Creation of String in R
R Strings can be created by assigning character values to a variable. These strings can be further concatenated by using various functions and methods to form a big string.
Example
R
# R program for String Creation# creating a string with double quotesstr1 <- "OK1"cat ("String 1 is : ", str1)# creating a string with single quotesstr2 <- 'OK2'cat ("String 2 is : ", str2)str3 <- "This is 'acceptable and 'allowed' in R"cat ("String 3 is : ", str3)str4 <- 'Hi, Wondering "if this "works"'cat ("String 4 is : ", str4)str5 <- 'hi, ' this is not allowed'cat ("String 5 is : ", str5) |
Output
String 1 is: OK1 String 2 is: OK2 String 3 is: This is 'acceptable and 'allowed' in R String 4 is: Hi, Wondering "if this "works" Error: unexpected symbol in " str5 <- 'hi, ' this" Execution halted
R Strings
Strings are a bunch of character variables. It is a one-dimensional array of characters. One or more characters enclosed in a pair of matching single or double quotes can be considered a string in R. Strings in R Programming represent textual content and can contain numbers, spaces, and special characters. An empty string is represented by using “. R Strings are always stored as double-quoted values. A double-quoted string can contain single quotes within it. Single-quoted strings can’t contain single quotes. Similarly, double quotes can’t be surrounded by double quotes.
