What is match() Function in R Last Updated : 16 May, 2024 Comments Improve Suggest changes Like Article Like Report match() function in R Language is used to return the positions of the first match of the elements of the first vector in the second vector. If the element is not found, it returns NA. Syntax: match(x1, x2, nomatch) Parameters: x1: Vector 1 x2: Vector 2 nomatch: value to be returned in case of no match Example 1: Python3 1== # R program to match the vectors # Creating vectors x1 <- c("a", "b", "c", "d", "e") x2 <- c("d", "f", "g", "a", "e", "k") # Calling match function match(x1, x2) Output: [1] 4 NA NA 1 5 Example 2: Python3 1== # R program to match the vectors # Creating vectors x1 <- c("a", "b", "c", "d", "e") x2 <- c("d", "f", "g", "a", "e", "k") # Calling match function match(x1, x2, nomatch = "-1") Output: [1] 4 -1 -1 1 5 Comment More infoAdvertise with us Next Article What is match() Function in R N nidhi_biet Follow Improve Article Tags : R Language R Vector-Function Similar Reads What Is The Data() Function In R?
