fetchBMdata: Retrieve data from Budowle and Moretti (1999) from the web

Description

Retreives the Budowle and Moretti (1999) and compiles the allele frequency tables needed for the other parts of this package such as sim.

Usage

fetchBMdata(url = NULL, id = NULL)

Value

A list consisting of six elements corresponding to the six populations detailed in the data set. Each of the list elements is a list in itself with three further elements named loci, profiles and freqs. loci is a vector of the 13-20 STR locus names. freqs is a list of 13-20 vectors, each vector contains the allele frequencies. profiles contains the raw profiles that the allele frequency tables were constructed from.

Arguments

url

- the location of the webpage this data is stored on. If NULL then hardcoded values in the function are used. The argument allows the user to get the function to work given this values may change. However, it is unlikely that it will help.

id

- the id of the HTML element where the data is stored on the webpage. If NULL then a hardcoded value in the function is used. The argument allows the user to get the function to work given this values may change. However, it is unlikely that it will help. NOTE: this is super flakey because of how the FBI web authors have created it. This may change in which case, the function will more likely change than the id.

Details

The first three populations have data on 20 loci, the second three on 13 loci. The missing values (0's in the raw data) have been dropped and are not used in calculating the frequencies. This function will not work if you are not connected to the internet, or access to the internet is blocked.
