Description Usage Arguments Note

Description

retrieve a normalized data.frame of sample attributes for SRAdbV2 study tibbles

Usage

1
sampleAtts(studyAcc, returnBad = FALSE, forcedTags = NULL)

Arguments

studyAcc

character(1) accession

returnBad

logical(1) returns tibble of experiment metadata for which number of fields in sample.attributes is less than the number in the majority

forcedTags

NULL or character(), introduced to cope with studies for which SRA metadata has inconsistent field sets across experiments. Supply a vector of tags that need to be retrieved; when the metadata lacks a value for the tag it is filled with NA.

Note

Sometimes a field is omitted for control experiments, and with manual programming conformant metadata can be produced for these experiments. Sometimes there is substantial diversity among sample.attribute fields recorded within a study.
