Usage

add_labels(p, labs, plotGlPixelRatio = 8)

Arguments

p	A plotly scatter plot object
labs	Character vector of labels to match
plotGlPixelRatio	Integer passed to plotly.js config which controls pixel resolution of webGl rendering. Larger values increase resolution of points as well as file size.
