Quick interactive phylogenetic tree in R

interative_tree.R

# LOAD LIBS ---------------------------------------------------------------
library(ape)
library(ggtree)
library(plotly)

# CREATE A TREE -------------------------------------------------------------
n_samples <- 20
n_grp <- 4
tree <- ape::rtree(n = n_samples)

# CREATE SOME METADATA ----------------------------------------------------
id <- tree$tip.label
set.seed(42)
grp <- sample(LETTERS[1:n_grp], size = n_samples, replace = T)
dat <- tibble::tibble(id = id,
                      grp = grp)

# PLOT THE TREE -----------------------------------------------------------
p1 <- ggtree(tree)

metat <- p1$data %>%
  dplyr::inner_join(dat, c('label' = 'id'))

p2 <- p1 +
  geom_point(data = metat,
             aes(x = x,
                 y = y,
                 colour = grp,
                 label = id))

plotly::ggplotly(p2)

I get an error with the aesthetic label: Warning: Ignoring unknown aesthetics: label

re @gotwals it seems as though the same general output can be achieved by switching to geom_text i.e.:

p2 <- p1 +
  geom_text(data = metat,
             aes(x = x,
                 y = y,
                 colour = grp,
                 label = id))

I don't know if you can see this, but this code works really well.
Is there any way to additionally display the bootstrap value or tip label as the ID of the sample rather than the group?
