# How to Find All Unique Combinations of 2 Vectors in R Programming (Example Code)

In this R programming tutorial you’ll learn how to create a data frame containing all unique combinations of two vectors.

## Creating Example Data

my_first_vector <- LETTERS[1:3] # Creating some vectors my_second_vector <- 1:5 |

my_first_vector <- LETTERS[1:3] # Creating some vectors my_second_vector <- 1:5

## Example: Create Data Frame with Unique Combinations

expand.grid(my_first_vector, my_second_vector) # Apply expand.grid function # Var1 Var2 # 1 A 1 # 2 B 1 # 3 AA 1 # 4 CDE 1 # 5 A 2 # 6 B 2 # 7 AA 2 # 8 CDE 2 # 9 A 3 # 10 B 3 # 11 AA 3 # 12 CDE 3 |

expand.grid(my_first_vector, my_second_vector) # Apply expand.grid function # Var1 Var2 # 1 A 1 # 2 B 1 # 3 AA 1 # 4 CDE 1 # 5 A 2 # 6 B 2 # 7 AA 2 # 8 CDE 2 # 9 A 3 # 10 B 3 # 11 AA 3 # 12 CDE 3
