Hello,
I'm doing the Exploratory Data Analysis course in Udacity(R). In lesson 4 there's a chapter on "Alpha and jitters", where the tutor explains that the command geom_jitter adds noise to the data. What does that mean? What is the logic behind how the noise is added?
Sample code:
ggplot(aes(x = age, y = friend_count), data = fb) +
geom_jitter(alpha = 1/20)+
xlim(13,90)Regards
