Frac

MaxDigits

Ndec

Prec

the numeric value (or a vector of numerics), whose fractional part is to be calculated.

if <code>dpwr</code> is not missing, the fractional part will be multiplied by 10^dpwr and returned rounded to integer. Defaults to NA.

dpwr

<code>Frac</code> returns the fractional part of a numeric value. MaxDigits return the number of digits in x. 
<code>Ndec</code> returns the number of decimals and <code>Prec</code> the precision of a number <code>x</code>.

 arith 

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.
