Issue with function write.beast: not writing multiple BEAST trees

[tiagorsimoes]

Hello Dr. Yu,

Thanks for this incredible package! The function read.beast allows me to read either single (class: treedata) or multiple BEAST trees (treedata list). However, the function write.beast only allows me to export a single BEAST tree, and not multiple BEAST trees. When I try to export an object with multiple BEAST trees, I get the following error:

Error in UseMethod("Ntip") : no applicable method for 'Ntip' applied to an object of class "treedataList"

The write.nexus from ape allows me to export either a single or multiple standard formatted trees. As the write.beast is based on the latter, I believe this may be possible to fix, but I wanted to reach out to you to ask how to modify the function.

Best regards,

Tiago

Thanks for the feedback. Is it possible to request its inclusion?

Three years later and this seems still not implemented. It would be an extremely useful feature! Please consider adding this :-)

supported now.

For Ntip method of treedataList object, you can use Ntip(x[[1]]), and will be supported to directly use Ntip(x) in the future release version of the tidytree.
