getGeneInfo {homologene}

Download gene symbol information

Description

This function downloads the gene_info file from NCBI website and returns the gene symbols for current IDs.

Usage

getGeneInfo(destfile = NULL, justRead = FALSE, chunk_size = 1e+06)

Arguments

destfile

Path of the output file. If NULL a temp file will be used

justRead

If TRUE and destfile exists, it reads the file instead of downloading the latest one from NCBI

chunk_size

Chunk size to be used with link[readr]{read_tsv_chunked}. The gene_info file is big enough to make its intake difficult. If you don't have large amounts of free memory you may have to reduce this number to read the file in smaller chunks

Value

A data frame with gene symbols for each current gene id
