Create a dataframe in R with different number of rows

In this article, we will explore how to create a data frame with different numbers of rows by using the R Programming Language.

How do we create the data frame?

data. frame() is a function that is used to create the data frame. By using these functions provided by R, it is possible to create the data frame easily. Some of the examples of creating the data frame with different numbers of rows are:

In the below example, we created the data frame with 4 rows by using the function ‘data. frame()’.

R

names = c("Alice", "Bob", "Charlie", "David")
ages = c(25, 30, 35, 40)
cities = c("New York", "Los Angeles", "Chicago", "Houston")
salaries = c(50000, 60000, 70000, 80000)

print("creating data frame with 4 rows")
result=data.frame(names,ages, cities, salaries)
print(result)

Output:

[1] "creating data frame with 4 rows"

    names ages      cities salaries
1   Alice   25    New York    50000
2     Bob   30 Los Angeles    60000
3 Charlie   35     Chicago    70000
4   David   40     Houston    80000

Now we create the data frame with 7 rows by using the function ‘data.frame()’.

R

#creating data frame
df = data.frame( rno=c(1:7),
                 id=11:17,
                Age =c(21, 22, 23, 24, 25, 26, 27),
                years =31:37)
print("creating data frame with 7 rows")
print(df)

Output:

[1] "creating data frame with 7 rows"

    rno   id     Age    years
1   1       11       21         31
2   2      12      22        32
3   3      13      23        33
4   4     14       24       34
5   5     15       25       35
6   6     16       26      36
7   7      17       27       37

In the below example, we created the data frame with 10 rows by using the function ‘data.frame()’.

R

# Creating dataframe 
data = data.frame(
  ID = 1:10, 
  Name = c("John", "Alice", "Bob", "Emily", "David", "Sophia", "Michael", 
            "Emma", "Daniel", "Olivia"),  
  Age = c(25, 30, 22, 35, 28, 27, 40, 33, 29, 31), 
  Gender = c("M", "F", "M", "F", "M", "F", "M", "F", "M", "F"),  
  stringsAsFactors = FALSE
               )
print("creating data frame with 10 rows")
print(data)

Output:

[1] "creating data frame with 10 rows"

    ID    Name     Age    Gender
1   1       John       25         M
2   2     Alice       30          F
3   3     Bob         22        M
4   4    Emily       35         F
5   5    David       28       M
6   6    Sophia     27        F
7   7    Michael   40        M
8   8    Emma      33        F
9   9    Daniel      29        M
10 10   Olivia        31         F

Conclusion

In conclusion, we learned about how to create a dataframe with different number of rows using R. R language offers versatile tools while dealing with data frames.
