Is there any way to use the Identify command with ggplot 2?

Question

In this case, everything is ok:

x <- 1:10 
y <- x^3
plot(x, y)
identify(x, y)

But, using qplot there are some troubles:

Answer 1

You may convert your plot, made with ggplot2 to interactive graph by using function ggplotly from package plotly, e.g.:

library(ggplot2)
library(plotly)

# Prepare data
x <- 1:10  
y <- x^3 
names <- paste("Point", LETTERS[x])

# Make a plot with `ggplot` as usual
qplot(x, y, label = names) 

# Convert it to interactive plot
ggplotly()

Then move your cursor over a point of interest and find information about it.
