acore: Extraction of alpha cores for soft clusters

In Mfuzz: Soft clustering of time series gene expression data

Description

This function extracts genes forming the alpha cores of soft clusters

Usage

acore(eset,cl,min.acore=0.5)

Arguments

eset	object of the class ExpressionSet.
cl	An object of class flcust as produced by mfuzz.
min.acore	minimum membership values of gene belonging to the cluster core.

Value

The function produces an list of alpha cores including genes and their membership values for the corresponding cluster.

Examples

if (interactive()){
### Data loaing and pre-processing
 data(yeast) # data set includes 17 measurements
 yeastF <- filter.NA(yeast) 
 yeastF <- fill.NA(yeastF)
 yeastF <- standardise(yeastF)

### Soft clustering and visualisation
cl <- mfuzz(yeastF,c=20,m=1.25)
acore.list <- acore(yeastF,cl=cl,min.acore=0.7)
 }
