fuzzygenet: Reading a table of genetic data (diploid individuals)

Description

Reads data like char2genet without a priori population

Usage

fuzzygenet(X)

Arguments

X

a data frame of strings of characters (individuals in row, locus in variables), the value coded '000000' or two alleles of 6 characters

Value

• returns a data frame with the 6 following attributs:
• col.blocks
  a vector containing the number of alleles by locus
• all.names
  a vector containing the names of alleles
• loc.names
  a vector containing the names of locus
• row.w
  a vector containing the uniform weighting of rows
• col.freq
  a vector containing the global allelic frequencies
• col.num
  a factor ranking the alleles by locus

Details

In entry, a row is an individual, a variable is a locus and a value is a string of characters, for example, 012028 for a heterozygote carying alleles 012 and 028; 020020 for a homozygote carrying two alleles 020 and 000000 for a not classified locus (missing data). In exit, a fuzzy array with the following encoding for a locus: 0 0 1 ...0 for a homozygote 0 0.5 0.5 ...0 for a heterozygote p1 p2 p3 ...pm for an unknown where (p1 p2 p3 ...pm) is the observed allelic frequencies for all tha available data.
