The forensicpopdata package provides allele frequency data for human genetic markers (STRs) commonly used in forensic genetics and kinship analysis. Currently two data sets are included:
NIST1036freqs)UKDNA17freqs)In addition, it is possible to access the STRidER
database through the read_STRidER_xml function.
The forensicpopdata package is not yet available
from CRAN. You can install the forensicpopdata package
using the pak package
in R:
# install.packages("pak")
pak::pak("mkruijver/forensicpopdata")The data function is used to load a data set.
require(forensicpopdata)
#> Loading required package: forensicpopdata
data(NIST1036freqs)The data set is a named list for each population:
names(NIST1036freqs)
#> [1] "AfAm" "Asian" "Cauc" "Hisp"For each population, a list of frequencies by locus name is available:
