The goal of 'readsdr' is to bridge the design capabilities from
    specialised System Dynamics software with the powerful numerical tools 
    offered by 'R' libraries. The package accomplishes this goal by parsing 
    'XMILE' files ('Vensim' and 'Stella') models into 'R' objects to construct 
    networks (graph theory); 'ODE' functions for 'Stan'; and inputs to simulate
    via 'deSolve' as described in Duggan (2016) <doi:10.1007/978-3-319-34043-2>.

Read and write labelled sparse matrices in text format as used by
    software such as 'SVMLight', 'LibSVM', 'ThunderSVM', 'LibFM', 'xLearn', 'XGBoost', 'LightGBM',
    and others. Supports labelled data for regression, classification (binary, multi-class, multi-label),
    and ranking (with 'qid' field), and can handle header metadata and comments in files.

Function to read and write the 'Stata' file format.

Functions for importing and handling text files and formatted text
    files with additional meta-data, such including '.csv', '.tab', '.json', '.xml',
    '.html', '.pdf', '.doc', '.docx', '.rtf', '.xls', '.xlsx', and others.

'Praat' <https://www.fon.hum.uva.nl/praat/> is a widely 
    used tool for manipulating, annotating and analyzing speech and 
    acoustic data. It stores annotation data in a format called a 
    'TextGrid'. This package provides a way to read these 
    files into R.

Reads and writes data frames to 'SQLite' databases
    while preserving time zones (for POSIXct columns), projections (for
    'sfc' columns), units (for 'units' columns), levels (for factors and
    ordered factors) and classes for logical, Date and 'hms' columns.  It
    also logs changes to tables and provides more informative error
    messages.

Import excel files into R. Supports '.xls' via the embedded
    'libxls' C library <https://github.com/libxls/libxls> and '.xlsx' via
    the embedded 'RapidXML' C++ library <https://rapidxml.sourceforge.net/>.
    Works on Windows, Mac and Linux without external dependencies.

Import data from 'Excel' binary (.xlsb) workbooks into R.
