Feature request: zoom function

[uribo]

ggtree is a cool package.

I want to expand the phylogenetic tree.
I'm glad and if there is a function, such as the zoom function of the ape package

[GuangchuangYu]

That's a nice idea. I will definitely implemented one maybe after supporting the beast output.

[GuangchuangYu]

It's now supported. Please try the following example:

require(ape)
data(chiroptera)
require(ggtree)
gzoom(chiroptera, grep("Plecotus", chiroptera$tip.label))

[GuangchuangYu]

I will close the issue. Pls reopen it if you have any further comments.

[GuangchuangYu]

for your information, the gzoom function was removed in current devel branch, since it can be easily done by treeio::tree_subset.
