get_itemtable

A logical or character vector of item names to return. The
default (<code>NULL</code>) returns all items.

items

A <code>data.frame</code> set up according to the
same structure as <code><a rd-options="=builtin_itemtable" href="/link/builtin_itemtable()?package=dscore&version=1.0.0&to=%3Dbuiltin_itemtable" data-mini-rdoc="=builtin_itemtable::builtin_itemtable()">builtin_itemtable()</a></code>. If not specified,
the <code>builtin_itemtable</code> is used.

itemtable

The <code>builtin_itemtable</code> object in the <code>dscore</code> package
contains basic meta-information about items: a name, the equate group,
the instrument, the domain and the item label.
The <code>get_itemtable()</code> function returns a subset of <code>items</code>
in the itemtable.

The D-score is a quantitative measure of child development.
The D-score follows the Rasch model. See Jacobusse, van Buuren and
Verkerk (2006) <doi:10.1002/sim.2351>. The user can convert
milestone scores from 19 assessment instruments into the D-score
and the DAZ (D-score adjusted for age). Several tools assist in
mapping milestone names into the 9-position Global Scale of Early
Development (GSED) convention. Supports calculation of the D-score
using 'dutch' <doi:10.1177/0962280212473300>,
'gcdg' <doi:10.1136/bmjgh-2019-001724> and 'gsed' conversion keys.
The user can calculate DAZ using 'dutch' and 'gcdg' age-conditional
references.
