What are some tips and tricks for using Plotly in R?

Here are some great tips for using Plotly in R: 1. Use plot_ly() for interactive plots. 2. Customize your layout with layout(). 3. Explore add_trace() for adding multiple data series.

Can you show me an example of a scatter plot using Plotly?

Sure! Here's a simple example:

library(plotly)

plot_ly(data = mtcars, x = ~wt, y = ~mpg, type = 'scatter', mode = 'markers')

How can I add a title and labels to my plot?

You can add a title and labels using the layout() function like this:

plot_ly(data = mtcars, x = ~wt, y = ~mpg, type = 'scatter', mode = 'markers') %>%
  layout(title = 'Weight vs MPG', xaxis = list(title = 'Weight'), yaxis = list(title = 'Miles Per Gallon'))

What about adding a regression line?

You can add a regression line using add_lines(). Here's how:

fit <- lm(mpg ~ wt, data = mtcars)
plot_ly(data = mtcars, x = ~wt, y = ~mpg, type = 'scatter', mode = 'markers') %>%
  add_lines(x = mtcars$wt, y = predict(fit), line = list(color = 'red'))
