I am using Sweave to create a vignette for a package,
but when it appears in a code chunk of the .Rnw file
the following line causes an execution halt of Sweave:-
data("WingPoints",envir = environment(()))
This is surprising since this data call as a line
of a function within the package is accepted by R
and is indeed part of the "Best practice" recommendations
in ?data called from R.
What Sweave apparently objects to is the first closing
inner bracket, indicating an empty inner argument for
the variable environment.
Is this a bug or what should I do? The function runs perfectly
in R in its usual context, and in the .Rnw file it is in a chunk
headed
<<eval=FALSE>=
