dplyr_extensions: Extending 'dplyr' for 'tm' class

In asshah4/octomod: A Causality-Informed Modeling Approach

Extending dplyr for tm class

Description

The filter() function extension subsets tm that satisfy set conditions. To be retained, the tm object must produce a value of TRUE for all conditions. Note that when a condition evaluates to NA, the row will be dropped, unlike base subsetting with [.

Usage

## S3 method for class 'tm'
filter(.data, ...)

Arguments

.data	A data frame, data frame extension (e.g. a tibble), or a lazy data frame (e.g. from dbplyr or dtplyr). See Methods, below, for more details.
...	<data-masking> Expressions that return a logical value, and are defined in terms of the variables in .data. If multiple expressions are included, they are combined with the & operator. Only rows for which all conditions evaluate to TRUE are kept.

Value

An object of the same type as .data. The output as the following properties:

• tm objects are a subset of the input, but appear in the same order

• Underlying data.frame columns are not modified

• Underlying data.frame object's attributes are preserved
