Print character strings without quotes.

any R object, typically a vector of

noquote returns its argument as an object of class
"noquote". There is a method for c() and subscript
method ("[.noquote") which ensures that the class is not lost
by subsetting. The print method (print.noquote) prints
character strings without quotes ("\dots").
If right is specified in a call print(x, right=*), it
takes precedence over a possible right setting of x,
e.g., created by x <- noquote(*, right=TRUE).
These functions exist both as utilities and as an example of using (S3)
class and object orientation.
