Did you look at the help page?

I get

Usage:

      heatmap.2 (x,

                           # dendrogram control
                           Rowv = TRUE,
                           Colv=if(symm)"Rowv" else TRUE,
                           distfun = dist,
                           hclustfun = hclust,

Then ?hclust gives me

Usage:

      hclust(d, method = "complete", members=NULL)
