what is the preferred method to create a package local variable?
for the moment, I'm using:
.onAttach <- function(libname, pkgname) {
.bbg.db.conn <<- dbConnect(dbDriver("PostgreSQL"), user="blah","blah")
}
.onUnload <- function(libpath) {
dbDisconnect(.bbg.db.conn)
}
which results in a hidden global variable in the global environment.
I would prefer to make the assignment only in the package namespace.
