This package is built upon a duration hidden Markov model proposed in Xi et al 2010 and Wang et al 2008. The core of the package was written in Fortran. Three functions including \code{predNuPoP}, \code{readNuPoP}, and \code{plotNuPoP} are provided for nucleosome positioning prediction, prediction results readin, and prediction results visualization respectively. The input DNA sequence can be of any length. } \details{ \tabular{ll}{ Package: \tab NuPoP\cr Type: \tab Package\cr Version: \tab 1.0\cr Date: \tab 2010-06-24\cr License: \tab GPL-2\cr } \code{predNuPoP}: R function invoking Fortran codes to predict nucleosome positioning, nucleosome occupancy and binding affinity. \code{readNuPoP}: R function to read in the prediction results by \code{predNuPoP}. \code{plotNuPoP}: R function to visualize predictions. } \author{ Ji-Ping Wang, Liqun Xi Maintainer: Ji-Ping Wang } \references{ Xi, L., Fondufe-Mittendorf, Y., Xia, L., Flatow, J., Widom, J. and Wang, J.-P.
