Distance metric is used to calculate the mean distance between the true plot and all the null plots in a lineup. The mean distances of each null plot to all the other null plots are calculated. The mean distances are returned for all the plots in the lineup.
calc_mean_dist(lineup.dat, var, met, pos, dist.arg = NULL, m = 20)lineup data of the lineup
a vector of names of the variables to be used to calculate the mean distances
distance metric needed to calculate the distance as a character
position of the true plot in the lineup
a list or vector of inputs for the distance metric met; NULL by default
number of plots in the lineup, by default m = 20
the mean distances of each plot in the lineup
