Summary table of the R packages and tool (*) that address some of the issues identified in the scoping review.

The ticks (✓) indicate whether an R package includes that modification type and rows that are grey show the modification types that have not been incorporated into a known R package or tool. The final three rows summarise additional exploration by the authors to assess how easily each package/tool can be installed and used. For full details of how each classification (very good = ✓✓, good = ✓, poor = ✗) was defined, see Table B in S1 Text and the associated text (section 3).
