How can I create interactive plots using Plotly in R?

You can create interactive plots in R using the Plotly library. First, install it using install.packages('plotly'). Then, you can use functions like plot_ly() to create various types of plots.

Can you show me an example of a scatter plot?

Sure! Here's a simple example:

library(plotly)

# Sample data
x <- rnorm(100)
y <- rnorm(100)

# Create scatter plot
plot_ly(x = ~x, y = ~y, type = 'scatter', mode = 'markers')

What about adding a trend line?

You can add a trend line using the add_lines() function. Here's how:

plot_ly(x = ~x, y = ~y, type = 'scatter', mode = 'markers') %>%
  add_lines(x = ~x, y = fitted(lm(y ~ x)), line = list(color = 'red'))

Can I customize the colors of the markers?

Yes, you can customize the colors by using the marker argument. For example:

plot_ly(x = ~x, y = ~y, type = 'scatter', mode = 'markers',
        marker = list(color = 'blue', size = 10))
