Example 1:
Python3 1==
# R program to illustrate
# the use of gsub() function
# Create a string
x <- "Geeksforgeeks"
# Calling gsub() function
gsub("eek", "ood", x)
# Calling gsub() with case-sensitivity
gsub("gee", "Boo", x, ignore.case = FALSE)
# Calling gsub() with case-insensitivity
gsub("gee", "Boo", x, ignore.case = TRUE)
Output:
[1] "Goodsforgoods"
[1] "GeeksforBooks"
[1] "BooksforBooks"
Example 2:
Python3 1==
# R program to illustrate
# the use of gsub() function
# Create a string
x <- c("R Example", "Java example", "Go-Lang Example")
# Calling gsub() function
gsub("Example", "Tutorial", x)
# Calling gsub() with case-insensitivity
gsub("Example", "Tutorial", x, ignore.case = TRUE)
Output:
[1] "R Tutorial" "Java example" "Go-Lang Tutorial"
[1] "R Tutorial" "Java Tutorial" "Go-Lang Tutorial"
