Can't add ggplot2 objects onto a PPT slide

[phoebewong]

Hi,

I was trying to replicate the example code, but failed to add the ggplot2 plot onto the template ppt.

library(officer)
doc <- read_pptx()
if( require("ggplot2") ){
  doc <- add_slide(doc, layout = "Title and Content",
                   master = "Office Theme")
  gg_plot <- ggplot(data = iris ) +
    geom_point(mapping = aes(Sepal.Length, Petal.Length),
               size = 3) + theme_minimal()
  doc <- ph_with_gg(x = doc, value = gg_plot, type = "body" )
}
print(doc, target = "first_example.pptx") 

Here's the error message I got:

Error in external_img(file, width = width, height = height) : 
  file.exists(src) is not TRUE
In addition: Warning message:
In png(filename = file, width = width, height = height, units = "in",  :

Let me know if you have any clue of the error!

Thanks, Phoebe

Thanks Phoebe

I have no clue. I am not able to reproduce the error and it does not happen on CRAN nor travis. Can you run example of ph_with?

[phoebewong]

Hey David, hmm that's odd. The other examples worked for me, only the ggplot one did not.

Another officer user Megan has let me know that she ran into the same issue and solved by downloading XQuartz (from online) and the Cairo R package, in case anyone else also run into this issue in the future. Thanks for all the great work!
