Syntax: replace(x, list, values) Parameters: x: vector list: indices values: replacement values Example 1: Python3 # R program to illustrate # replace function # Initializing a string vector x <- c("GFG", "gfg", "Geeks") # Getting the strings x # Calling replace() function to replace # the word gfg at index 2 with the # GeeksforGeeks element y <- replace(x, 2, "GeeksforGeeks") # Getting the new replaced strings y Output : [1] "GFG" "gfg" "Geeks" [1] "GFG" "GeeksforGeeks" "Geeks" Example 2: Python3 # R program to illustrate # replace function # Initializing a string vector x <- c("GFG", "gfg", "Geeks") # Getting the strings x # Calling replace() function to replace # the word GFG at index 1 and Geeks at # index 3 with the A and B elements # respectively y <- replace(x, c(1, 3), c("A", "B")) # Getting the new replaced strings y Output: [1] "GFG" "gfg" "Geeks" [1] "A" "gfg" "B" Create Quiz Comment K Kanchan_Ray Follow 1 Improve K Kanchan_Ray Follow 1 Improve Article Tags : R Language R Vector-Function Explore IntroductionR Programming Language - Introduction 4 min read Interesting Facts about R Programming Language 4 min read R vs Python 5 min read Environments in R Programming 3 min read Introduction to R Studio 4 min read How to Install R and R Studio? 4 min read Creation and Execution of R File in R Studio 5 min read Clear the Console and the Environment in R Studio 2 min read Hello World in R Programming 2 min read Fundamentals of RBasic Syntax in R Programming 3 min read Comments in R 3 min read R-Operators 5 min read R-Keywords 2 min read R-Data Types 5 min read VariablesR Variables - Creating, Naming and Using Variables in R 5 min read Scope of Variable in R 5 min read Dynamic Scoping in R Programming 5 min read Lexical Scoping in R Programming 4 min read Input/OutputTaking Input from User in R Programming 7 min read Printing Output of an R Program 4 min read Print the Argument to the Screen in R Programming - print() Function 2 min read Control FlowControl Statements in R Programming 4 min read Decision Making in R Programming - if, if-else, if-else-if ladder, nested if-else, and switch 3 min read Switch case in R 2 min read For loop in R 5 min read R - while loop 5 min read R - Repeat loop 2 min read goto statement in R Programming 2 min read Break and Next statements in R 3 min read FunctionsFunctions in R Programming 5 min read Function Arguments in R Programming 4 min read Types of Functions in R Programming 6 min read Recursive Functions in R Programming 4 min read Conversion Functions in R Programming 4 min read Data StructuresData Structures in R Programming 4 min read R Strings 6 min read R-Vectors 4 min read R-Lists 6 min read R - Array 7 min read R-Matrices 10 min read R-Factors 4 min read R-Data Frames 6 min read Object Oriented ProgrammingR-Object Oriented Programming 7 min read Classes in R Programming 3 min read R-Objects 3 min read Encapsulation in R Programming 3 min read Polymorphism in R Programming 6 min read R - Inheritance 7 min read Abstraction in R Programming 3 min read Looping over Objects in R Programming 5 min read S3 class in R Programming 8 min read Explicit Coercion in R Programming 3 min read Error HandlingHandling Errors in R Programming 3 min read Condition Handling in R Programming 5 min read Debugging in R Programming 3 min read File HandlingFile Handling in R Programming 3 min read Reading Files in R Programming 9 min read Writing to Files in R Programming 2 min read Working with Binary Files in R Programming 5 min read Like
