I would like to make a simple tree that uses math. The current way I do
it is to use the linguistics module, which gives access to the forest
package. Then I go to Insert > custom insets > Structure tree. I then
wrap the math I want to write in \protect. Attached is an example of
what I'm currently doing. It works, but I don't like writing out
\protect, and I have the feeling I'm asking the forest package to do
something it was not meant to do (include math).
Does someone recommend a different way?
I was in need of a decision tree diagram and found it rather hard to get
a satisfactory result. Maybe something of this is helpful to you.
In the preamble:
\forestset{
declare toks={elo}{},
my label/.style={
edge label={node[midway,above,text width=1.7cm,align=left]{#1}}
},
decision tree/.style={
for tree={
grow=east,
minimum size=2pt,
inner sep=2pt,
parent anchor=east,
child anchor=west,
l sep+=20mm,
s sep+=3mm,
edge path'={(!u.parent anchor) -- ([xshift=-18mm].child
anchor)\forestove{elo} -- (.child anchor)},
}
}
}
An example diagram (I added an instant preview around it):
{\small
\begin{forest} decision tree
[,label=$n_0$,draw
[,label=$n_3$,draw ,my label={$s_5,s_6$}
[$o_6$, my label=$s_6(n_3)$]
[$o_5$, my label=$s_5(n_3)$]
]
[,label=$n_2$,draw, my label={$s_3,s_4$}
[$o_4$, my label=$s_4(n_2)$]
[$o_3$, my label=$s_3(n_2)$]
]
[,label=$n_1$,draw, my label={$s_1,s_2$}
[$o_2$, my label=$s_2(n_1)$]
[$o_1$, my label=$s_1(n_1)$]
]
]
\end{forest}}
