as.vf

as.vf,function-method

as.vf,ANY-method

Coerce objects to a virtual function. Numeric or complex arguments
 are coerced to a constant function.

If f <- function(x){x^2} and g <- function(x){x+1} it is
a constant source of annoyance that "f+g" is not defined.
Package 'vfunc' allows you to do this, and we have (f+g)(2)
returning 5. The other arithmetic operators are similarly
implemented. A wide class of coding bugs is eliminated.
