Hi I'm using the R packag ape to edit my newick trees. For my newick tree, I would like to remove values less than 80.

I'm able to  remove ALL labels using the following script:

library(ape)
tree <- read.tree("tree.nwk")
tree$node.label <- NULL
write.tree(tree, file = "tree_no_bootstrap.nwk")

...but somehow cannot find how to only delete bootstrap values less than 80.

Any advice would be much appreciated.
