Dear experts, I would like to plot a hierarchical clustering of 300 items. I had a distance matrix with dimension of 300*300. The 300 items were from 7 groups which I would like to label with 7 different colours in the plot.
>h<-hclust(as.dist(300_distance_matrix)) >plot(h,hang=-1,cex=0.5, col="blue") I used the above script to plot the result. The cluster was all blue, the 300 item names were all displayed blue. When I tried to specify the seven different colours, I found there was no option to get the names to be displayed in different colours. When I used graph and Rgraphviz packages, I could define a attribute list to specify the different group colours and plot a colourful graph. Is there any options in hierarchical clustering to do the same? Could someone kindly help me with this problem? Thanks in advance.
