Replace the Elements of a Vector in R Programming – replace() Function
replace() function in R Language is used to replace the values in the specified string vector x with indices given in list by those given in values.
Syntax: replace(x, list, values)
Parameters:
x: vector
list: indices
values: replacement values
Example 1:
# R program to illustrate # replace function # Initializing a string vector x <- c("GFG", "gfg", "Beginner") # Getting the strings x # Calling replace() function to replace # the word gfg at index 2 with the # w3wiki element y <- replace(x, 2, "w3wiki") # Getting the new replaced strings y |
Output :
[1] "GFG" "gfg" "Beginner" [1] "GFG" "w3wiki" "Beginner"
Example 2:
# R program to illustrate # replace function # Initializing a string vector x <- c("GFG", "gfg", "Beginner") # Getting the strings x # Calling replace() function to replace # the word GFG at index 1 and Beginner 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" "Beginner" [1] "A" "gfg" "B"
