geom_tiplab does not work with geom_tree

[brj1]

Hi Guangchuang,

I found a weird bug today when I was trying to make a tree with scaled branch lengths based on node dates. I was plotting my trees using fortify(tree) %>% ggplot() + geom_tree() instead of ggtree(tree) and I found I could not get geom_tiplab to work. See the following example:

library(ggtree)
library(ape)

set.seed(0)
tree <- rtree(5)

# The following works
fortify(tree) %>% ggtree() + geom_tiplab()

# But this fails
fortify(tree) %>% ggplot() + geom_tree() + geom_tiplab()

# And so does this
ggplot(tree) + geom_tree() + geom_tiplab()

Below is the error message I get for both failing lines above

Error in layout == "circular" :
comparison (1) is possible only for atomic and list types

I am using the dev version of ggtree.
