hi,
my apologies if this has been covered numerous times before and it's
only my lack of search and/or R skills that is stopping me from
finding the solution.
i'm trying to access an object defined and created inside a function
(the object is not returned by the function), but i can't seem to get
it to work, i keep getting an "object not found" error message. i
thought the solution where to be found in changing the
frame/environment. but i can't seem to understand how do do it
correctly. what i want to do is something like:
my.function() <- {
function.from.package(x,y)
plot (object.inside.package.function)
}
That pseudo-code doesn't really make sense: you didn't save the result
of function.from.package() anywhere. If you change it to
my.function() <- {
z <- function.from.package(x,y)
plot (z)
}
then it's perfectly standard. So the question is: where are you
expecting R to look to find object.inside.package.function?
I suspect the OP doesn't care where R looks as
long as it finds it. The fact that everything about
'function.from.package' except 'z' has been sucked
down a black hole by the time 'plot' is on the scene
is going to make that search impossible.
One solution is to create 'my.function.from.package'
and change the return value to include
'object.inside.package.function'.
