# Using c() function
numeric_vector <- c(1, 2, 3, 4, 5)
character_vector <- c("apple", "banana", "orange")
# Using vector() function
logical_vector <- vector("logical", length = 3)
logical_vector[1] <- TRUE
logical_vector[2] <- FALSE
logical_vector[3] <- TRUEWe can access the vector with index number inside a [] bracket.
numeric_vector <- c(1, 2, 3, 4, 5)
# Accessing elements of a vector
first_element <- numeric_vector[1] # Access the first element
second_element <- character_vector[2] # Access the second element
Operators are used in vectors to perform various operations.
Functions are a built in methods that performs operations fast and easy.
Operation
Syntax
Description
Example
Addition
vec1 + vec2
Element-wise addition of two vectors.
c(1, 2, 3) + c(4, 5, 6)
Subtraction
vec1 - vec2
Element-wise subtraction of one vector from another.
c(4, 5, 6) - c(1, 2, 3)
Multiplication
vec * scalar or vec1 * vec2
Scalar multiplication or element-wise multiplication.
c(1, 2, 3) * 2
Division
vec / scalar or vec1 / vec2
Scalar division or element-wise division.
c(4, 5, 6) / 2
Exponentiation
vec^exp
Element-wise exponentiation.
c(1, 2, 3)^2
Concatenation
c(vec1, vec2)
Concatenates two or more vectors.
c(1, 2, 3, 4, 5, 6)
Sum
sum(vec)
Calculates the sum of vector elements.
sum(c(1, 2, 3))
Mean
mean(vec)
Calculates the mean (average) of vector elements.
mean(c(1, 2, 3))
Length
length(vec)
Returns the number of elements in a vector.
length(c(1, 2, 3))
Square Root
sqrt(vec)
Calculates the square root of each element.
sqrt(c(1, 4, 9))
Vectorized Functions
vec1^2, sqrt(vec)
Applying functions to each element vectorized.
c(1, 2, 3)^2, sqrt(c(1, 4, 9))
# Creating vectors
vec1 <- c(1, 2, 3)
vec2 <- c(4, 5, 6)
# Vector addition
result_addition <- vec1 + vec2
print("Vector Addition:")
print(result_addition) # Output: 5 7 9
# Scalar multiplication
result_scalar_multiplication <- vec1 * 2
print("\nScalar Multiplication:")
print(result_scalar_multiplication) # Output: 2 4 6
# Element-wise exponentiation
result_exponentiation <- vec1^2
print("\nElement-wise Exponentiation:")
print(result_exponentiation) # Output: 1 4 9
# Concatenation
combined_vector <- c(vec1, vec2)
print("\nConcatenation:")
print(combined_vector) # Output: 1 2 3 4 5 6
# Sum and Mean
sum_of_vector <- sum(vec1)
mean_of_vector <- mean(vec1)
print("\nSum of Vector:", sum_of_vector) # Output: 6
print("Mean of Vector:", mean_of_vector) # Output: 2
# Applying a function to each element vectorized
square_root_vector <- sqrt(vec1)
print("\nSquare Root of Vector:")
print(square_root_vector) # Output: 1 1.414214 1.732051The Concepts and codes you leart practice in Compilers till you are confident of doing on your own.
