Package designed to be used with Rscript to write
    '#!' shebang scripts that accept short and long flags/options.
    Many users will prefer using instead the packages optparse or argparse
    which add extra features like automatically generated help option and usage,
    support for default values, positional argument support, etc.

This is a command-line argument parser which wraps the 
    powerful Perl module Getopt::Long and with some adaptations for easier use
	in R.

A micro-package for reading "passwords", i.e.  reading
    user input with masking, so that the input is not displayed as it 
    is typed.  Currently we have support for 'RStudio', the command line
    (every OS), and any platform where 'tcltk' is present.

Allows get address and port 
	of the free proxy server, from one of two services
	<http://gimmeproxy.com/> or <https://getproxylist.com/>. 
	And it's easy to redirect your Internet connection through
	a proxy server.

Imports time series data from the 'Quandl' database <https://data.nasdaq.com/>. The package uses the  'json api' at <https://data.nasdaq.com/search>, local caching ('memoise' package) and the tidy format by default. 
   Also allows queries of databases, allowing the user to see which time series are available for each database id. In short, it is an alternative to package 'Quandl', with faster data importation in the tidy/long format.

Load polar volume and vertical profile data for
    aeroecological research directly into R. With 'getRad' you can access
    data from several sources in Europe and the US and standardize it to
    facilitate further exploration in tools such as 'bioRad'.

Automated General-to-Specific (GETS) modelling of the mean and variance of a regression, and indicator saturation methods for detecting and testing for structural breaks in the mean, see Pretis, Reade and Sucarrat (2018) <doi:10.18637/jss.v086.i03> for an overview of the package. In advanced use, the estimator and diagnostics tests can be fully user-specified, see Sucarrat (2021) <doi:10.32614/RJ-2021-024>.
