seq_len0

seq_along0

:: <code>any</code>
Arbitrary object. Used to query its rows, cols or length.

:: <code>integer(1)</code>
Length of the sequence.

<code>seq_row()</code> creates a sequence along the number of rows of <code>x</code>,
<code>seq_col()</code> a sequence along the number of columns of <code>x</code>.
<code>seq_len0()</code> and <code>seq_along0()</code> are the 0-based counterparts to <code><a rd-options="base:seq_len" href="/link/base%3A%3Aseq_len()?package=mlr3misc&version=0.1.0&to=base%3Aseq_len" data-mini-rdoc="base:seq_len::base::seq_len()">base::seq_len()</a></code> and
<code><a rd-options="base:seq_along" href="/link/base%3A%3Aseq_along()?package=mlr3misc&version=0.1.0&to=base%3Aseq_along" data-mini-rdoc="base:seq_along::base::seq_along()">base::seq_along()</a></code>.

Frequently used helper functions and assertions
used in 'mlr3' and its companion packages. Comes with helper functions
for functional programming, for printing, to work with 'data.table',
as well as some generally useful 'R6' classes. This package also
supersedes the package 'BBmisc'.
