plyxp provides efficient abstractions to the SummarizedExperiment such that using common dplyr functions feels as natural to operating on a data.frame or tibble. plyxp was built as an alternative to the tidySummarizedExperiment package but there may be a future in which their conflicts are reconciled. plyxp uses data-masking from the rlang package in order to connect dplyr functions to SummarizedExperiment slots in a manner that aims to be intuitive and avoiding ambiguity in outcomes.
Note: This package is still under active development as of Fall 2024.
installing plyxp
BiocManager::install("plyxp")data masking SummarizedExperiment
The SummarizedExperiment object contains three main components/“contexts” that we mask, the assays(), rowData()1 and colData().
plyxp provides variables as-is to data within their current contexts enabling you to call S4 methods on S4 objects with dplyr verbs. If you require access to variables outside the context, you may use pronouns made available through plyxp to specify where to find those variables.

The .assays, .rows and .cols pronouns outputs depends on the evaluating context. Users should expect that the underlying data returned from .rows or .cols pronouns in the assays context is a vector, replicated to match size of the assay context.
Alternatively, using a pronoun in either the rows() or cols() contexts will likely return a list equal in length to either nrows(rowData()) or nrows(colData()).
