R2wd (version 1.1)

R2wd-package: Write MS-Word documents from R.

Description

R2wd uses the StatconnDCOM server via rscproxy and rcom to communicate with MS-Word via the COM interface (Windows only). R2wd can be seen as a collection of convenience wrappers to calls of functions in the rcom package.

Details

ll{ Package: R2wd Type: Package Version: 1.1 Date: 2009-10-23 License: GPL-2 LazyLoad: yes } If Word is not already running, wdGet() opens a new Word document, otherwise, it establishes a COM handle to the instance which is already running. The functions wdTitle, wdHeader, wdBody, and wdParagraph can be used to inject text elements into Word. Moreover, bookmarks can be added via wdInsertBookmarks and wdGoToBookmark allows to navigate among the bookmarks which also exist. There is another set of convenience functions, wdSection, wdSubsection, and wdSubsubsection which insert headers of level 1, 2, or 3, start new 'Sections' in Word, and add bookmarks. Graphs and dataframes can be inserted into Word, by the wdPlot, wdTable commands. The wdTable command takes a dataframe or an array as arguments, creates a Word table of the appropriate dimensions and injects the content of the dataframe or array into it. It then formats the table in Word using elementary formating elements. The functions wdApplyTheme and wdApplyTemplate allow to work with themes and templates.

Examples

## rcom needs to be installed
if (!require(rcom)) warning("Install rcom first")
## This initializes the hook to Word
## if Word is already running it connects to it via StatconnDcom
## if not, it uses StatconnDcom to open word to create a new document
## and to connect to it.
wdGet()
## Then there is a set of small functions which implement elementary
## functionality:
wdTitle("R2wd, A Package for writing Word Documents from R",label="R2wd")
##
wdSection("Introduction")
##
wdBody("This is an example on how to use the R2wd package.")
##
## We can also plot data. The following line uses the default plot command
##
wdPlot(1:100,sin((1:100)/10),type="l",main="a test graph")
##
## The plot command can be exchanged for something else
##
wdPlot(mtcars,plotfun=pairs,main="a test graph",height=6,width=6,pointsize=8)
##
## we can also do something more elaborate (requires latticeExtra)
##
if (!require(latticeExtra)) warning("Install latticeExtra first")
fun<-function(...) print(useOuterStrips(xyplot(...)))
wdPlot(mpg~hp|cyl+carb,data=mtcars,plotfun=fun,height=6,width=6)
##
## There is also rudimentary way to transfer data frames.
##
wdTable(mtcars)
##
## It may be useful to format them first
##
wdTable(format(mtcars))
##
## Finally, we can apply themes and templates
##
wdApplyTheme("Quad 100")
wdApplyTheme("BlueCalm 100")
wdApplyTheme("None")
wdSave("MyDoc")
##
wdQuit()
