DescTools (version 0.99.56)

DescTools-package: Tools for Descriptive Statistics and Exploratory Data Analysis

Description

DescTools is an extensive collection of miscellaneous basic statistics functions and comfort wrappers not available in the R basic system for efficient description of 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. Special attention was paid to the integration of various approaches to the calculation of confidence intervals. For most basic statistics functions, variants are included that allow the use of weights. The package contains furthermore functions to produce documents using MS Word (or PowerPoint) and functions to import data from Excel.
A considerable part 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 'CamelStyle' was consequently applied to functions borrowed from contributed R packages as well.

Feedback, feature requests, bugreports and other suggestions are welcome! Please report problems to Stack Overflow using tag [desctools] or directly to the maintainer.

Arguments

Warning

This package is still under development. Although the code seems meanwhile quite stable, until release of version 1.0 (which is expected in hmm: near future?) you should be aware that everything in the package might be subject to change. Backward compatibility is not yet guaranteed. Functions may be deleted or renamed and new syntax may be inconsistent with earlier versions. By release of version 1.0 the "deprecated-defunct process" will be installed.

MS-Office

To make use of MS-Office features you must have Office in one of its variants installed, as well as the package RDCOMClient. This package uses the COM interface to control the Office applications. There is no direct equivalent to COM interface for Mac or Linux, hence the use of these functions is restricted to Windows systems. All Wrd*, XL* and Pp* functions require this basis to run.

RDCOMClient can be installed with:

install.packages("RDCOMClient", repos="http://www.omegahat.net/R")

The omegahat repository does not benefit from the same update service as CRAN. So you may be forced to install a package compiled with an earlier version, which usually is no problem. For R 4.2 you can use:


url <- "http://www.omegahat.net/R/bin/windows/contrib/4.2/RDCOMClient_0.96-1.zip"
install.packages(url, repos=NULL, type="binary")

RDCOMClient does not exist for Mac or Linux, sorry.
