An R implementation of quality control–based robust LOESS(local
    polynomial regression fitting) signal correction for metabolomics data
    analysis, described in Dunn, W., Broadhurst, D., Begley, P. et al. (2011)
    <doi:10.1038/nprot.2011.335>. The optimisation of LOESS's span parameter
    using generalized cross-validation (GCV) is provided as an option. In
    addition to signal correction, 'qcrlscR' includes some utility functions
    like batch shifting and data filtering.

Simulates a 5 qubit Quantum Computer and evaluates quantum circuits with 1,2
             qubit quantum gates.

Quantile correlation-sure independence screening (QC-SIS) and composite quantile correlation-sure independence screening (CQC-SIS) for ultrahigh-dimensional data.

Primarily, the 'qcv' package computes key indices related to the Quantifying Construct
    Validity procedure (QCV; Westen & Rosenthal, 2003 <doi:10.1037/0022-3514.84.3.608>; 
    see also Furr & Heuckeroth, in press). The qcv() function is the heart of the 'qcv' package, 
    but additional functions in the package provide useful ancillary information related to the QCV procedure.

Automates many of the tasks associated with quantitative discourse analysis of transcripts containing discourse
              including frequency counts of sentence types, words, sentences, turns of talk, syllables and other assorted
              analysis tasks. The package provides parsing tools for preparing transcript data. Many functions enable the user
              to aggregate data by any number of grouping variables, providing analysis and seamless integration with other R
              packages that undertake higher level analysis and visualization of text. This affords the user a more efficient
              and targeted analysis. 'qdap' is designed for transcript analysis, however, many functions are applicable to other
              areas of Text Mining/ Natural Language Processing.

A collection of text analysis dictionaries and word lists for use with
        the 'qdap' package.
