Prune tree (as.list) without altering

[bjoernhommel]

What options do I have to prune a tree without altering it? I found this answer on stackoverflow, but unfortunately I need to save the pruned tree as a list and as.list.Node() doesn't accept a pruneFun.
Thanks for the great package!

If it's not too big, you can first clone it, and then prune the clone.

This is what I'm currently doing but I would like to save resources since the tree is quite large and the app has performance issues because of it. Is there no other way?

Not currently, but I guess it would not be too difficult to build it into as.list.Node(). One would simply have to add a if condition to https://github.com/gluc/data.tree/blob/master/R/node_conversion_list.R#L140
Let me think about it. Or if you need it urgently, pls consider creating a pull request (I'm planning to release a new version to CRAN soon).
