Reading and writing data to and from files.

Abstract This chapter deals with reading and writing data to and from files, demonstrating the appending of data to an existing file, use of "read.delim" with non-tab separator, selection of a file to read interactively, use of excel for data entry, reading of PDF files for data mining, and writing of graphics directly to disc. The "readxl" function and tibbles are explained.
