A simple wrapper to mark
the plot instructions as Vector Graphics instructions. It produces
an object of class 'dml' with a corresponding method ph_with.
The function enable usage of any R plot with argument code and with
ggplot objects with argument ggobj.
dml( code, ggobj = NULL, bg = "white", fonts = list(), pointsize = 12, editable = TRUE, ... )dml( code, ggobj = NULL, bg = "white", fonts = list(), pointsize = 12, editable = TRUE, ... )
code |
plotting instructions |
ggobj |
ggplot object to print. argument code will be ignored if this argument is supplied. |
bg, fonts, pointsize, editable

unused arguments |
When dealing with a ggplot object argument bg will have no effect
because ggplot theme is specifying background color, don't forget
to define the colors you want in the theme:
theme( panel.background = element_rect(fill = "#EFEFEF"), plot.background = element_rect(fill = "wheat"))
anyplot <- dml(code = barplot(1:5, col = 2:6), bg = "wheat") library(officer) doc <- read_pptx() doc <- add_slide(doc, "Title and Content", "Office Theme") doc <- ph_with(doc, anyplot, location = ph_location_fullsize()) fileout <- tempfile(fileext = ".pptx") # fileout <- "vg.pptx" print(doc, target = fileout)anyplot <- dml(code = barplot(1:5, col = 2:6), bg = "wheat") library(officer) doc <- read_pptx() doc <- add_slide(doc, "Title and Content", "Office Theme") doc <- ph_with(doc, anyplot, location = ph_location_fullsize()) fileout <- tempfile(fileext = ".pptx") # fileout <- "vg.pptx" print(doc, target = fileout)

file |
the file where output will appear. |
height, width
|
Height and width in inches. |
offx, offy
|
top and left origin of the plot |
bg |
Default background color for the plot (defaults to "white"). |
fonts |
Named list of font names to be aliased with
fonts installed on your system. If unspecified, the R default
families When you use specific fonts, you will need that font installed on your system.
This can be check with package An example: |
pointsize |
default point size. |
editable |
should vector graphics elements (points, text, etc.) be editable. |
id |
specifies a unique identifier (integer) within the slide that will contain the DrawingML instructions. |
last_rel_id |
specifies the last unique identifier (integer) within relationship file that will be used to reference embedded raster images if any. |
raster_prefix |
string value used as prefix for png files produced when raster objects are printed on the graphical device. |
standalone |
produce a standalone drawingml file? If |

produces a vector graphics output from R plot instructions
stored in a dml object and add the result in an rpptx
object produced by read_pptx.
