noquote(obj) ## S3 method for class 'noquote': print(x, ...) ## S3 method for class 'noquote': c(..., recursive = FALSE)
obj |
any R object, typically a vector of
character strings. |
x |
an object of class "noquote" . |
... |
further options passed to next methods, such as print . |
recursive |
for compatibility with the generic c function. |
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 ("..."
).
These functions exist both as utilities and as an example of using (S3)
class
and object orientation.
