Display Data Frame Name in ggplot2 Graph Title in R

To display data frame name in ggplot2 graph title, we can use ggtitle function and pass the name of the data frame.

For example, if we have a data frame called df that contains two columns say x and y and we can create a point chart between x and y then the plot with data frame name as title can be created by using the below mentioned command −

ggplot(df,aes(x,y))+geom_point()+ggtitle("df")

Example

Following snippet creates a sample data frame −

x<-rnorm(20)
y<-rnorm(20)
Scatter_data<-data.frame(x,y)
Scatter_data

Output

The following dataframe is created −

       x            y
1  -0.845697847   0.35455909
