Annotation tables within R

[shah-in-boots]

There are several issues with the conversion of annotations between the egm object and the underlying *.ann files from the WFDB.

1. Time is not appropriately recycled from the sample position
2. Default values are not available for type, subtype, or number

EGM::annotation_table("pks", sample = seq(1, 100, 11))
#> Error in `df_list()`:
#> ! Can't recycle `time` (size 0) to match `sample` (size 10).

To fix this, we likely need to do the following...

• [ ] Create a list of default values that would be safe if the data is missing from whatever baseline format
• [ ] Recycle length of vectors to create common sizes based on the sample size
• [ ] Create a format for time arguments that is the same between written files and the egm files
• [ ] Consider the need for including the start-time data from header into the time argument in the annotation table
