ggplot2 heatmap : how to preserve the label order ?
- by Tg
I'm trying to plot heatmap in ggplot2 using csv data following casbon's solution in
http://biostar.stackexchange.com/questions/921/how-to-draw-a-csv-data-file-as-a-heatmap-using-numpy-and-matplotlib
the problem is x-label try to re-sort itself. For example, if I swap label COG0002 and COG0001 in that example data, the x-label still come out in sort order (cog0001, cog0002, cog0003.... cog0008).
Is there anyway to prevent this ? I want to it to be ordered as in csv file
thanks
