R Programming - Create a Factor Corresponding to Women’s Height and weights Data

Last update on December 21 2024 10:08:28 (UTC/GMT +8 hours)

Write a R program to create a factor corresponding to height of women data set, which contains height and weights for a sample of women.

Sample Solution :

R Programming Code :

# Load the built-in 'women' dataset, which contains height and weight data
data = women

# Print a message indicating that the women data set will be displayed
print("Women data set of height and weights:")

# Print the 'women' dataset
print(data)

# Create a factor by dividing the 'height' variable into 3 intervals
height_f = cut(women$height, 3)

# Print a message indicating that the factor corresponding to height will be displayed
print("Factor corresponding to height:")

# Print the frequency table of the height factor
print(table(height_f))

Output:

[1] "Women data set of height and weights:"
   height weight
1      58    115
2      59    117
3      60    120
4      61    123
5      62    126
6      63    129
7      64    132
8      65    135
9      66    139
10     67    142
11     68    146
12     69    150
13     70    154
14     71    159
15     72    164
[1] "Factor corresponding to height:"
height_f
  (58,62.7] (62.7,67.3]   (67.3,72] 
          5           5           5

Explanation:

data = women

Purpose: Loads the built-in women dataset, which includes height and weight measurements for a sample of women, and assigns it to the variable data.

print("Women data set of height and weights:")

Purpose: Prints a message to indicate that the next output will be the data set showing the heights and weights of women.

print(data)

Purpose: Displays the women dataset, showing the height and weight of each sample.

height_f = cut(women$height, 3)

Purpose: Creates a factor variable height_f by dividing the height column of the women dataset into 3 intervals (bins). The cut function categorizes the heights into these intervals.

print("Factor corresponding to height:")

Purpose: Prints a message to indicate that the next output will be the factor levels corresponding to the height data.

print(table(height_f))

Purpose: Displays a frequency table of the height_f factor, showing how many women fall into each of the 3 height intervals.
