PowerPoint Interface | R Documentation |
A couple of functions to get R-stuff into MS-Powerpoint.
GetNewPP()
starts a new instance of PowerPoint and returns its handle. A new presentation with one empty slide will be created thereby. The handle is needed for addressing the presentation afterwards.
GetCurrPP()
will look for a running PowerPoint instance and return its handle. NULL
is returned if nothing's found.
PpAddSlide()
inserts a new slide into the active
presentation.
PpPlot()
inserts the active plot into PowerPoint. The image is transferred by saving the picture to a file in R and
inserting the file in PowerPoint. The format of the plot can be selected, as well as crop options and the
size factor for inserting.
PpText()
inserts a new textbox with given text and box properties.
GetNewPP(visible = TRUE, template = "Normal")
GetCurrPP()
PpAddSlide(pos = NULL, pp = DescToolsOptions("lastPP"))
PpPlot(type = "png", crop = c(0, 0, 0, 0), picscale = 100, x = 1, y = 1,
height = NA, width = NA, res=200, dfact=1.6, pp = DescToolsOptions("lastPP"))
PpText(txt, x = 1, y = 1, height = 50, width = 100, fontname = "Calibri", fontsize = 18,
bold = FALSE, italic = FALSE, col = "black", bg = "white",
hasFrame = TRUE, pp = DescToolsOptions("lastPP"))
