[R-pkg-devel] "invalid 'envir' argument" note from R-devel

Dear Duncan and Peter,

I've just arrived at more or less the same thing:

	foo <- function() data(package="MASS")

	bar <- function() data(package="MASS", envir=.GlobalEnv)

	baz <- function() data(package="MASS", envir=globalenv())

all trigger the note when included with the Rcmdr sources:

	* checking R code for possible problems ... NOTE
	bar: Error while checking: invalid 'envir' argument
	baz: Error while checking: invalid 'envir' argument
	foo: Error while checking: invalid 'envir' argument 

The envir argument to data() defaults to .GlobaEnv .

I hope this helps,
 John
