Yes, but since I am working on Linux, it is slightly more steps

Hello,

Error in isOpen(con) : invalid connection
Is it expected ?
Tested on R
Hi Karl,
that is expected. The moment you close a connection, it is destroyed as
well (see ?close). A destroyed connection cannot be tested. In fact, I've
used isOpen() only in combination with the argument rw.

On Thu,
Thanks Joris, it makes sense now, though the doc is a bit misleading.

When you provide a method for a generic function imported from another
package then the generic must be on the search path. Otherwise if a user
types "filter" the dispatch to "filter.test" will never occur.
What is happening here is worse because "filter" is a non-generic
function in the stats pac
Oh, I forgot to mention I tried a few other variations:
=
Re-export dplyr::filter:
filter <- dplyr::filter
NAMESPACE has:
S3method(filter,test)
export(filter)
importFrom(dplyr,filter)
Then the filter.test method from s3methodtest doesn't seem to get
registered properly:
Export filter in the NAMESPACE file *without copying it* in the R source code.

Is there some way to reset or restart the JVM within the fork?

Ah, it works! Thank you!

but note that you will have to document it even if it is a function
imported from another package... Perhaps help() should be intelligent
enough to link the documentation of `FUN` from package A for package B
when B imports `FUN` from A, and exports it in B's NAMESPACE. The
package name of A may be
