a SIFNX object (e.g. from the downloadPc2 function)
participantType
the type of participant on which the conversion will occur.
Important because not all ID types apply to all entities and otherwise those entities
would be labeled as missing an ID.
idType
an ID type for conversion (not used if mapping parameter used)
mapping
a two column data.frame with columns mapping$PARTICIPANT (old
IDs to convert from) and mapping$ID (new IDs to convert to)
naRm
remove edges where NA's were introduced due to failed conversions
Value
a SIFNX list with nodes and edges. Only edges will have converted IDs
