  I want to plot them side by side with the same order of genes 
  I tried
  > ht1 = Heatmap(heat1)
  > ht2 = Heatmap(heat2)
  > ht_list = ht1 + ht2
  > draw(ht_list, ht_gap = unit(1, "cm"))
  Warning message:
  Row names of heatmap 2 is not consistent as the main
  heatmap (1) 
  
  But I getting not the same order of genes
  
  Can you help me with this?
  
  user650: Please read through the ComplexHeatmap manual, especially the section on row and column orders: https://jokergoo.github.io/ComplexHeatmap-reference/book/a-single-heatmap.html#get-orders-and-dendrograms-from-heatmap
  You can use row_order and column_order following a draw() (which you can nest between a pdf(null) and dev.off() to disable drawing it on any device). That way, you'll be sure to get the right order from the first heatmap to use with the second.
  By nesting, I mean like so:
  h1 <- Heatmap(...)
  pdf(NULL)
  h1d <- draw(h1)
  dev.off()
  ro1 <- row_order(h1d)
  co1 <- column_order(h1d)
  
  Use whichever (row/column) order is appropriate to gene order.
