Hello everyone!
In my ongoing odyssey through badly dokumented and sparingly commented
R-code, I've come across something that baffles me.
The following line of code
.Internal(filledcontour(as.double(x), as.double(y), z,
as.double(levels), col = col))
not surprisingly results in an error, telling me that there is no
such function as filledcontour().
But that passes a call to .Internal: it does not say what you say it
does. I suspect you saw
there is no .Internal function 'filledcontour'
which is quite a different matter.
The code this comes from has been written for an older version of R,
probably 2.5.x so I was wondering, if the error results from me using
a current version (3.1.0) or if the author wanted to use
filled.contour() and forgot the '.'.
Would that in fact help or was there something called filledcontour()
that has changed into something else nowadays?
It has. But it was never in the API, so should never have been used in
user code and was never documented in R itself.
You should be able to rewrite this using .filled.contour in package
graphics: it might be a drop-in replacement.
I've tried to contact the author, but he hasn't used R for at least
five years and hasn't replied so far, so I'm hoping soeone here can
give me a hint to the solution of this problem.
Many thanks in advance!
