rvg is providing two graphics devices that produces Vector Graphics outputs in DrawingML format for Microsoft PowerPoint with
dml_pptx and for Microsoft Excel with
dml_xlsx. Theses formats let users edit the graphic elements (editable graphics) within PowerPoint or Excel and have a very good rendering.
These raw XML outputs cannot be used as is. Functions
ph_with() have to be used with package
officer to add vector graphics in PowerPoint documents (
dml function is a simple wrapper to mark the plot instructions as Vector Graphics instructions).
library(rvg) library(ggplot2) library(officer) my_vec_graph <- dml(code = barplot(1:5, col = 2:6)) doc <- read_pptx() doc <- add_slide(doc, layout = "Title and Content", master = "Office Theme") doc <- ph_with(doc, my_vec_graph, location = ph_location_fullsize() ) print(doc, target = "my_plot.pptx")
xl_add_vg() is the equivalent for Excel workbooks.
By default, theses graphics are editable, element edition can be disabled with option
editable = FALSE. For more details, read officer article graphics.
