HistDif: Customizes the positions of legend and p value in a histogram

Description

The positions of legend and p value in the histogram generated from function StrDif may not be ideal for different (permutations on differences of normalized Levenshtein distances) situations. HistDif customizes the positions of legend and p value in the histogram of the statistical difference of two groups of strings.

Usage

HistDif(dif.vec, obsDif, pvalue, o.x = 0.01, o.y = 0, p.x = 0.015, p.y = 0)

Arguments

dif.vec

Vector containing differences of normalized Levenshtein differences (LD) from the permutation test.

obsDif

The "observed" or original difference between between-group and within-group normalized LD.

pvalue

p value of the permutation test.

o.x

x coordinate of the legend in the histogram, default is 0.01.

o.y

y coordinate of the legend in the histogram, default is 0.

p.x

x coordinate of the p value in the histogram, default is 0.015.

p.y

y coordinate of the p value in the histogram, default is 0.

Details

The default values of o.y and p.y are 0. They are actually related to the number of permutations (num_perm): o.y is above 0.2 * num_perm, and p.y is below 0.2 * num_perm. If non-default values are used, the values become absolute y coordinates.
