Examples

data(abr1)
dat <- preproc(abr1$pos[,200:400], method="log10")  
cls <- factor(abr1$fact$class)

## feature selection without resampling
fs <- feat.mfs(dat, cls, method=c("fs.anova","fs.rf","fs.rfe"), 
               is.resam=FALSE)
## rank aggregation 
fs.1 <- feat.agg(fs$fs.rank)
names(fs.1)
