Abstract

SchemaOnRead is a CRAN package that provides an extensible mechanism for importing a wide range of file types into R as well as support for the emerging schema-on-read paradigm in R. The schema-on-read tools within the package include a single function call that recursively reads folders with text, comma separated value, raster image, R data, HDF5, NetCDF, spreadsheet, Weka, Epi Info, Pajek network, R network, HTML, SPSS, Systat, and Stata files. It also recursively reads folders (e.g., schemaOnRead("folder")), returning a nested list of the contained elements. The provided tools can be used as-is or easily customized to implement tool chains in R. This paper’s contribution is that it introduces and describes the SchemaOnRead package and compares it to related R packages.
