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
.
