Getting error with ggplot2 when exporting to pptx

[schuettl]

Hi there,
thanks for the development of this supercool package!
I got stuck on a strange error, I am not sure if it's a bug, or if it's me...

My example:

library("officer")
library("ggplot2")
library("tidyverse")
p1 <- ggplot(tibble(x=1,y=2,z=4))+geom_point(aes(x=x,y=y))    

  
p_dml <- rvg::dml(ggobj = p1)
   officer::read_pptx() %>%
    officer::add_slide() %>%
    officer::ph_with(p_dml, officer::ph_location()) %>%
   base::print(
    target = here::here(
      "test",
      "test.pptx"
    )
  )

works completely fine, but

p2 <- ggplot(tibble(x=1,y=2,z=4))+geom_point(aes(x=x,y=y,color=z))  

p_dml <- rvg::dml(ggobj = p2)
officer::read_pptx() %>%
officer::add_slide() %>%
 officer::ph_with(p_dml, officer::ph_location()) %>%
 base::print(
  target = here::here(
    "test",
    "test.pptx"
  )
)

throws the error:

Error in open.connection(con, "rb") : cannot open the connection
In addition: Warning message:
In open.connection(con, "rb") :
  cannot open file '/tmp/RtmpKOBSCr/file27df431cbcd516/raster-rId000002.png': No such file or directory`

Am I doing something wrong here?

Thanks for your help!

hello

No, your code is totally fine.

It is a bug that is fixed. You need to update from github the package rvg.

davidgohel/rvg@71416df

I am sorry, I just realized I forgot to send this version to CRAN!

Thanks for reporting this

[davidgohel]

An issue has been opened here: davidgohel/rvg#53 and will be closed when version 0.3.3 will be on CRAN (soon)

[schuettl]

Thanks a lot for the quick answer. With the rvg - Update from Github it now works perfectly!
