[R-pkg-devel] no visible binding for '<<-' assignment note

[Richard M. Heiberger]

I would guess that your NAMESPACE file doesn't export dnormfun.

If I don't use the super assignment  "<<-"  then the kronecker function cannot find "dnormfun" function. The question now seems that how I can let the kronecker(X, Y, FUN = "*",...) know that "dnormfun" is a "FUN"?

Is this really what you want to do, define a function "dnormfun" that is available in the user's global environment? If yes, then you'll need to make a case for it in your CRAN submision comments. If no, then you can probably just change "<<-" to "<-".
