R Program to create a data frame from four given vectors

April 8, 2022, Learn eTutorial

This R program will help you to create a data frame from the given vectors.

What is a data frame in R?

A data frame is used for storing data tables which has a list of vectors with equal length. It is a matrix-like structure with different types of values or we can say that it is a table of data. It consists of vectors of the same length as columns in a table.

How to create a data frame in R?

Here we are explaining how to write an R program to create a data frame from four given vectors. We can use a built-in function data.frame() for creating a data frame in R. The function data.frame() creates data frames that have tightly coupled collections of variables.

The syntax of this function is 

data.frame(…, row.names = NULL, check.rows = FALSE,check.names = TRUE, fix.empty.names = TRUE,stringsAsFactors = default.stringsAsFactors()) 

Where dots(...) indicates the arguments are of either the form value or tag = value and row.names is a NULL or a single integer or character string.

How to create a data frame from four given vectors in the R program?

Below are the steps used in the R program to create a data frame from four given vectors. In this R program, we directly give the data frame to a built-in function. Here we are using variables contestant, points, tries, win for holding different types of vectors. Call the function data.frame() for creating a data frame.


STEP 1: Assign variables contestant,points,tries,win with vector values

STEP 2: First print original vector values

STEP 3: Call the in-built function data.frame(contestant,points,tries,win) and assign the result of the function to variable df

STEP 4: print the data frame df

R Source Code

                                          contestant = c('John', 'Michael', 'Albert', 'James', 'Kevin')
points= c(10, 9.2, 14, 12.5,18)
tries = c(1, 3, 2, 3, 2)
win= c('yes', 'no', 'yes', 'no', 'no')
print("Original data frame:")
df = data.frame(contestant,points,tries,win)  


[1] "Original data frame:"
[1] "John"    "Michael" "Albert"  "James"   "Kevin"  
[1] 10.0  9.2 14.0 12.5 18.0
[1] 1 3 2 3 2
[1] "yes" "no"  "yes" "no"  "no" 
  contestant points tries win
1       John   10.0     1 yes
2    Michael    9.2     3  no
3     Albert   14.0     2 yes
4      James   12.5     3  no
5      Kevin   18.0     2  no
