Question

How can I 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 examples:

1. Numeric Vector:

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

2. Character Vector:

names <- c("John", "Alice", "Bob")  # Creates a character vector with names "John", "Alice", "Bob"
 

3. Logical Vector:

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

4. Vector with Mixed Data Types:

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

You can also create a sequence of numbers using the : operator. For example:

sequence <- 1:10  # Creates a numeric vector with numbers from 1 to 10
 

Once you have created a vector, you can perform various operations on it, such as indexing, subsetting, applying functions, and more.
