run_admixture: run admixture Reps times at each of K values
In eriqande/genoscapeRtools: Tools for building migratory bird genoscapes

Just a wrapper to mclapply over all this.

run_admixture(
  bed,
  Reps = 2,
  Kvals = 2:5,
  path = ".",
  outdir = "admixture_runs",
  num_cores = max(1, parallel::detectCores() - 1),
  use_existing_directory = FALSE,
  more_flags = ""
)

`bed`	the bed file to use. (With the .bed extension. Example = "plink.bed".) The .bim file has to be with it in the same directory as well as the .fam file. These three files will both get copied to "input.bed" and "input.bim" in the "data" directory in the outdir
`Reps`	number or reps to do
`Kvals`	vector of K-values to use
`path`	the path that gets you to the directory you want to put all the results in.
`outdir`	the single name of the output directory you want
`num_cores`	the number of cores to parallelize the admixture runs over. By default it will try to detect the number of cores and then use 1 less than that. (or 1, whichever is larger). But you can set it to whatever...
`use_existing_directory`	If you want to place files into an existing outdir without throwing an error, set this to TRUE
`more_flags`	any additional flags to run admixture with
