comment: Query or Set a "comment" Attribute

Description

These functions set and query a comment attribute for any R objects. This is typically useful for data.frames or model fits.

Contrary to other attributes, the comment is not printed (by print or print.default).

Assigning NULL or a zero-length character vector removes the comment.

Usage

comment(x)
comment(x) <- value

Arguments

x

any R object

value

a character vector, or NULL.

                "Jun 5, 1998")
