miss_hist creates a histogram of the proportion missing data (NA) per locus.
miss_hist()It will write to jpg file a histogram of NA proportions for the loci.
When run it uses the "loci_NA.csv", an output
from running amp_threshold, to produce a histogram to aid in
visualising data "missingness".
The plot is printed to screen and also saved as a jpg file to the `results/threshold/` sub-directory. It can be used to determine a "missingness" threshold for further data cleaning.
