rvg package

Travis-CI Build Status Build status version cranlogs Active

rvg is a set of graphics devices that produces Vector Graphics outputs. This package is providing:

  • SVG (Scalable Vector Graphics) with dsvg. The graphic can be made interactive (tooltip, onclick and id attribute manipulation). To make that work in an HTML document, check for dependencies d3.js in the document. This is the svg device used by package ggiraph.
  • DrawingML 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_vg() and ph_with_vg_at() can be used with package officer to add vector graphics in PowerPoint documents.

library(rvg)
library(ggplot2)
library(officer)

doc <- read_pptx()
doc <- add_slide(doc, layout = "Title and Content", master = "Office Theme")
doc <- ph_with_vg(doc, code = barplot(1:10), type = "body")
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. For more details, read officer article graphics.
