Hi!

I use this tutorial on this site http://www.bioconductor.org/help/workflows/rnaseqGene/:

library("genefilter")
topVarGenes <- head(order(-rowVars(assay(rld))),35)

Why -rowVars?

See the man page for the function if you have questions about its behavior: ?order. The default for order() is small to large so adding a minus sign sorts large to small.
