I'm using SRAdb to download the SRA files from Accession SRP002480. This is quite a large set of files, but I'm only interested in downloading the files for body site = "human skin". In the RunInfo Table, it is coded as "body_site_s" = "human skin". How can I extract only those files?

library(SRAdb)
library(DBI)

srafile = getSRAdbFile()

con = dbConnect(RSQLite::SQLite(), srafile)

getSRAfile('SRP002480',con,fileType='sra')
