Question and answer were originally posted at Using 2+ legends from R to plotly / plot.ly

To edit what appears in the hover box:

# Load "plotly"
library(plotly)
# Open a Plotly connection
py <- plotly()

# Retrieve a Plotly graph in R
hover_text <- py$get_figure("PlotBot", 81)

str(hover_text$data)
# This list has 4 elements, which all have dimension (attribute) 'text'

# You can overwrite them one by one, say
hover_text$data[[1]]$text[1]
hover_text$data[[1]]$text[1] <- "US"

# If you need something functional, I would recommend defining the necessary
# functions and using sapply()

# Plotly graph with hover text we just edited
py$plotly(hover_text$data, kwargs=list(layout=hover_text$layout))
