## R CMD check results
There were no ERRORs or WARNINGs

    loomR, SDMTools
  Availability using Additional_repositories specification:
    loomR      yes   https://mojaveazure.github.io/loomR

  One of the packages we suggest, loomR, is currently under development and not yet available on CRAN. This package is not required for core functionality of Seurat. The other package, SDMTools is also not required for core functionality. We are working to replace the function that calls SDMTools with a new function using non-orphaned packages

* checking package dependencies ... NOTE
  Package suggested but not available for checking: 'loomR'

  Suggests orphaned package: ‘SDMTools’

  loomR is a suggested package hosted on a custom repository and maintained by us (both the package and repository).

  SDMTools is not required for any essential functionality. We are working to replace the function that calls SDMTools with a new function using non-orphaned packages.

* checking Rd cross-references ... NOTE

  This is a suggested package that we maintain. We have checked the cross references to ensure they link to the correct help pages.
