[R] Tree plot with percentages and hierarchies

[Jim Lemon]

Hi Joonas,
It is easy to display hierarchic classification using either the
plot.dendrite or sizetree functions (plotrix). At the moment, they
will only display counts, not percentages. It would not be too
difficult to reprogram either one to display percentages. Here are
examples with shortened category names (you'll see why):

Level_0 = c("Action X", "Action X", "Action X", "Action X", "Action
X", "Action X", "Action X", "Action X", "Action X", "Action X",
"Action X", "Action X", "Action X", "Action X", "Action X", "Action
X", "Action X", "Action X", "Action X", "Action X")
Level_1 = c("R1", "R1", "R1", "R1", "R1", "R1", "R1", "R1", "R1",
"R1", "R2", "R2", "R2", "R2", "R2", "R2", "R2", "R2", "R2", "R2")
Level_2 = c("Subr11", "Subr11", "Subr11", "Subr11", "Subr12",
"Subr12", "Subr12", "Subr12", "Subr12", "Subr12", "Subr21", "Subr21",
"Subr21", "Subr21", "Subr21", "Subr21", "Subr21", "Subr21", "Subr22",
"Subr22")
Level_3 = c("Subsubr111", "Subsubr111", "Subsubr111", "Subsubr112",
"Subsubr121", "Subsubr121", "Subsubr121", "Subsubr121", "Subsubr121",
"Subsubr121", "Subsubr221", "Subsubr221", "Subsubr221", "Subsubr221",
"Subsubr221", "Subsubr221", "Subsubr221", "Subsubr221", "Subsubr222",
"Subsubr222")

Levels = data.frame(Level_0 = Level_0, Level_1 = Level_1, Level_2 =
Level_2, Level_3 = Level_3)

library(plotrix)
plot.dendrite(Levels)
sizetree(Levels)
