call R engine from Java"); ROmegahatInterpreter interp = new

Dear All, I'd like to write a little application in java wich should pass some commands and data to R and displays the results (tables and charts) in a java frame. First I wanted to work with Omegahat's SJava but had lots of issues already at the installation. Then I heard some rumors that SJava generally is not a very active project and runs rather buggy (that's true?). So my

Hi, I am working on a Java project that will run primarily on Windows. As part of the project I would like to use the R engine. However, from what I have seen on this list & the SJava list, installing SJava on Windows can be troublesome. As a result I was wondering if anybody had used DCOM to access R from a Java program on Windows (if it is all possible). Any pointers to documents and/or

Hi, I installed SJava 0.66-1 on my linux RH 7.2 machine. I am using R-1.7.1. I set LD_LIBRARY_PATH up then called library(SJava) and it was fine. But when I called .JavaInit(), I got weird error that states it could not find java/lang/Hashtable. The session is below and shows my java configuration. I am using j2sdk1.4.2_01 from Sun. Thank you very much. Weiming Zhang > .javaConfig

Hi there. I am trying to install SJava on my windows xp machine. I downloaded the windows source file SJava_0.69-0.tar.gz from the web site http://www.omegahat.org/RSJava/ I have folloed the XP command line instructions as directed in the table underneath the download link: cd $RHOME/src/library unzip SJava_0.69-0.zip cd SJava ./configure.win $RHOME cd $RHOME/src/gnuwin32 make pkg-SJava I

I'm excited about SJava, and I'ld love to get it working, but can't get past loading the package. .First.lib fails on this statement: > library.dynam("SJava", "SJava", "C:/PROGRA~1/R/rw1091/library") Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library

Hi all, I am new to R. I have been looking for a way to call R functions from Java or C. What I have found so far is: I can execute R commands in batch mode from a file and redirect the output to another file. However, I am not sure this is the way to do it. About C, is it true that I can only call R from a C process,only if that C process is invoked within R itself? So is it R->C->R ? If

hello, I am trying to install SJava on Windows XP as described on http://www.omegahat.org/RSJava/: at the level configure.win: $rhome/sjava/configure.win returned "argument 'c:/...' ignored" When i tried to install like the readme file, it returned in R > library(SJava) using JAVA_HOME = C:\Program Files\Java\j2re1.4.2_04 > .JavaInit() Error in .JavaInit() :

Hi, I have installed the SJava package (see http://www.omegahat.org/RSJava/ ) without any problem. I was able to run the examples (see http://www.omegahat.org/RSJava/examples/index.html ) from R, on my “R Linux server” and directly on the display of the server, But, if I run theses examples on an “X11 client”, under Linux or windows, with a “correct configuration” of the X11 client
