MPgetRandomSubspaces: Produce a list of randomly selected feature sets

In tkonopka/MultiPattern: Multi-Pattern Discovery Framework

Description

Note: this function is not guaranteed to produce the specified number of features (it might produce less).

Usage

MPgetRandomSubspaces(f, n, d = 4, oversample = 4)

Arguments

f	character or integer vector, feature set
n	integer, number of required feature sets
d	integer, dimension of the required subspaces
oversample	numeric, used in randomization process (only becomes relevant when function starts to return fewer subspaces than requested, see description above)

Details

For example, if a feature set is of length 3 and user requets 5 sets of size 3, the output will contain only 1 (because there are not others).

If a feature set is of length 6 and user requests 20 sets of length 3, the output might contain fewer than 20. Although in this case there are exactly 20 sets of length 3, the randomization might not find them all. In such cases, try increasing the setting oversample.
