Hello,

When I try to check my package, I have this error :

* installing *source* package ‘mypackage’ ...
** using staged installation
** R
** inst
** byte-compile and prepare package for lazy loading
Error: object ‘parallel_slot_names’ is not exported by 'namespace:S4Vectors'
Execution halted
ERROR: lazy loading failed for package ‘mypackage’

I don't call parallel_slot_names in my package. What can I do ?

Thank you in advance for help.

You could check to make sure you have all updated versions of packages with BiocManager::valid() or BiocManager::install() .

It could be a package you depend on has not properly adjusted their package to remove parallel_slot_names which was removed from S4Vectors after being deprecated. Or they might have already adjusted and you might not have the most recent version of a dependent package.

    Remove parallelSlotNames()

    Was deprecated in BioC 3.11 and defunct in BioC 3.12.

Note that parallel_slot_names is the new name for parallelSlotNames. The latter got removed but not the former.

Thanks for the correction. So yes ilysR, I would try updating all package and making sure you have a valid install.

parallel_slot_names() was added in BioC 3.12 which is the current release so most likely you're using an outdated version of Bioconductor. Note that it would be easier for us to help you if you were showing your sessionInfo() as instructed in our Posting Guide. Thanks!
