Strings:

In script write commands:

#writing the strings in R language
myname <- "your name"
print (myname)

Output:
[1] "your name"

Explanation:
In the first line # is defining the comment. R supports only the single line comment.

Here myname is a variable which stores the the string literal "your name"
and when a print command issued on the myname then it prints the string literal.

Here you can use single quotes or double quotes . the output will be same:

myname <- 'your name'
print(myname)

Output:
[1] "your name"

Explanation:
In the output the string literal will be in the double quotes in the two cases.

--------------------------------------------------------------------------------------------------------------------------

Assigning the value for vectortwo

> print(vectortwo)
printing the value of the variable

Output
[1] "your name"

printing the class of the variable

Output
> print(class(vectortwo))
[1] "character"
