Get the number of metadata files in a study.
num_meta_files(study_view, num_docs = NULL)
| study_view | The file view for the study files. At minimum, the study_view is a dataframe or tibble with `metadataType` as a column name. Any `NA` in this column is assumed to be documentation files, all others are assumed to be metadata files. |
|---|---|
| num_docs | Number of document files that are in the `study_view`. If `NULL`, will call `num_doc_files()` to get the value. This is here in case that the number of document files is known already. |
The number of metadata files present in the `study_view`.
