r2xcluster: Write to Xcluster file format

In ctc: Cluster and Tree Conversion.

Description

Converting data to Xcluster format

Usage

r2xcluster(data,labels=FALSE,description=FALSE,file="xcluster.txt")

Arguments

file	the path of the file
data	a matrix (or data frame) which provides the data to put into the file
labels	a logical value indicating whether we use the frist column as labels (NAME column for xcluster file)
description	a logical value indicating whether we use the second column as description (DESCRIPTION column for cluster file)

Details

Software Xcluster, made by G. Sherlock needs formatted input data like:

NAME    DESCRIPTION     GWEIGHT V2      V3      V4
EWEIGHT                         1       1       1
gbk01   Gene1           1       0.9     0.4     1.4
gbk02   Gene2           1       0.6     0.2     0.2
gbk03   Gene3           1       1.6     1.1     0.9
gbk04   Gene4           1       0.4     1       1
  

Line begining with EWEIGHT gives weights for each column (variable). Column GWEIGHT gives weights for each line (individuals).

Note

Xcluster is a C program made by Gavin Sherlock that performs hierarchical clustering, K-means and SOM.

Examples

##    Create data
set.seed(1)
m <- matrix(rep(1,3*24),ncol=3)  
m[9:16,3] <- 3 ; m[17:24,] <- 3    #create 3 groups
m <- m+rnorm(24*3,0,0.5)           #add noise
m <- floor(10*m)/10                #just one digits

r2xcluster(m)

## And once you have Xcluster program:

## Not run: 
  system('Xcluster -f xcluster.txt -e 0 -p 0 -s 0 -l 0')
  h <- xcluster2r('xcluster.gtr')
  plot(h,hang=-1)
  
## End(Not run)
