function makeroundtabs

This function creates a set of consistently rounded frequency count tables or hypercubes by means of a version of small count rounding.

makeroundtabs(
  A,
  b = 3,
  d,
  micro = "TRUE",
  sort,
  control,
  nin = "n",
  nout = "n",
  minit = 3,
  maxit = 3,
  maxdiff = 5,
  seed
)

`A`	A data frame representing a micro dataset or a frequency count hypercube. The (first) columns define the variables. If A is a hypercube the last column contains the number of units in each cell. If A is a micro dataset it is reduced to hypercube by the function aggrtab.
`b`	Rounding base. Counts in A less than b tat are contributing to counts less than b in the marginal cubes D are selected from A. The selected dataframe is called B
`d`	A list d{[[j]]} whose elements are vectors of variable names from A defining marginal tables/cubes D of A that we are interested in.
`micro`	Logical. TRUE if A is a micro dataset (default). FALSE if A i a frequency count hypercube.
`sort`	An ordered list of variables in hypercubes in D meant for priority sorting of the reduced hypercube B before rounding. Not all variables in D should be included.
`control`	A list of marginals of the hypercubes in D where deviations of aggregated rounded counts are checked against original counts.
`nin`	Name of count variable if A is a hypercube. Default name: "n".
`nout`	Name of the frequency count variable in the output tables.
`minit`	Minimum number of searches to be carried out.
`maxit`	Maximum number of searches to be carried out.
`maxdiff`	If maximum difference in "control" is no larger than maxit, the stop search.
`seed`	Input seed for first systematic random search.

Ar: The rounded version of A

Br: The rounded version of B

D: The original hypercube of interest.

Dr: The rounded version of D. The final table of interest.

maxdiff: The largest absolute difference between cells D and Dr among cells in the control list.

nmaxdiff: The number of occurences if Maxdiff
