How to create facetted plot with one facet displaying all data using ggplot2 in R?

To create facetted plot with one facet displaying all data using ggplot2 in R, we can follow the below steps −

• First of all, create a data frame.
• Then, create facetted plot using facet_grid function.
• After that, create the facetted plot with margins argument set to TRUE to display the plot with all data.

Create the data frame

Let's create a data frame as shown below −

 Live Demo

x<-round(rexp(25,1.25),2)
y<-round(rexp(25,1.89),2)
Grp<-sample(LETTERS[1:3],25,replace=TRUE)
df<-data.frame(x,y,Grp)
df

On executing, the above script generates the below output(this output will vary on your system due to randomization) −

x y Grp
1 2.32 0.47 C
2 0.96 0.01 C
3 0.34 0.49 A
4 1.11 0.75 C
5 0.57 0.63 C
6 0.47 0.38 B
7 0.69 0.06 A
8 1.12 1.66 C
9 0.62 0.81 C
10 0.05 0.60 C
11 0.50 0.05 A
12 0.06 0.18 A
13 0.08 1.30 C
14 2.22 0.13 C
15 0.03 0.13 C
16 0.06 0.24 C
17 0.57 1.04 A
18 0.50 0.09 C
19 1.10 0.36 B
20 0.10 0.00 B
21 1.28 0.42 A
22 1.56 0.34 A
23 1.38 0.15 A
24 0.54 0.03 B
25 1.81 1.85 A

Create the facetted plot

Use facet_grid function to create the facetted scatterplot between x and y −

x<-round(rexp(25,1.25),2)
y<-round(rexp(25,1.89),2)
Grp<-sample(LETTERS[1:3],25,replace=TRUE)
df<-data.frame(x,y,Grp)
library(ggplot2)
ggplot(df,aes(x,y))+geom_point()+facet_grid(~Grp)

Output

Create the facetted plot displaying one facet with all data

Using margins argument to create the facetted plot displaying one facet with all data as shown below −

x<-round(rexp(25,1.25),2)
y<-round(rexp(25,1.89),2)
Grp<-sample(LETTERS[1:3],25,replace=TRUE)
df<-data.frame(x,y,Grp)
library(ggplot2)
ggplot(df,aes(x,y))+geom_point()+facet_grid(~Grp,margins=TRUE)

Output
