Usage

NCBI dbSNP data

snps <- c("rs332", "rs420358", "rs1837253", "rs1209415715", "rs111068718")
ncbi_snp_query(snps)

The ncbi_snp_query() function can be used with an NCBI API which gives access higher numbers of API requests per second. More information about setting this up can be found in the package help accessed via ?rsnps.
