Overview

About

Maintained by Michael NorthCRAN page ↗GitHub ↗

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'), 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.

Changes in 1.0.2

Changes:

The author gratefully acknowledges Hadley Wickham’s detailed and insightful suggestions for improvements to the code.
Refactored the code into separate source files.
Refactored file existence and extension checking into a single function call.
Updated the code to use quoted variable names instead of name modification.
Replaced the XML package with the xml2 package.
Replaced the XLConnect package with the readxl package.
Replaced the readstata13 package with the haven package.
Switched to using the haven package instead of foreign when possible.

url <- "https://cran.r-project.org/src/contrib/Archive/SchemaOnRead/SchemaOnRead_1.0.2.tar.gz"

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (1.0.2) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("drmichaelnorth/SchemaOnRead")

Development version from drmichaelnorth/SchemaOnRead. Installs pak first if it is not already available.
