Hello,
I have a package with a namespace. Because I use Roxygen that overwrites the
NAMESPACE file each time it is run, I use a R/zzz.R file with
an .onLoad() and .onUnload() functions to take care of loading and unloading
my shared library.
The problem: if I load my library from a local directory, then the unloading
of the package fails, e.g:
# loads fine
>library(Foo, lib.loc=".Rcheck")
>unloadNamespace("Foo")
Warning message:
.onUnload failed in unloadNamespace() for 'Foo', details:
call: library.dynam.unload("Foo", libpath)
error: shared library 'Foo' was not loaded
# I traced it a little:
>library.dynam.unload("Foo", ".Rcheck/Foo")
Error in library.dynam.unload("Foo", ".Rcheck/Foo") :
shared library 'Foo' was not loaded
# using an absolute path works
>library.dynam.unload("Foo", "/home/toto/.Rcheck/Foo")
So from what I understand, the problem is either that the relative libpath
is sent to the .onUnload() function instead of the absolute one,
or that library.dynam.unload() should be modified to handle the relative
paths.
Am I missing something ? What should I do ?
Thanks,
Karl
