[R] how to use vector of values to change row order of a heatmap

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

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
