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
dml and 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")Function xl_add_vg() is the equivalent for Excel
workbooks.
doc <- read_xlsx()
doc <- xl_add_vg(doc, sheet = "Feuil1", code = print(gg),
width = 6, height = 6, left = 1, top = 2 )
print(doc, target = "vg.xlsx")By default, theses graphics are editable, element edition
can be disabled with option editable = FALSE.
