obtain sample attributes for a study.
samp_atts_by_study(srp = "SRP082656", size = 500, cursor = NULL, ...)
| srp | character(1) SRP tag for a study in NCBI SRA |
|---|---|
| size | numeric(1) maximum number of records to return |
| cursor | character(1) the value of the cursor returned in a previous call; see note. |
| ... | not currently used |
If the number of records available in query response exceeds the value of size, the
returned tibble will have an attribute 'cursor' which can be retrieved and used in
subsequent calls to this function.
If size is zero, a list is returned with information on the number of records available.
