Examples

# Draw a set of arrows
from <- cbind(
  runif(10, 0.2, 0.8),
  runif(10, 0.2, 0.8),
  runif(10, 0.2, 0.8)
)

to <- jitter(from, amount = 0.2)

# Setup base plot
p <- plot3js(label_axes = FALSE)

# Add arrows
p <- arrows3js(
  p, from, to,
  arrowhead_length = 0.06,
  arrowhead_width = 0.04,
  lwd = 0.01
)

# View the plot
r3js(p, translation = c(0, 0, 0.15), zoom = 2)
