[R] Frame Column to List (conversion)

[arun]

Hi,

Try this:

 test1<-read.table(text="
Fkh2 0.141  0.242  0.342
 Swi5 0.224  0.342  0.334
 Sic1 0.652  0.682  0.182
 ",sep="",header=FALSE)
 test1
#    V1    V2    V3    V4
#1 Fkh2 0.141 0.242 0.342
#2 Swi5 0.224 0.342 0.334
#3 Sic1 0.652 0.682 0.182
 geneLabel<-test1[,1]
 expValues<-as.matrix(test1[,2:4])
 colnames(expValues)<-NULL
###############################

 rownames(expValues)<-geneLabel

###############################

 expValues
#      [,1]  [,2]  [,3]
#Fkh2 0.141 0.242 0.342
#Swi5 0.224 0.342 0.334
#Sic1 0.652 0.682 0.182

Subject: [R] Frame Column to List (conversion)

Hi,

Input Format: excel file (XLS)
Column 1: Gene ID (alphanumeric)
Column 2 - 10 : (numeric data).

inData = read.xls ( <fileName>)
geneLabel =  inData [  , 1]         - column 1 stored in geneLabel
tempData = inData [ , 2: 10]  
expValues = data.matrix (tempData)   - convert frame into Matrix format

expValues has the matrix format needed for analysis.

I need to bind gene labels as .
I have this data in geneLablel  (extracted from data.frame)
How do I convert this to a list so i can use
rownames(expValues)  <-  ???????    

thanks
