thin | R Documentation |
This function can be used to remove ('thin') data from
epicontacts
objects to ensure stricter matching of linelists
and contacts. It has two behaviours, triggered by the argument what
:
either it thins data from $linelist
, keeping only cases that are in
$contacts
(thin = "linelist"
, default), or the converse,
i.e. removing contacts which are not fully documented in the linelist.

A character string or integer determining which type of data is
removed ('thinned'). "linelist" / 1 indicates that only cases appearing
