LSHR: Locality Sensitive Hashing in R

Calculates "S-curve". This is used to pick number of hash functions and bands which provides tradeoff between precision and recall for approximate near neighbor search.

1 2	get_s_curve(number_hashfun, n_bands_min = 1, n_rows_per_band_min = 1, plot = interactive())

`number_hashfun`	guess about number of hash functions to use
`n_bands_min`	don't plot s-curves for number of bands less than `n_bands_min`
`n_rows_per_band_min`	don't plot s-curves for number of rows less than `n_rows_per_band_min`
`plot`	logical, whether to plot s-curves.
