Graphics API version mismatch

[lincj1994]

Hi. I used the graph2ppt and it returned an error:

Error in PPTX_(file, bg, width, height, offx = offx, offy = offy, pointsize = pointsize,  : 
  Graphics API version mismatch

This error is not thrown directly by export but seems rather linked to dependencies. I need more info to better understand your issue:

1. Does your machine support graphical display (usually not the case when working from a server)? Could you provide the output of

   capabilities()

2. Are you able to plot your graph before running graph2ppt? Would you have a small example that I could use to replicate the issue?
3. What is your session information? It is the output of

   sessionInfo()

Thanks for your reply. The output of

I ran grapn2ppt after I have plot my graph.

> df <- data.frame(V1 = rnorm(100), V2 = rnorm(100))
> ggplot(df, aes(x = V1, y = V2)) + geom_point()
> graph2ppt(file = 'df.pptx', width = 6, height = 5)
Error in PPTX_(file, bg, width, height, offx = offx, offy = offy, pointsize = pointsize,  : 
  Graphics API version mismatch

[cvanderaa]

Hmm I don't see an obvious solution here... Do you get the same issue when you run this?

df <- data.frame(V1 = rnorm(100), V2 = rnorm(100))
gg <-  ggplot(df, aes(x = V1, y = V2)) + geom_point()
graph2ppt(gg, file = 'df.pptx', width = 6, height = 5)

[lincj1994]

Yes :(

[cvanderaa]

Ok let's try to find where the error exactly occurs. export is depending on rvg and officer to generate ppt files. Do you have any error when running this example code (taken from the rvg README)?

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")

[lincj1994]

Hi. Sorry for the late reply.

The R News for 4.1.0 state: The graphics engine version, R_GE_version, has been bumped to 14 and so packages that provide graphics devices should be reinstalled.

I have reinstalled Cairo package and solved the problem.

Excellent, thanks for the update!
