R Language Learning notes--drawing with Ggplot2

data:The Diamonds dataset in Ggplot2, using a random sample to fetch 1000 samples, the code is as follows:

> Library (GGPLOT2)

> Data ("Diamonds")

> Head (Diamonds)

> set.seed (1234)

> Small <-diamonds[sample (Nrow (Diamonds), 1000),]

Histogram

> Ggplot (Small) +geom_histogram (Aes (X=price), fill= "Cornflowerblue", colour= "Black", binwidth= 1000)

Stacked Histogram

Use the "Cut" column in the data (divided into 5 grades, used to differentiate the quality of the diamond) to make a stacked histogram as follows:

>ggplot (small) +geom_histogram (Aes (X=price), fill= "Cornflowerblue", colour= "Black", binwidth= 1000)

Box Line diagram

> Ggplot (Small) +geom_boxplot (Aes (X=cut,y=price), fill= "Cornflowerblue", colour= "Black")

Bar chart

>ggplot (small) +geom_bar (Aes (x=clarity), fill= "Cornflowerblue", colour= "Black")

Pie chart

>ggplot (small) +geom_bar (Aes (X=factor (1), fill=cut), width=1) +coord_polar (theta= "Y")
