    longDescription = ''
      GNU R is a language and environment for statistical computing and
      graphics that provides a wide variety of statistical (linear and
      nonlinear modelling, classical statistical tests, time-series
      analysis, classification, clustering, ...) and graphical
      techniques, and is highly extensible. One of R's strengths is the
      ease with which well-designed publication-quality plots can be
      produced, including mathematical symbols and formulae where
      needed. R is an integrated suite of software facilities for data
      manipulation, calculation and graphical display. It includes an
      effective data handling and storage facility, a suite of operators
      for calculations on arrays, in particular matrices, a large,
      coherent, integrated collection of intermediate tools for data
      analysis, graphical facilities for data analysis and display
      either on-screen or on hardcopy, and a well-developed, simple and
      effective programming language which includes conditionals, loops,
      user-defined recursive functions and input and output facilities.
