draw_heatmap2 function

draw heatmap plots

print heatmap plots for expression matrix and group by group_list paramter

draw_heatmap2(exp, group_list, deg, my_genes = NULL, heat_union = TRUE, ...)

Arguments

• exp: A numeric matrix
• group_list: A factor with duplicated character or factor
• deg: a data.frame created by Differential analysis
• my_genes: genes for pheatmap
• heat_union: logical ,use union or intersect DEGs for heatmap
• ...: other parameters from draw_heatmap

Returns

a heatmap plot according to exp and grouped by group.

Examples

## Not run:

  geo$exp[1:4,1:4]
  geo$exp=log2(geo$exp+1)
  group_list=ifelse(stringr::str_detect(geo$pd$title,"MObese"),"MObese",
  ifelse(stringr::str_detect(geo$pd$title,"NonObese"),"NonObese","Obese"))
  group_list=factor(group_list,levels = c("NonObese","Obese","MObese"))
