Ggplot - Point (geom_point, geom_jitter) (Scatterplot)

Ggplot Graphic Plot

About

A geom point to create Scatterplot

Management

Size

geom_point(aes(size = qsec))

Jitter to reduce overplotting

current/geom_jitter.html is a shortcut for geom_point(position = “jitter”)

Points are jittered to reduce overplotting.

geom_jitter(width = 2, height = 5, alpha = 0.5)

Example

Categorical Data Ordered By Continuous Value

f = factor(c('six','one', 'two','three','four','five'))
x = c(4,1,5,2,10,3)

# We re[[order|order]] the factor by x
f <- reorder(f,x,sum) 
#  where:
#     * f is a factor of length n, 
#     * x is a vector of length n (It can also be negative if the sort must be descendant)
#     * the third parameter is a function (sum, median) that the lapply function supports.

ggplot()+geom_point(aes(x=x,y=f))
