Extract the data underlying an S3 vector object, i.e. the underlying atomic vector or list. Currently, due to the underlying memory architecture of R, this creates a full copy of the underlying data.
vec_data(x)A vector
The data underlying x, free from an attributes.
See vec_restore() for the inverse operation: it restores
attributes given a bare vector and a prototype;
vec_restore(vec_data(x), x) will always yield x.
