+#' @title PipeOpFilterRows
+#'
+#' @usage NULL
+#' @name mlr_pipeops_filterrows
+#' @format [`R6Class`] object inheriting from [`PipeOpTaskPreproc`]/[`PipeOp`].
+#'
+#' @description
+#' Filter rows of the data of a [`Task`][mlr3::Task].
+#'
+#' @section Construction:
+#' ```
+#' PipeOpFilterRows$new(id = "filterrows", param_vals = list())
+#' ```
+#'
+#' * `id` :: `character(1)` \cr
+#'   Identifier of resulting object, default `"filterrows"`.
+#' * `param_vals` :: named `list` \cr
+#'   List of hyperparameter settings, overwriting the hyperparameter settings that would otherwise
+#'   be set during construction. Default `list()`.
+#'
+#' @section Input and Output Channels:
+#' Input and output channels are inherited from [`PipeOpTaskPreproc`].
+#'
+#' The output is the input [`Task`][mlr3::Task] with rows kept according to the filtering expression.
+#' Whether filtering is performed during training and/or prediction can be specified via the `phase` parameter, see below.
+#'
+#' @section State:
+#' The `$state` is a named `list` with the `$state` elements inherited from [`PipeOpTaskPreproc`].
+#'
+#' @section Parameters:
+#' The parameters are the parameters inherited from [`PipeOpTaskPreproc`], as well as:
+#' * `filter_formula` :: `formula` | `NULL` \cr
+#'   Expression of the filtering to be performed, in the form of a `formula` that evaluates to `TRUE` or `FALSE`
+#'   for each row within the frame of the [`data.table`] [`DataBackend`][mlr3::DataBackend] of the [`Task`][mlr3::Task].
+#'   Rows for which the evaluation is `TRUE` are kept in the output [`Task`][mlr3::Task], others are removed.
+#'   Initialized to `NULL`, i.e., no filtering is performed and all rows are kept.
+#' * `SDcols` :: `function` | [`Selector`] \cr
+#'   [`Selector`] function, takes a [`Task`][mlr3::Task] as an argument and returns a `character` vector of features.
+#'   This character vector is set as the `.SDcols` argument when the formula above is evaluated within the frame of the
+#'   [`data.table`] [`DataBackend`][mlr3::DataBackend] of the [`Task`][mlr3::Task].
+#'   Initialized to [`selector_all()`], i.e., all features can be used as the `.SD` variable.
+#' * `phase` :: `character(1)` \cr
+#'   Character specifying the phase when filtering should be performed. Can either be `"always"`, `"train"`, or `"predict"`.
+#'   Initialized to `"always"`, i.e., filtering is performed both during training and prediction.
+#'
+#' @section Internals:
+#' A `formula` created using the `~` operator always contains a reference to the `environment` in which
+#' the `formula` is created. This makes it possible to use variables in the `~`-expressions that both
+#' reference either column names or variable names.
+#'
+#' @section Methods:
+#' Only methods inherited from [`PipeOpTaskPreproc`]/[`PipeOp`].
+#'
+#' @examples
+#' library("mlr3")
+#' task = tsk("pima")
+#' # filter based on some formula
+#' po = PipeOpFilterRows$new(param_vals = list(
+#'   filter_formula = ~ age < 31 & glucose > median(glucose, na.rm = TRUE))
+#' )
+#' po$train(list(task))
+#' # missing value removal for all features
+#' po$param_set$values$filter_formula = ~ !apply(is.na(.SD), MARGIN = 1L, FUN = any)
+#' po$train(list(task))
+#' # missing value removal only for some features
+#' po$param_set$values$SDcols = selector_name(c("mass", "pressure"))

+\format{
+\code{\link{R6Class}} object inheriting from \code{\link{PipeOpTaskPreproc}}/\code{\link{PipeOp}}.
+}
+\description{
+Filter rows of the data of a \code{\link[mlr3:Task]{Task}}.
+}
+\section{Construction}{
+\preformatted{PipeOpFilterRows$new(id = "filterrows", param_vals = list())
+}
+\itemize{
+\item \code{id} :: \code{character(1)} \cr
+Identifier of resulting object, default \code{"filterrows"}.
+\item \code{param_vals} :: named \code{list} \cr
+List of hyperparameter settings, overwriting the hyperparameter settings that would otherwise
+be set during construction. Default \code{list()}.
+}
+}
+
+\section{Input and Output Channels}{
+
+Input and output channels are inherited from \code{\link{PipeOpTaskPreproc}}.
+
+The output is the input \code{\link[mlr3:Task]{Task}} with rows kept according to the filtering expression.
+Whether filtering is performed during training and/or prediction can be specified via the \code{phase} parameter, see below.
+}
+
+\section{State}{
+
+The \verb{$state} is a named \code{list} with the \verb{$state} elements inherited from \code{\link{PipeOpTaskPreproc}}.
+}
+
+\section{Parameters}{
+
+The parameters are the parameters inherited from \code{\link{PipeOpTaskPreproc}}, as well as:
+\itemize{
+\item \code{filter_formula} :: \code{formula} | \code{NULL} \cr
+Expression of the filtering to be performed, in the form of a \code{formula} that evaluates to \code{TRUE} or \code{FALSE}
+for each row within the frame of the \code{\link{data.table}} \code{\link[mlr3:DataBackend]{DataBackend}} of the \code{\link[mlr3:Task]{Task}}.
+Rows for which the evaluation is \code{TRUE} are kept in the output \code{\link[mlr3:Task]{Task}}, others are removed.
+Initialized to \code{NULL}, i.e., no filtering is performed and all rows are kept.
+\item \code{SDcols} :: \code{function} | \code{\link{Selector}} \cr
+\code{\link{Selector}} function, takes a \code{\link[mlr3:Task]{Task}} as an argument and returns a \code{character} vector of features.
+This character vector is set as the \code{.SDcols} argument when the formula above is evaluated within the frame of the
+\code{\link{data.table}} \code{\link[mlr3:DataBackend]{DataBackend}} of the \code{\link[mlr3:Task]{Task}}.
+Initialized to \code{\link[=selector_all]{selector_all()}}, i.e., all features can be used as the \code{.SD} variable.
+\item \code{phase} :: \code{character(1)} \cr
+Character specifying the phase when filtering should be performed. Can either be \code{"always"}, \code{"train"}, or \code{"predict"}.
+Initialized to \code{"always"}, i.e., filtering is performed both during training and prediction.
+}
+}
+
+\section{Internals}{
+
+A \code{formula} created using the \code{~} operator always contains a reference to the \code{environment} in which
+the \code{formula} is created. This makes it possible to use variables in the \code{~}-expressions that both
+reference either column names or variable names.
+}
+
+\section{Methods}{
+
+Only methods inherited from \code{\link{PipeOpTaskPreproc}}/\code{\link{PipeOp}}.
