Converting date ranges into dating 'steps' eases the
    visualization of changes in e.g. pottery consumption, style and other
    variables over time. This package provides tools to process and
    prepare data for visualization and employs the concept of aoristic
    analysis.

Interface with the 'Dat' p2p network protocol <https://datproject.org>. Clone archives from the network, share your own files, and install packages from the network.

Profiles datasets (collecting statistics and informative summaries 
    about that data) on data frames and 'ODBC' tables: maximum, minimum, mean, standard deviation, nulls,
    distinct values, data patterns, data/format frequencies.

Phone numbers are often represented as strings because there
    is no obvious and suitable native representation for them.  This leads
    to high memory use and a lack of standard representation.  The package
    provides integer representation of Australian phone numbers with optional
    raw vector calling code. The package name is an extension of 'au' and 'ph'.

Various utilities for the Davies distribution.

In applications it is usual that some additional information is available. This package dawai (an acronym 
      for Discriminant Analysis With Additional Information) performs linear and quadratic discriminant analysis with 
      additional information expressed as inequality restrictions among the populations means. It also computes several 
      estimations of the true error rate.

Programmatic interface to the 'Daymet' web services
    (<http://daymet.ornl.gov>). Allows for easy downloads of
    'Daymet' climate data directly to your R workspace or your computer.
    Routines for both single pixel data downloads and
    gridded (netCDF) data are provided.

Allows clinicians and researchers to compute daily dose (and subsequently days' supply) for prescription refills using the following methods: Fixed window, fixed tablet, defined daily dose (DDD), and Random Effects Warfarin Days' Supply (REWarDS). Daily dose is the computed dose that the patient takes every day. For medications with fixed dosing (e.g. direct oral anticoagulants) this is known and does not need to be estimated. For medications with varying dose such as warfarin, however, the daily dose should be assumed or estimated to allow measurement of drug exposure. Days’ supply is the number of days that patients’ supply of medication will last after each prescription fill. Estimating days’ supply is necessary to calculate drug exposure. The package computes days’ supply and daily dose at both the prescription and patient levels. Results at the prescription level are denoted with “-Rx-” and those at patient level are denoted with “-Pt-”.
