Data Management Package (Exposure and Occurrence Data in R) R package eoR version 0.4.0 This data management package provides some helper classes for publicly available data sources (HMD, DESTATIS) in Demography. Similar to ideas developed in the Bioconductor project <https://bioconductor.org> we strive to encapsulate data in easy to use S4 objects. If original data is provided in a text file, the resulting S4 object contains all information from that text file. But the information is somehow structured (header, footer, etc). Further the classes provide methods to make a subset for selected calendar years or selected regions. The resulting subset objects still contain the original header and footer information. Software Depends: R (>= 3.2.0) Imports: methods, data.table Rainer Walke <walke@demogr.mpg.de> Comprehensive R Archive Network (CRAN) Rainer Walke [aut, cre] (ORCID: <https://orcid.org/0000-0002-4269-6531>) GPL-3 2019-11-10 application/tgz https://CRAN.R-project.org/package=eoR doi:10.32614/CRAN.package.eoR
