[R] Rare behaviour for nlme::reStruct example and question about ?lmeObject

[Iago]

Dear Bert and all other "helpers",


I agree that not all of you are developers. If I look at the DESCRIPTION 
of the nlme package I can see the next:

    Contact: see 'MailingList'

    BugReports: https://bugs.r-project.org
    MailingList: R-help using r-project.org

    Maintainer: R Core Team <R-core using R-project.org>

As I do not have bugs.r-project account, first I emailed to 
R-core using R-project.org, from where I got the next answer

    "Non-members are typically*NOT*  allowed to post messages to this
    private developers' list. Please use an appropriate mailing list (from
    http://www.r-project.org/mail.html). For R packages, use
    maintainer("<pkg>") in R (and if that is R-core using .., use the R-help
    address).

    --> i.e. for nlme  use  R-help

by Martin Maechler. Therefore, I used R-help.

Best,

Iago
