`mart`	object of class Mart created with the useMart function
`verbose`	Give detailed output of what the method is doing, for debugging purposes
`pattern`	Character vector defining the regular expression (`regex)` to be used for the search. If left blank the default is to use ".*" which will match everything and return the same as `listDatasets`.

if(interactive()){

    ## list the available Ensembl marts and use Ensembl Genes
    listEnsembl()
    ensembl <- useEnsembl(biomart = "ensembl")

    ## list the available datasets in this Mart
    listDatasets(mart = ensembl)

    ## the list of Ensembl datasets grows ever larger (101 as of Ensembl 93)
    ## we can search for a term of interest to reduce the length e.g. 'sapiens'
    searchDatasets(mart = ensembl, pattern = "sapiens")
    
    ## search for any dataset containing the word Rat or rat
    searchDatasets(mart = ensembl, pattern = "(R|r)at")
