graph2office: Save currently active R graph to Microsoft Office / LibreOffice format

Description

Save the currently active R graph or a graph passed as an object or function to Microsoft Office / LibreOffice format with sensible defaults

Usage

graph2office(x = NULL, file = "Rplot", fun = NULL, type = c("PPT",
  "DOC"), append = FALSE, aspectr = NULL, width = NULL, height = NULL,
  scaling = 100, paper = "auto", orient = ifelse(type[1] == "PPT",
  "landscape", "auto"), margins = c(top = 0.5, right = 0.5, bottom = 0.5, left
  = 0.5), center = TRUE, offx = 1, offy = 1, upscale = FALSE,
  vector.graphic = TRUE, ...)
graph2ppt(...)
graph2doc(...)

Arguments

x

given ggplot2 plot or lattice plot object to export; if set to NULL the currently active R graph will be exported; not supported for base R plots.

file

name of output file. Any extension is ignored and added according to the requested output type.

fun

plot passed on as a function used to create it; useful especially for base R plots.

type

desired output type - DOC for Word document, PPT for Powerpoint.

append

logical value - if TRUE and type=PPT it will append the graph to the given file, where file can also be a given corporate template. If append=FALSE any existing file will be overwritten. Currently ignored in Word export.

aspectr

desired width to height aspect ratio. If set to NULL, the aspect ratio of the active graphics device is used.

width

desired width in inches; can be combined with a desired aspect ratio aspectr.

height

desired height in inches; can be combined with a desired aspect ratio aspectr.

scaling

scale width & height by a certain percentage.

paper

desired paper size to use - "A5" to "A1" for Powerpoint export, or "A5" to "A3" for Word output; default "auto" automatically selects the paper size that fits your graph. Graphs that are too large to fit on a given paper size are scaled down.

orient

desired paper orientation - "auto", "portrait" or "landscape"; default to "auto" for Word output and to "landscape" for Powerpoint.

margins

vector with the desired margins that should be left blank in

center

logical specifying whether or not to center the graph in the exported Powerpoint.

offx

if center is set to FALSE, the desired x offset at which to place one's graph in Powerpoint output.

offy

if center is set to FALSE, the desired y offset at which to place one's graph in Powerpoint output.

upscale

logical specifying whether or not to upscale one's graph to make it page-filling (excluding the margins). Note that scaling may result in a different look of one's graph relative to how it looks on the screen due to the change in size.

vector.graphic

logical specifying whether or not to output in editable, vector DrawingML format. Defaults to TRUE, in which case editing the plot in Powerpoint or Word is then possible after first ungrouping the plot elements. If set to FALSE, the plot is rasterized to PNG bitmap format at a resolution of 300 dpi.

…

any other options are passed on to rvg's dml_pptx function.

Value

NULL

Functions

• graph2ppt: Save currently active R graph to a Microsoft Office PowerPoint/LibreOffice Impress presentation

Examples

# NOT RUN {
# Create a file name
filen <- tempfile(pattern = "ggplot") # or 
# filen <- paste("YOUR_DIR/ggplot")

# Generate graphical output
library(ggplot2)
library(datasets)
x=qplot(Sepal.Length, Petal.Length, data = iris, 
        color = Species, size = Petal.Width, alpha = I(0.7))
plot.fun = function(){
  print(qplot(Sepal.Length, Petal.Length, data = iris, 
              color = Species, size = Petal.Width, alpha = I(0.7)))
}

# There are 3 ways to use graph2office():
### 1. Pass the plot as an object
graph2ppt(x=x, file=filen) 
graph2doc(x=x, file=filen, aspectr=0.5) 
### 2. Get the plot from current screen device
# }
# NOT RUN {
 # Because the example uses screen devices 
  x
  graph2ppt(file=filen, width=9, aspectr=2, append = TRUE)
  graph2doc(file=filen, aspectr=1.7, append =TRUE) 
# }
# NOT RUN {
### 3. Pass the plot as a function
# }
# NOT RUN {
 # Because the example uses screen devices 
  graph2ppt(fun=plot.fun, file=filen, aspectr=0.5, append = TRUE)
  graph2doc(fun=plot.fun, file=filen, aspectr=0.5, append = TRUE)
# }
# NOT RUN {
### Formatting options:
# Disable vectorized image export (export as a bitmap)
graph2ppt(x=x, file=filen, vector.graphic=FALSE, width=9, 
          aspectr=sqrt(2), append = TRUE) 
# Fill the slide with graph
graph2ppt(x=x, file=filen, margins=0, upscale=TRUE, append=TRUE) 
# etc...
# }
