How do you create a vector in R?

Answer 1

In R, you can create a vector using the c() function, which stands for "combine" or "concatenate". The c() function allows you to combine multiple values into a single vector. Here are a few ways to create a vector:

1. Creating a Numeric Vector:

numeric_vector <- c(1, 2, 3, 4, 5)  # Creates a numeric vector with values 1, 2, 3, 4, 5
 

2. Creating a Character Vector:

character_vector <- c("apple", "banana", "orange")  # Creates a character vector with strings "apple", "banana", "orange"
 

3. Creating a Logical Vector:

logical_vector <- c(TRUE, FALSE, TRUE)  # Creates a logical vector with values TRUE, FALSE, TRUE
 

4. Creating a Vector with Mixed Data Types:

mixed_vector <- c(1, "hello", TRUE)  # Creates a vector with numeric, character, and logical values
 

5. Creating a Sequence of Numbers: You can use the : operator to create a sequence of numbers. For example, to create a vector containing numbers from 1 to 5:

sequence_vector <- 1:5  # Creates a numeric vector with numbers 1, 2, 3, 4, 5
 

Once you have created a vector, you can perform various operations on it, such as indexing, subsetting, applying functions, and more. Vectors are fundamental objects in R and are widely used for data storage, manipulation, and analysis.
