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.
That's not legal syntax, so I'm not sure why you think it is accepted by
R. I see this when I try to run that:
> data("WingPoints",envir = environment(()))
Error: unexpected ')' in "data("WingPoints",envir = environment(()"
What Sweave apparently objects to is the first closing
inner bracket, indicating an empty inner argument for
the variable environment.
No, since it is not legal syntax, it doesn't indicate anything at all.
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
It's a bug in your code. I don't know if this is what you are trying to
do, but this would be legal syntax:
data("WingPoints",envir = environment())
