minCount

the minimum count for a package to display. minCount = 1 displays all packages. The default is the minimum of the input minCount and the count for package number minPackages.

Details

Return an object of class c('summary.findFn', 'list') with summary information on only packages satisfying the minPackages and minCount criteria. The minPackages and minCount components of the summary output list will be adjusted as necessary to match characteristics of object. The print method for a summary.findFn object will display the minCount, but minPackages will be a component of the returned object without being printed.
