Scatter plot with ggplot2

October 31, 2010

(This article was first published on Ecological Modelling... » R, and kindly contributed to R-bloggers)

I decided to go use ggplot2 more frequently and go through everything. For future reference I will start a series of blog posts on ggplot2.

Scatter plot:

# producing some data
data <- data.frame(x=1:10, y=rnorm(10))
# initiating a plot
p <- ggplot(data, aes(x,y))
# plotting as it is
p + geom_point()
# adjusting size of the points
p + geom_point(aes(size=2))
# making the size dynamic
p + geom_point(aes(size=y))

In my next post, I will change the axis labels.
