write_population: Writes data frame with genotypes and other data to a file
In MarianaLag/Mlag: Tools Related to the Spatial Analysis of Genetic Marker Data

This is a basic output file formatter for saving files necessary for saving output in textual formats.

write_population(
  df,
  file,
  mode = c("text", "genepop", "structure", "dfdist")[1],
  stratum = NULL,
  ...
)

`df`	The `data.frame` to be written to the output.
`file`	The path to the file you want to write to.
`mode`	Which format to use for writing data to file. At present there are text Outputs all data columns with loci treated as colon separated. This is the default. genepop Saves genetic data into GENEPOP format. You must specify a stratum. structure Saves genetic data into the two-lined per individual STRUCTURE format. You must specify a stratum. dfdist Saves genetic data as a FDist, DFDist, DetSel file. You must specify the stratum.
`stratum`	An optional argument if using genepop or structure formats. By default, the 'text' option writes all data to file.
`...`	Other options to pass along (e.g., verbose=TRUE)
