How to create a scatterplot with larger distance between facets in R?

By default, the distance/space between facets created by using ggplot2 is very less and it becomes a little uneasy for viewers to separately read the facets. Therefore, to deal with this problem we can increase the space between facets and it can be done with the help of theme function as shown in the example below.

Example

Following snippet creates a sample data frame &miuns;

x<-rnorm(20)
y<-rnorm(20)
Group<-sample(c("Male","Female"),20,replace=TRUE)
df<-data.frame(x,y,Group)
df

Output

The following dataframe is created −

       x         y          Group
1   1.2867663   0.55866491  Male
2   0.7391027  -0.34618436  Female
3   0.5235874  -0.74887181  Female
4   0.5888993  -0.68957351  Male
5  -0.3590756   0.75730314  Female
6  -0.5554565  -0.38544639  Male
7   0.4637831  -1.68509743  Male
8  -0.3665099  -0.26642702  Male
9  -0.4825639   0.63628373  Male
10 -1.1191989   1.55902395  Female
11 -0.5730155   0.04807617  Male
12  1.0237728  -0.84262752  Female
13 -1.2894423   1.97032059  Female
14 -0.6856492  -0.78864269  Male
15 -0.5171276   0.23602206  Female
16 -0.7189031   0.81558755  Female
17  1.4954506  -0.64333891  Female
18 -1.1988800  -0.07535623  Male
19 -0.8260068   0.73747420  Male
20 -2.0534583  -0.63682645  Female

To load ggplot2 package and create point chart between x and y with facets defined by Group column, add the following code to the above snippet −

library(ggplot2)
ggplot(df,aes(x,y,color=Group))+geom_point()+facet_grid(~Group)

Output

If you execute all the above given snippets as a single program, it generates the following Output −

To create point chart between x and y with facets at a larger distance defined by Group column, add the following code to the above snippet −

ggplot(df,aes(x,y,color=Group))+geom_point()+facet_grid(~Group)+theme(panel.spacing=unit(3,"lines"))

Output

If you execute all the above given snippets as a single program, it generates the following Output −
