Suppose a parent sequence/string 'ABCDE' gets cut in various fragments (eg 'ABC','AB' ...).
countSameStartEnd
counts how many (ie re-occuring) start- and end- sites of edges do occur in the input-data.
The input is presented as matrix of/indicating start- and end-sites of edges.
The function is used to characterize partially redundant edges and accumulation of cutting/breakage sites.
countSameStartEnd(frag, minFreq = 2, nDig = 4)
(matrix) 1st column beg
start-sites, 2nd column end
end-sites of edges, rownames to precise fragment identities are recommended
(integer) min number of accumulated sites for taking into account (allows filtering with large datasets)
(integer) rounding: number of digits for columns beg.rat
and end.rat
in output
matrix of 6 columns: input (beg and end), beg.n, beg.rat, end.n, end.rat
