[Rd] In the documentation of 'Ops.Date', please remove mention about "difftime", like in the documentation of 'DateTimeClasses' (PR#14072)
I am sorry to reply. But I need to clarify things.=0A=0AFrom searching over the
internet, I know that, before R 2.5.0, in the documentation of
'DateTimeClasses', in 'date + x', in the explanation about
'x', there is also mention that 'x' can be a 'difftime'
object. Now, it has been removed.=0A=0AWhy not doing the same in the
documentation of 'Ops.Date'? I have read the documentation carefully.
Also, I have just downloaded
http://cran.bic.nus.edu.sg/src/base-prerelease/R-latest.tar.gz. In the file
Ops.Date.Rd, the phrase=0A\emph{or} an object of class=0A
\code{"\link{difftime}"}=0Ais still there. This is a snapshot from
Ops.Date.Rd.=0A=0A\usage{=0A\special{date + x}=0A\special{date -
x}=0A\special{date1 lop date2}=0A}=0A\arguments{=0A \item{date}{date

\item{x}{a numeric vector (in days) \emph{or} an object of class=0A
\code{"\link{difftime}"}.}=0A \item{lop}{One of \code{=3D=3D},
\code{!=3D}, \code{<}, \code{<=3D}, \code{>}=0A or
\code{>=3D}.}=0A}=0A=0AThe documentation says that the usage is=0Adate +
x=0ASo,=0Adate + x=0Ashould work.=0A=0ASo, in the documentation of
'Ops.Date', in the explanation about argument 'x', please remove
the phrase "or an object of class "difftime".". That would
be in line with the documentation of 'DateTimeClasses', and at least
saves new users.=0A=0AThank you.=0A=0A=0A New Email addresses available on
