| Title: | A Simple S3 Class for Representing Vectors of Binary Data ('BLOBS') |
|---|---|
| Description: | R's raw vector is useful for storing a single binary object. What if you want to put a vector of them in a data frame? The 'blob' package provides the blob object, a list of raw vectors, suitable for use as a column in data frame. |

new_blob() is a low-level constructor that takes a list of
raw vectors.
blob() constructs a blob from individual raw vectors.
as_blob() and is_blob() are simple forwarders to vctrs::vec_cast()
and inherits(), respectively.
