Usage

getBioMartData(genes,verbose=FALSE,...)

Arguments

genes

A vector of gene names matching hgnc_symbol in the Ensembl database.

verbose

A Boolean indicating whether to output the funcitons progress in terms of the dimensions of the data.frame being constructed. Default is FALSE.

...

Additional arguments passed on to the internal call to biomaRt::useMart(...). If no such arguments are provided, useMart("ensembl", dataset="hsapiens_gene_ensembl") is run by default.

Value

A data.frame object with columns 'gene','chr','start', and 'end', suitable for input to the setGeneTable function.
