Get the position of a chain entry (track or rez) in a chain (trail or resonance).

Usage

getPosInChain(
  tokenOrder = NULL,
  chain = NULL,
  exclFrag = F,
  combinedChunk = NULL,
  nonFragmentMember = F
)

tokenOrder: The vector of sequence values values where the mentions appeared. Common choices are docTokenSeqFirst, docTokenSeqLast, wordTokenSeqFirst and wordTokenseqLast (the last two are available after running addIsWordField on a rezrObj. By default it's docTokenSeqLast.
chain: The chain that each mention belongs to.
exclFrag: Exclude 'fragments' (i.e. members of a combined chunk which do not serve as meaningful chunks in their own right)
combinedChunk: The combinedChunk column of the rezrDF. By default, named combinedChunk.
nonFragmentMember: Vector indicating whether each entry is a non-fragment member, i.e. a member of a combined chunk that also serves as a meaningful chunk in its own right.
