schemaOnRead: Automated Schema on Read

Description Usage Arguments See Also Examples

View source: R/SchemaOnRead.R

Description

Provides schema-on-read tools including a single function call (e.g., schemaOnRead("filename")) that reads text (TXT), comma separated value (CSV), raster image (BMP, PNG, GIF, TIFF, and JPG), R data (RDS), HDF5 ('H5'), NetCDF ('CS'), spreadsheet (XLS, XLSX, ODS, and DIF), Weka Attribute-Relation File Format (ARFF), Epi Info (REC), Pajek network (PAJ), R network (NET), Hypertext Markup Language (HTML), SPSS (SAV), Systat (SYS), and Stata (DTA) files. It also recursively reads folders (e.g., schemaOnRead("folder")), returning a nested list of the contained elements.

The standard use of SchemaOnRead is to recursively load a folder. The result is a named list of elements for each entry in the folder's tree. Sub-elements (e.g., files or subfolders) of a folder can be accessed using the R named list ("\$") operator followed by the sub-element name. Files or folders with names that do not conform to standard R variable naming requirements can be accessed using single quote notation (e.g., "results$'Nonconforming Name!'"). schemaOnRead(path).
