Dear all, in one of my packages I need to load some data from .Rdata files that are to be used from some functions (but not all off them). I would like to delay the loading of this datasets only when needed. In other cases I successfully used lazyLoad and delayedAssign(), but when I try to load a .Rdata file I get this message: Error: cannot add bindings to a locked environment What would be the best way to load such a db only the first time that is needed? Thanks a lot for you help, Cheers, Luca
