attack: attacking primary suppressed cells and calculating current...

Description Usage Arguments Value Author(s) Examples

Function attack is used to calculate lower and upper bounds for a given sdcProblem (stored as object of class sdcProblem-class). For all calculations the current suppression pattern is used when calculating solutions of the attacker's problem.

1	attack(object, verbose = FALSE)

`object`	an object of class `sdcProblem-class`
`verbose`	a logical vector specifying if output should be verbose (TRUE) or not (FALSE)

a data.frame with column 'index' holding indices of primary suppressed cells and columns 'bounds_min' and 'bounds_max' featuring calculated lower and upper bounds for each cell. Column 'protected' shows if a given cell is accordingly protected (TRUE) or not (FALSE).

problem <- get(load(fn))

# calculate current lower|upper bounds given current suppression pattern
