as.data.frame as well as the myObject[] syntax which makes a lot of sense. I'd
also like to implement an as.double() method. However, I'm having trouble
embedding this into my package. In the R file I have:
CJ> setMethod("as.double", "HD5Proxy", function(x) as.double(x[]))
CJ> and exportMethods(as.double) in my NAMESPACES file. However, on
checking the package, I get an error saying that method "as.double" cannot be
found. I noticed that the setMethod command actually returns a character
vector with "as.numeric", so I'm assuming this is the problem. How do I
explicitly export my as.double method?
As you've noticed above, `` R prefers as.numeric ''
and that is what you should be dealing with instead :
It's unsatisfactory I agree, but that's what it currently is:
setMethod("as.numeric", ....
and exportMethods(as.numeric)
