Package of export isn't incompatible with ggbreak？

[Frank-plant]

ggbreak is helpful for plotting using ggplot2. However, after using ggplot2 combined with ggbreak, there is a error: Error in grid.newpage() : pptx device only supports one page when I use graph2ppt of package export to save plots as pptx.

p1=df_enzyme %>% ggplot(aes(Time,pro,fill=Treatment)) +
  stat_summary(fun = "mean", geom = "bar", alpha = .9, position = position_dodge(0.8),width=0.8) +
  stat_summary(geom = "errorbar",position = position_dodge(0.8),width = .2) +
  stat_compare_means(method = "t.test",label = "p.signif") +
  facet_grid(~Cultivar,labeller=labeller(Cultivar = c("1"="A. lagopoides","5"="P. antidotale","3"="U. setulosa"))) +
  scale_y_break(breaks= c(180,300),scales="free")+
  scale_fill_manual(values = c("#00AF46FF","#FF2643FF"))+
  theme_minimal(base_family = "serif",base_size=15)+
  theme(strip.text = element_text(face="bold.italic"))

graph2ppt(x=p1,file="report",append=T,margins=0)

there is a error: Error in grid.newpage() : pptx device only supports one page

When I don't use ggbreak, the error doesn't appear

p1=df_enzyme %>% ggplot(aes(Time,pro,fill=Treatment)) +
  stat_summary(fun = "mean", geom = "bar", alpha = .9, position = position_dodge(0.8),width=0.8) +
  stat_summary(geom = "errorbar",position = position_dodge(0.8),width = .2) +
  stat_compare_means(method = "t.test",label = "p.signif") +
  facet_grid(~Cultivar,labeller=labeller(Cultivar = c("1"="A. lagopoides","5"="P. antidotale","3"="U. setulosa"))) +
  #scale_y_break(breaks= c(180,300),scales="free")+
  scale_fill_manual(values = c("#00AF46FF","#FF2643FF"))+
  theme_minimal(base_family = "serif",base_size=15)+
  theme(strip.text = element_text(face="bold.italic"))

graph2ppt(x=p1,file="report",append=T,margins=0)

I want to know if it is possible to fix this error.
Cheers,

maybe you can try graph2ppt(x = print(p1), ...).

maybe you can try graph2ppt(x = print(p1), ...).

maybe you can try graph2ppt(x = print(p1), ...).

Thank you. That's great. This method has solved this error.
