I begin to use ComplexHeatmap to plot the dymamic change of values across different development stages in R.
-
I started from two dataframe, for example
df_1
anddf_2
, I merged them intodf_3
(df_3 <- rbind(df_1, df_2)
. I have plot Heatmap ondf_3
, but I want the heatmap to be able to split by data fromdf_1
anddf_2
.So My first question is: Is it possible to cluster the heatmap myself?
-
from the plot of
df_3
, I saw the dynamic change of values, some are increased as:stage1<stage2<stage3<stage4
; some are static:stage1=stage2=stage3=stage4
, some are are increase first but drop at later stage: iestage1<stage2>stage3>stage4
and so on.My second question is: Is there any way to extract the information (row# in
df_3
) of these subcluster, so I can know which
genes belong to which category?
Many thanks,
