在尝试使用rvg选项将ggplots绘制到幻灯片时，我似乎收到了导致RStudio崩溃的错误。
文档建议类似的方法应该起作用：

以下是我正在使用的代码：
arr2以下是我的会话信息：
require(ggplot2)
require(rvg)
require(officer)
doc <- read_pptx()
doc <- add_slide(doc, "Title and Content", "Office Theme")
mm <-ggplot(mtcars,aes(x=cyl))+geom_bar(stat='count')
#doc <- rvg::ph_with_vg_at(x=doc, ggobj=mm,left = 1, top = 2, width = 6, height = 4) # This automatically causes R to exit....
value = dml(ggobj=mm) # This works....
loc_data <- ph_location(left = 1, top = 2, width = 6, height = 4) # this works too....
doc <- officer::ph_with(doc, value, location = loc_data) #...this line does NOT work....
#doc <- officer::ph_with(doc, value, location = ph_location_type(type = "body")) #...this line does not work....
#doc <- officer::ph_with(doc, value, location = ph_location(left = 1, top = 2, width = 6, height = 4)) #...this line does not work either....
print(doc, target = "test_output.pptx")
我已经解决了原始问题，现在收到以下错误消息：

删除上面的quo...。导致R崩溃并自动退出。
