Is there a way to set default parameter values using DML? I believe both R and Python offer this capability.
The only solution I could come up with using DML is to pass in a variable that is NaN and cast this to a string and use this string in an if conditional statement. addone = function(double b) return (double a) { c = ''+b; if (c == 'NaN') { b = 2.0 } a = b + 1; } z=0.0/0.0; x = addone(z); print(x); y = addone(4.0); print(y); Is there a cleaner way to accomplish this, or is DML lacking this R feature?
