Usage

read_allele_freqs(filename, remove_zeroes = TRUE, normalise = TRUE)

Arguments

filename

Path to csv file.

Details

Reads allele frequencies from a .csv file. The file should be in FSIgen format, i.e. comma separated with the first column specifying the allele labels and one column per locus. The last row should be the number of observations. No error checking is done since the file format is only loosely defined, e.g. we do not restrict the first column name or the last row name.

Examples

# NOT RUN {
# below we read an allele freqs file that comes with the package
filename <- system.file("extdata","FBI_extended_Cauc.csv",package = "numberofalleles")
freqs <- read_allele_freqs(filename)
freqs # the output is just a list with an N attribute
# }
