Compare two strings partially using grepl()

Concepts Related to the Topic :

String Comparison: Comparison of two strings and check whether they are equal or not. Equality Operators (==): It is used to compare two string for equality and inequality. Case Sensitivity: In R language programming strings are considers as case-sensitive by default. There are functions like tolower() or toupper() to make case-insensitive comparison. tolower(): tolower() is the function to convert the string to lower case. toupper(): toupper() is the function to convert string to upper case. identical(): indentical() is function to compare two string and true or false according to the input string. grepl(): grepl() is function to compare two string partially....

Strings

A collection of character variables make up a string. There is only one dimension to the cast of characters. In R, a string is defined as one or more letters surrounded in a pair of matching single or double quotes. In R programming, strings are used to represent textual material and can include special characters, digits, and spaces. ” is used to denote an empty string. R Strings are always kept in double-quoted form in storage. Single quotes may appear inside of a double-quoted string. Single quotes are not permitted in single-quoted strings. In a similar vein, double quotations cannot be enclosed in double quotes....

Steps Needed :

Define the two strings you want to compare. Use a comparison operator (== or !=) to compare the strings. Use functions like tolower() or toupper() for case-insensitive comparisons. Use grepl() for partial comparision. Use identical() for string comparision. Use if condition and print the result....
