getVariantsPage {GoogleGenomics} | R Documentation |
In general, use the getVariants method instead. It calls this method, returning variants from all of the pages that comprise the requested genomic range.
getVariantsPage(variantSetId = "10473108253681171589", chromosome = "22", start = 16051400, end = 16051500, fields = NULL, pageToken = NULL)
variantSetId |
The dataset ID. |
chromosome |
The chromosome. |
start |
Start position on the chromosome in 0-based coordinates. |
end |
End position on the chromosome in 0-based coordinates. |
fields |
A subset of fields to retrieve. The default (NULL) will return all fields. |
pageToken |
The page token. This can be NULL (default) for the first page. |
By default, this function gets variants from a small section of 1000 Genomes phase 1 variants.
A two-element list is returned by the function.
variants: A list of R objects corresponding to the JSON objects returned by the Google Genomics Variants API.
nextPageToken: The token to be used to retrieve the next page of results, if applicable.
