Tools for Descriptive Statistics
A collection of miscellaneous basic statistic functions and convenience wrappers for efficiently describing data. The author's intention was to create a toolbox, which facilitates the (notoriously time consuming) first descriptive tasks in data analysis, consisting of calculating descriptive statistics, drawing graphical summaries and reporting the results. The package contains furthermore functions to produce documents using MS Word (or PowerPoint) and functions to import data from Excel. Many of the included functions can be found scattered in other packages and other sources written partly by Titans of R. The reason for collecting them here, was primarily to have them consolidated in ONE instead of dozens of packages (which themselves might depend on other packages which are not needed at all), and to provide a common and consistent interface as far as function and arguments naming, NA handling, recycling rules etc. are concerned. Google style guides were used as naming rules (in absence of convincing alternatives). The 'camel style' was consequently applied to functions borrowed from contributed R packages as well.

- PlotLinesA will use lines instead of usr coordinates for placing the
legend text. The distance of line segements can now be controlled in more

organically and organized chaotically (for not saying: not organized at all ...).
See ?DescToolsOptions for all the details.
"fixedfont" must now be defined as list, "footnote", "col" are now vectors instead
single values and formats (fmt) are organized as list. (see also new function Fmt()).

- IsDichotomous gets a new argument strict for checking for strictly two levels
and a na.rm argument, which is set to FALSE by default.
- PairApply simply overwrote the diagonal with 1, which was inappropriate.
Functions are now also evaluated for diagonal elements.
- TOne would not have displayed column names, in case there were only
boolean variables in the data.frame to describe. (credits to Beat Bruengger)

repetitions respecting order. (credits to Carlos Redondo-Figuero)
- PlotDot erroneously reversed the order of datapoints, when simultaneously
supplied with group data and error bars.
- TOne would not have displayed variables with just one unique value.
- The data.frame interface for Label was ambiguous. A data.frame is now

now be FALSE by default.
- PlotFdist gets a new argument args.curve.ecdf allowing to superpose
a function to the ecdf-plot.
- PlotFdist's default argument for the bw of the density curve changes to
bw = "SJ", which turns out to be the better default for n < 1000.
- Large and Small have been recoded in C++ (thanks to Nathan Russel) to run
faster and get a renamed argument (na.last instead of na.rm).
So far they are supposed be the fastest on the market...

resulted in incorrect unique and extreme values.

KNOWN PROBLEMS / TODOS:
- Leading zeros and big.mark can not be used together in Format.
- DoCounts should get an O(n log(n)) implementation, containig std. errors.
- We have not reached our goal yet - documentation is still not finalized, some functions
not tested thoroughly enough, others have rather a proof of concept status -

function interfaces, ensuring consistency with R-standards and DescTools
conventions will be performed next.

- MeanCI has been enhanced to calculate confidence intervals for trimmed means.
- StrVal gains two new arguments paste and as.numeric.
- Many smaller changes on the documentation and helpfiles.
- PairApply argument "symmetric" gets another default value: "FALSE" instead of "TRUE".
This seems more robust, as the other way round potential errors are more likely.
- WhichNumerics, WhichFactors, WhichFlags are not needed anymore.
which(sapply(x, IsNumeric)), sapply(x, IsDichotmous), sapply(x, is.factor) do the job.
- DescFactFact is a relict and obsolete. Use of Desc.formula or Desc.table is recommended.
- FormatFix and FormatSig have been replaced by the new function Format.
- Explore has been removed because of its dependency for the package "manipulate"
(which is not on CRAN). It might be added again built on tcltk down the road.
- plotit was not correctly interpreted in Desc.factor (credits to Thomas Schlesinger).
- PlotVenn did not correctly place the figures in the 2-sample case (credits to Andrew Marritt).

- DescToolsOptions gains a default argument allowing to reset the options.
- WrdText allows to set some paragraph format and text color now.
- anyNA is only defined for R >= 3.1, the according dependency has been defined.
- the key.ico file has been placed in /extdata directory and should definitely
be found now by the function PasswordDlg(). (shame on me..)

- The function "AddErrBars" has been renamed to "ErrBars".
- The function "AddLm" has been redesigned to "lines.lm".

- PlotFdist has a new option "curve" to be used to add e.g. a normal density
curve to the histogram.
- AndersonDarlingTest calculation logic was replaced with the newer Marsaglia approach.
(I'm not sure, whether this was wise. Tell me what you think about that!)
- JarqueBeraTest gains a new argument robust, calculation a robust version of the test.
- StrPad has been given recycling power for all arguments. The "str" argument has
been renamed to "pad".
- The argument "type" in MeanCI, MeanDiffCI, MedianCI, VarCI has been renamed to "method"
such as to be consistent with others CIs.
- The argument verb in Desc.table has been renamed to "verbose" and its allowed
values to "medium", "low" and "high". Anyhow this change will not break existing
code, as abbreviation is allowed.
- Desc-functions have been cleared out, resulting in better consistency and faster
and more robust behaviour.
- LOCF gets a faster implementation.
- Bug corrected for Cramer's V confidence intervals.
Credits to Steven J. Pierce for spotting the problem and to Michael Smithson for fixing it.
- The icon file for the PasswordDlg could not be found resulting in the dialog not being displayed.
- PlotFdist did not handle args.boxplot = NA correctly, meaning no boxplot being displayed.

- LsFct did not only list the functions but all objects of a package.
- StrChop did not chop the last part of the string correctly.
- DescWrd would not have run on Word versions other than German because of a local template name.
This should be fixed for all language versions now.
