Extraction of alpha cores for soft clusters
This function extracts genes forming the alpha cores of soft clusters
acore(eset,cl,min.acore=0.5)
eset |
object of the class ExpressionSet. |
cl |
An object of class |
min.acore |
minimum membership values of gene belonging to the cluster core. |
The function produces an list of alpha cores including genes and their membership values for the corresponding cluster.

### 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)
