Converting data.tree to JSON, simpler

tree conversion

#this has now become much simpler:

data(acme)
l <- acme$ToList()
#alternatively, you might prefer the "traditional" generic method:
l <- as.list(acme)

library(rjson)
j <- toJSON(l)
cat(j)

#as a side note: you can also convert a list to a Node:
a2 <- as.Node(l)

This is wonderful. I really appreciate it. With my little listviewer htmlwidget, you can do

#devtools::install_github("timelyportfolio/listviewer")
library(listviewer)

jsonedit(l)

and get a result like this
