`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).
```{r eval=FALSE}
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.
```{r eval=FALSE}
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`.
## Installation
You can get the development version from GitHub:
```{r eval=FALSE}
devtools::install_github("davidgohel/rvg")
```
Install the CRAN version:
```{r eval=FALSE}
install.packages("rvg")
```
