How to display the values of two columns of an R data frame separately in a plot?

R Programming Server Side Programming Programming

In general, the scatterplot is used to visualize the relationship between two columns of an R data frame but if we want to display the two columns separately not as a pair then we need to use matplot function. This function will create a plot for all the values in the two columns and represent them by their column number.

Consider the below data frame −

Example

Live Demo

set.seed(222)
x<-rnorm(20,2,0.5)
y<- rpois(20,2)
df<-data.frame(x,y)
df

output

x y
1 2.7438785 3
2 1.9990540 4
3 2.6905104 3
4 1.8098932 3
5 2.0920681 1
6 1.8765521 3
7 1.3922195 4
8 2.7807025 2
9 2.2136551 0
10 1.3994882 4
11 2.5262292 0
12 1.3474682 2
13 1.6536962 2
14 2.3013244 4
15 1.9011235 1
16 1.4070627 0
17 0.9972435 1
18 2.0037549 1
19 2.2597452 4
20 1.6268523 2

Creating the plot for all the values in the two columns of data frame df −
