read_population: Read a raw text file in and translate appropriate columns...
In MarianaLag/Mlag: Tools Related to the Spatial Analysis of Genetic Marker Data

The function reads in a text file and does the proper translations for genotypes and spatial coordinates.

read_population(
  path,
  type,
  locus.columns,
  phased = FALSE,
  sep = ",",
  header = TRUE,
  delim = ":",
  ...
)

`path`	The path to the text file
`type`	An indication of what kind of loci that the data represent. The following kinds are recoginzed (n.b., if you have several types load them separately and `merge` them). missing The default. This will cause `read.population()` to read each column as a single locus with one allele aflp Encoded as 0,1 for absence/presence of bands. column Two columns of alleles per locus. separated Pre-separated alleles (with ':'). haploid One column per locus. snp Encoded by the number of minor alleles at the locus. zyme Alleles like zymes (e.g., 12 for '1' and '2' alleles). genepop Import data that is in 'genepop' format. cdpop Import genotypes encoded by CDPOP for subsequent analyses. structure Import a STRUCTURE data file (2 rows per individual format).
`locus.columns`	A vector indicating the numerical column number for each data type that will be treated as a `locus` object.
`phased`	A flag indicating the the alleles should are of known gametic phase (default=FALSE).
`sep`	The field separator for each column of the data.
`header`	A logical flag indicating if there is a header row (a good idea).
`delim`	The (optional) delimiter for alleles separators (default=":")
`...`	Optional parameters you can pass to `read.csv` or `read.table`.
