Answer 1

In the Plotly docs in CRAN I discovered the function plotly_IMAGE.

Here is a example:

set.seed(100)
d <- diamonds[sample(nrow(diamonds), 1000), ]
p <- plot_ly(d, x = carat, y = price, text = paste("Clarity: ", clarity),
        mode = "markers", color = carat, size = carat)

plotly_IMAGE(p, width = 500, height = 500, format = "png", scale = 2,
             out_file = "~/desktop/test.png")

UPDATE

plotly_IMAGE works using Plotly server. A local solution is welcome.
