Common Issues

1. Package issue tracking

1.1 Package issues

• haven::read_xpt() Some attributes are dropped after using haven::write_xpt() haven::read_xpt(), e.g., type, length. to do: further check

• xportr::xportr_length() NA_character_ is considered as length 2 - issue resolved on Dec 14, 2022 to do: to be incorporated in pilot3

1.2 Potential improvement

• metatools::build_from_derived() https://github.com/pharmaverse/metatools/issues/46 Not urgent feature but nice to have - especially when define.xml is not in good quality

2. Knowledge sharing
