Hi, this is how far I have come without practicel knowledge of dendrograms.
_________________________________________________________________________ # This dendrogram is from the demo of 'dendrogram', obtained by dput()! d3 <- structure(list(structure(list(structure(8L, members = 1L, height = 0, label = "Delaware", leaf = TRUE), structure(list(structure(1L, label = "Alabama", members = 1L, height = 0, leaf = TRUE), structure(18L, label = "Louisiana", members = 1L, height = 0, leaf = TRUE)), members = 2L, midpoint = 0.5, height = 15.4544491975612)), members = 3L, midpoint = 0.75, height = 16.8914988216046),structure(list(structure(list( structure(13L, label = "Illinois", members = 1L, height = 0, leaf = TRUE),structure(32L, label = "New York", members = 1L, height = 0, leaf = TRUE)), members = 2L, midpoint = 0.5, height = 6.23698645180507),structure(list(structure(22L, label = "Michigan", members = 1L, height = 0, leaf = TRUE), structure(28L, label = "Nevada", members = 1L, height = 0, leaf = TRUE)), members = 2L, midpoint = 0.5, height = 13.2973681606549)), members = 4L, midpoint = 1.5, height = 18.4173313943456)), members = 7L, midpoint = 2.625, height = 26.3634282396782, class = "dendrogram") plot(d3) str(d3) str(d3[[1]]) str(d3[[1]][[1]]) # The attributes of each node contain "midpoint" and "height" which are # the x and y coordinates. # par()$usr gives you the total coordinate range which can be seen in # the plot. attributes(d3[[1]])$midpoint attributes(d3[[1]])$height _______________________________________________________________________ We can't help you with your MatchPrint/MatchScore because we still haven't got any code from you. It helps if you prepare a workin example an put it in your email. run dput() on a fraction of your dendrogram. To obtain this fraction, use cut() E.g. try __________________________________ plot(cut(d3,h=20)$lower[[1]]) __________________________________ in the example above. The result of ________________________________________________________ # Cut the tree at height 20 and take the first sub-tree # # | # ------- # | | # | -------- # | | | #________________________ <--h # | | | # | | ------ # ----- | | | # | | | | | # # [[1]] [[2]] [[3]] # Sub-trees dput(cut(d3,h=20)$lower[[1]] __________________________________________________________ ...can be assigned to a variable to restore the object given to dput() Regards, Moritz On 10.04.2013 05:07, gunturus wrote: > But how would I get the coordinates of the leaves to draw a rectangle.
