pipeCPO

[<code>list</code> of <code>CPO</code> | <code>list</code> of <code>CPOTrained</code>]
A list of <code><a rd-options="" href="/link/CPO?package=mlrCPO&version=0.3.4-4" data-mini-rdoc="mlrCPO::CPO">CPO</a></code> or <code><a rd-options="" href="/link/CPOTrained?package=mlrCPO&version=0.3.4-4" data-mini-rdoc="mlrCPO::CPOTrained">CPOTrained</a></code> objects.

pplist

Chain a list of preprocessing operators, or retrafo objects, turning <code>list(a, b, c)</code> into
<code>a %&gt;&gt;% b %&gt;&gt;% c</code>.
This is the inverse of <code><a rd-options="" href="/link/as.list.CPO?package=mlrCPO&version=0.3.4-4" data-mini-rdoc="mlrCPO::as.list.CPO">as.list.CPO</a></code> / <code><a rd-options="" href="/link/as.list.CPOTrained?package=mlrCPO&version=0.3.4-4" data-mini-rdoc="mlrCPO::as.list.CPOTrained">as.list.CPOTrained</a></code> when applied to <code><a rd-options="" href="/link/CPO?package=mlrCPO&version=0.3.4-4" data-mini-rdoc="mlrCPO::CPO">CPO</a></code> or <code><a rd-options="" href="/link/CPOTrained?package=mlrCPO&version=0.3.4-4" data-mini-rdoc="mlrCPO::CPOTrained">CPOTrained</a></code>.

Toolset that enriches 'mlr' with a diverse set of preprocessing
operators. Composable Preprocessing Operators ("CPO"s) are first-class
R objects that can be applied to data.frames and 'mlr' "Task"s to modify
data, can be attached to 'mlr' "Learner"s to add preprocessing to machine
learning algorithms, and can be composed to form preprocessing pipelines.

pipeCPO function

[<code>list</code> of <code>CPO</code> | <code>list</code> of <code>CPOTrained</code>]
A list of <code><a rd-options='' href='CPO'>CPO</a></code> or <code><a rd-options='' href='CPOTrained'>CPOTrained</a></code> objects.

Chain a list of preprocessing operators, or retrafo objects, turning <code>list(a, b, c)</code> into
<code>a %&gt;&gt;% b %&gt;&gt;% c</code>.
This is the inverse of <code><a rd-options='' href='as.list.CPO'>as.list.CPO</a></code> / <code><a rd-options='' href='as.list.CPOTrained'>as.list.CPOTrained</a></code> when applied to <code><a rd-options='' href='CPO'>CPO</a></code> or <code><a rd-options='' href='CPOTrained'>CPOTrained</a></code>.
