Create One Dimensional Scatterplots in R Programming - stripchart() Function

Strip Chart is defined as one dimensional scatter plots or dot plots which is used as an alternative to box plot when sample sizes are small. It is created using the stripchart() function in R Language.

R - stripchart Function

Syntax: stripchart(x, data = NULL method, jitter )

Parameters: 

• x : value of data from which the plots are to be produced.
• data : a data.frame from which the variables in x value should be taken.
• Method : the method is basically used to separate coincident points.
• jitter : when method = “jitter” is used, jitter will produce the amount of jittering applied. 
   

Stripchart Function in R Programming Language

This example makes use of ToothGrowth database, stripchart() Function is implemented using ToothGrowth database.

Dataset:

Output:

 len supp dose
1 4.2 VC 0.5
2 11.5 VC 0.5
3 7.3 VC 0.5
4 5.8 VC 0.5
5 6.4 VC 0.5
6 10.0 VC 0.5
7 11.2 VC 0.5

The above code will print data set

Example 1: Simple Stripchart in R Programming

Output:

👁 Image

Example 2: Plot vertical stripchart in R Programming Language

Output:

👁 Image

Example 3: Change in point shapes (pch) and colors by groups

Output:

👁 Image

The above example will add the main title and axis labels and print colored stripcharts.

Example 4: Strip Chart for Multiple Numeric Vectors

In this example, we will use an iris dataset and list that contains the variables and plot stripchart plot.

Output:

👁 Image

Example : the stripchart() function can be used to create a one-dimensional scatterplot.

output :

👁 Image
