Create a Data Frame from four Vectors in R Programming

R Programming: Data frame Exercise-2 with Solution

Write a R program to create a data frame from four given vectors.

Sample Solution:

R Programming Code:

# Create a vector containing names
name = c('Anastasia', 'Dima', 'Katherine', 'James', 'Emily', 'Michael', 'Matthew', 'Laura', 'Kevin', 'Jonas')

# Create a vector containing scores
score = c(12.5, 9, 16.5, 12, 9, 20, 14.5, 13.5, 8, 19)

# Create a vector containing attempts
attempts = c(1, 3, 2, 3, 2, 3, 1, 1, 2, 1)

# Create a vector containing qualification status
qualify = c('yes', 'no', 'yes', 'no', 'no', 'yes', 'yes', 'no', 'no', 'yes')

# Print a message indicating the original data
print("Original data frame:")

# Print each vector
print(name)
print(score)
print(attempts)
print(qualify)

# Combine the vectors into a data frame
df = data.frame(name, score, attempts, qualify)

# Print the resulting data frame
print(df)

Output:

[1] "Original data frame:"
 [1] "Anastasia" "Dima"      "Katherine" "James"     "Emily"     "Michael"  
 [7] "Matthew"   "Laura"     "Kevin"     "Jonas"    
 [1] 12.5  9.0 16.5 12.0  9.0 20.0 14.5 13.5  8.0 19.0
 [1] 1 3 2 3 2 3 1 1 2 1
 [1] "yes" "no"  "yes" "no"  "no"  "yes" "yes" "no"  "no"  "yes"
        name score attempts qualify
1  Anastasia  12.5        1     yes
2       Dima   9.0        3      no
3  Katherine  16.5        2     yes
4      James  12.0        3      no
5      Emily   9.0        2      no
6    Michael  20.0        3     yes
7    Matthew  14.5        1     yes
8      Laura  13.5        1      no
9      Kevin   8.0        2      no
10     Jonas  19.0        1     yes                         

Explanation:

• Create a vector named name: Contains the names of 10 individuals.
• Create a vector named score: Contains the scores corresponding to each individual.
• Create a vector named attempts: Contains the number of attempts made by each individual.
• Create a vector named qualify: Indicates whether each individual has qualified ("yes" or "no").
• Print a message: Displays "Original data frame:" to indicate the start of the data frame output.
• Print the name vector: Shows the names of the individuals.
• Print the score vector: Shows the scores of the individuals.
• Print the attempts vector: Shows the number of attempts for each individual.
• Print the qualify vector: Displays the qualification status for each individual.
• Create a data frame named df: Combines the name, score, attempts, and qualify vectors into a structured data frame.
• Print the data frame df: Displays the combined data frame containing all the information for each individual
