[Rd] new warnings related to the extractor "$" with R 2.5.0alpha
Dear all, I just installed R 2.5.0alpha and noticed new warnings related to the extractor "$" when using contributed packages. For instance: > library(RODBC) Warning message: $ operator is not valid for atomic vectors, returning NULL > library(aod) Package aod, version 1.1-18 > data(orob2) > m1 <- betabin(cbind(y, n-y) ~ 1, random = ~ 1, data = orob2) > head(residuals(m1)) 1 2 3 4 5 6 -1.4629774 -0.7897877 -1.3754283 0.1029910 -0.3556985 1.4030026 Warning message: $ operator not defined for this S4 class, returning NULL In these two cases, I deleted the former installations and re-built the packages from sources. How to overcome this problem ?

Wait for package updates. For RODBC, it is harmless but the warning will not appear in 1.1-9 (which will be released before R 2.5.0 is). (The first message is not really right: $ for lists was valid and documented to return NULL in released versions of R, as it was in the Blue Book. It should say that it is 'deprecated' in R 2.5.0, since this amounts to a change of language definition and that should be giving a warning of deprecation.) Later versions of R 2.5.0 alpha give more informative messages. -- Brian D.

Re: [Rd] new warnings related to the extractor "$" with R 2.5.0alpha
Thank you for this explanation. As the package maintainer for aod (second warning message), I found where the warning came from and will post an update soon.

As you most probably found out for yourself - this works
as intended.

[1] TRUE

[Rd] Non-unique column names in data frames
Dear r-devel members,
It's just been brought to my attention that R permits non-unique column
names in data frames -- e.g., via assignment to names() or colnames(). This
behaviour is consistent with the help files (as I discovered), but it's not
consistent with the behaviour of rownames() and row.names(). For example,
row.names(airquality) <- rep("a", nrow(airquality))
generates an error, but
names(airquality) <- rep("a", ncol(airquality))
or even
names(airquality) <- rep("", ncol(airquality))
do not.
I figure that there must be some rationale for this difference, but I can't
think of what it might be. Any thoughts?
Regards,
John
