ReporteRs is an R package for creating Microsoft Word and Powerpoint documents. It does not require any Microsoft component to be used. It runs on Windows, Linux, Unix and Mac OS systems. It is designed to automate reporting generation from R.
You can use the package as a tool for fast reporting and as a tool for reporting automation.
There are several features to let you format and present R outputs, for example:
FlexTableobjects let you format any complex table.
There are default templates and default values, it enables easy generation of R outputs in few lines of codes.
Below a short R script:
require( ggplot2 ) doc = docx( title = 'My document' ) doc = addTitle( doc , 'First 5 lines of iris', level = 1) doc = addFlexTable( doc , vanilla.table(iris[1:5, ]) ) doc = addTitle( doc , 'ggplot2 example', level = 1) myggplot = qplot(Sepal.Length, Petal.Length, data = iris, color = Species, size = Petal.Width ) doc = addPlot( doc = doc , fun = print, x = myggplot ) doc = addTitle( doc , 'Text example', level = 1) doc = addParagraph( doc, 'My tailor is rich.', stylename = 'Normal' ) filename <- tempfile(fileext = ".docx") # the document to produce writeDoc( doc, filename )
It lets you also create corporate documents, creation of complex tables, pretty graphical rendering with a set of R functions.
To automate document generation only R code is necessary.
With Word and PowerPoint document, you can add contents from R but also replace contents. By default, content is added at the end of the specified template document. When generating Word document, bookmarks can be used to define locations of replacements in the document. When generating PowerPoint document, slide indexes can be used to define locations of slides to replace in the presentation.
