Summarytools

_GitHub-only_ release

- Introduced `ctable()` for cross-tabulations
- Extended support for printing objects created using `by()` and/or `with()`:
variable names, labels and by-groups are now displayed correctly
- `view()` is now more than just a wrapper function for the `print()` method;
it is the function to use when printing an object created with `by()`
- Appending to summarytools-generated html files is now possible
- Most pander options stored in summarytools objects can be overridden by
`print()` or `view()`
- `freq()` has an new parameter, 'order', allowing to order rows by count
rather than values
- Alignment of numbers in `descr()` observations table has been improved

Backward Compatibility Note

The 'file' parameter must now be used with `print()` or `view()`; its
use with other functions is now deprecated.

- Improved the way `dfSummary()` reports frequencies for character variables
- Fixed problems with outputs when using weights
- Added hash markup to table headings for better markdown integration
- Added an option to the `print()` method to suppress the footnote in HTML
outputs
- Fixed a problem with `dfSummary()` which arose when number of factor levels
exceeded max.distinct.values

- Added Introductory vignette
- Fixed _markdown_ output that would not render strings such as <NA>
- Improved multiline tables line feeds
- Improved sample datasets
- Removed _Bootstrap_ content not likely to be used
- Changed the way `method = "browser"` sends file path to browser for better
cross-platform compatibility
- Improved results when using `by()`
