Importing and Creating Data

Abstract

When you are loading data into RStudio or R, you have options. R reads external objects using connection functions. The connections can be to files, Uniform Resource Locator (URL) addresses, pipes, or socket connections and can be an internal part of a function that reads from the connection, an argument to a function that reads from the connection, or a stand-alone function that opens a connection for reading (and, sometimes, writing). Some functions read textual data, some binary data, and some both kinds of data.
