| Title: | eds: Low-level reader for Alevin EDS format |
|---|---|
| Description: | This packages provides a single function, readEDS. This is a low-level utility for reading in Alevin EDS format into R. This function is not designed for end-users but instead the package is predominantly for simplifying package dependency graph for other Bioconductor packages. |

This provides a simple utility for reading in EDS format. Note that most users will prefer to use tximport or tximeta. This function and package exist in order to simplify the dependency graph for other packages.
