Parse data from requests to VecDyn — glean

Extract the data returned by a call to fetch_vd(), filter columns of interest, and find unique rows if required.

Usage

glean_vd(res, cols = NA, returnunique = FALSE)

Arguments

res: a list of responses from VecDyn as an ohvbd.responses object.
cols: a character vector of columns to extract from the dataset. If specified, this will be adjusted to always include the "dataset_id" column.
returnunique: whether to return only the unique rows within each dataset according to the filtered columns.

Value

An ohvbd.data.frame containing the requested data.
