Hello, there,
R document for heatmap says that Rowv could be a vector of values to specify
the row order. However, I couldn't figure out how to apply it. A simple example
here:> b=as.data.frame(matrix(c(3,4,5,8,9,10,13,14,15,27,19,20),3,4))
> b
V1 V2 V3 V4
1 3 8 13 27
2 4 9 14 19
3 5 10 15 20
> row.names(b)=c("a","b","c")
> b
V1 V2 V3 V4
a 3 8 13 27
b 4 9 14 19
c 5 10 15 20
> heatmap(as.matrix(b))
What I got: "a" stays at the bottom of the heatmap.
Now I would like to put row "a" to the top row, how do I do that?I tried
provide a vector of values (all the possible combination of 1,2,3) to Rowv,
"a" is always stay at the bottom
Any input would be very helpful!
Thanks.
