| xlsx-package {xlsx} | R Documentation |
The xlsx package gives programatic control of Excel files using
R. A high level API allows the user to read a sheet of an xlsx
document into a data.frame and write a data.frame to a
file. Lower level functionality permits the direct manipulation of
sheets, rows and cells. For example, the user has control to set
colors, fonts, data formats, add borders, hide/unhide sheets,
add/remove rows, add/remove sheets, etc.
Behind the scenes, the xlsx package uses a java library from
the Apache project, http://poi.apache.org/index.html. This
Apache project provides a Java API to Microsoft Documents (Excel,
Word, PowerPoint, Outlook, Visio, etc.) By using the rJava
package that links R and Java, we can piggyback on the excellent work
already done by the folks at the Apache project and provide this
functionality in R. The xlsx package uses only a subset of the
Apache POI project, namely the one dealing with Excel files. All the
necessary jar files are kept in package xlsxjars that is
imported by package xlsx.
A collection of tests that can be used as examples are located
in folder /tests/. They are a good source of examples of how
to use the package.

The Java Doc detailing the classes: http://poi.apache.org/apidocs/index.html. This can be useful if you are looking for something that is not exposed in R as it may be available on the Java side. Inspecting the source code for some the the R functions in this package can show you how to do it (even if you are Java shy.)
