head.dataset

tail.dataset

Returns the first or last parts of a dataset.
Both head() and tail() are generic functions.

The aim of the 'dataset' package is to make tidy datasets easier to release,
exchange and reuse. It organizes and formats data frame 'R' objects into well-referenced,
well-described, interoperable datasets into release and reuse ready form. A subjective
interpretation of the W3C DataSet recommendation and the datacube model <https://www.w3.org/TR/vocab-data-cube/>,
which is also used in the global Statistical Data and Metadata eXchange standards,
the application of the connected Dublin Core <https://www.dublincore.org/specifications/dublin-core/dcmi-terms/>
and DataCite <https://support.datacite.org/docs/datacite-metadata-schema-44/> standards
preferred by European open science repositories to improve the findability, accessibility,
interoperability and reusability of the datasets.

head.dataset function

<dl><dt>x</dt>
<dd>A dataset object created with dataset.</dd>
<dt>n</dt>
<dd>an integer vector of length up to <code>dim(x)</code>
(or 1, for non-dimensioned objects). A <code>logical</code> is silently coerced to
integer. Values specify the indices to be selected in the corresponding
dimension (or along the length) of the object. A positive value of <code>n[i]</code>
includes the first/last <code>n[i]</code> indices in that dimension,
while a negative value excludes the last/first
<code>abs(n[i])</code>, including all remaining indices.
<code>NA</code> or non-specified values (when <code>length(n) &lt; length(dim(x))</code>) select all
indices in that dimension. Must contain at least one non-missing value.</dd>
<dt>...</dt>
<dd>Ignored.</dd>
<dt>keepnums</dt>
<dd>in each dimension, if no names in that dimension are present,
create them using the indices included in that dimension.
Ignored if <code>dim(x)</code> is <code>NULL</code> or its length 1.</dd></dl>
