Generating a histogram by subsampling without replacement.

1	preseqR.nonreplace.sampling(n, size)

`n`	A two-column matrix. The first column is the frequency j = 1,2,…; and the second column is N_j, the number of species represented exactly j times in the initial sample. The first column must be sorted in an ascending order.
`size`	An positive integer representing the size of the subsample.

preseqR.nonreplace.sampling generates a subsample by sampling the initial sample without replacement. sample in R is used to implement the function. We wrap up this function in such a way that both the input and the output are histograms.

A two-column matrix as a subsample. The first column is the frequency j = 1,2,…; and the second column is N_j, the number of species represented j times in the subsample.
