Hi all,
I am trying to produce a heatmap to display clustering of similar rows in
the data given below. For each given row, different colors are used to
represent the corresponding column value. I want to display the values of
the colors in the form of a color key added to the heatmap. Is there anyway
of doing this?
> z[1:10,1:6]
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 403.0 409.3 611.5 569.2 536.6 580.2
[2,] 757.3 574.4 826.7 595.3 755.2 956.0
[3,] 284.4 327.3 421.6 336.6 391.3 412.6
[4,] 2314.2 1685.3 2264.7 2204.1 2233.1 2458.4
[5,] 1574.5 1273.0 1484.6 1321.2 1474.7 1774.1
[6,] 2333.7 1796.8 2464.5 2372.5 2095.9 2735.7
[7,] 13673.9 11463.9 13624.7 14513.9 12934.1 16293.1
[8,] 17778.8 15248.8 19977.2 19613.4 18609.1 18988.2
[9,] 31056.6 24869.9 30773.4 32918.6 34412.1 33954.6
[10,] 36.3 69.8 92.0 52.0 57.3 64.9
Also, is it possible to get the order in which the rows will be clustered ,
starting with the first rows joined into a group and then followed by other
grps added. I thought i could extract the order by using $rowInd, but looks
like it's the order in which the rows are reordered in the map. Please let
me know how to do this.
Thanks,
Vasu.
