Error: could not find function "opts"

[Simon Han]

library(ggplot2)
facebookData <- read.delim("FacebookNarcissism.dat", header = TRUE)
graph <- ggplot(facebookData, aes(NPQC_R_Total, Rating))
graph + geom_point() + opts(title = "geom_point()")

Error: could not find function "opts"

What's wrong?

opts() has been deprecated a long time ago. Use theme() options.
For setting a title, use ggtitle()

You are using very old ggplot2 code. opts() has long been deprecated.

labs() is the easiest way to change plot labels:
