r - 在 R studio 中将图形作为元文件复制到剪贴板时，如何提高 R 制作的图形的质量？

Question

当我在 中制作图形时R，我使用特定的美学设置。将图形另存为可PDF保持几乎所有元素的质量。但是当我复制图形时，metafile为了在或文档clipboard中使用它们，我失去了所有质量，即使我将文档另存为.doc.docxPDF

library (ggplot2)

Source <- c(rep("Water", 12), rep("Oil", 12))
Range <- rep((c(rep("First", 4), rep("Second", 8))),2)
Xaxis <- c(0,1,2,5,0,1,2,5,10,20,30,40,
           0,1,2,5,0,1,2,5,10,20,30,40)
Yaxis <- c(0,1,2,5,0,1,2,5,10,20,30,40,
           0,1,2,5,0,1,2,5,10,20,30,40)

DF <- data.frame(Source, Range, Xaxis, Yaxis)

#plot
p <- ggplot(data = DF, aes(x = Xaxis, y = Yaxis)) +
  geom_smooth(method = "lm") +
  geom_point() +
  facet_grid(Range~Source,
             scales = "free")

#Aesthetic settings
theme_set(
  theme_bw() +
    theme(line = element_line(colour = 1, size = 0.125),
          rect = element_rect(colour = 1, size = 0.125),
          text = element_text(colour = 1, size = 8),
          axis.title = element_text(face="bold", size = 8),
          axis.text = element_text(colour = 1, size = 8),
          axis.ticks = element_line(colour = 1),
          legend.title = element_text(face="bold", size = 8),
          legend.title.align = 0.5,
          legend.background = element_rect(fill = NA),
          legend.box.background = element_rect(colour = 1),
          panel.border = element_rect(colour = 1),
          strip.background = element_rect(colour = 1),
          strip.text = element_text(colour = 1, size = 8))
)

update_geom_defaults("point", list(size = 0.8))
update_geom_defaults("smooth", list(size = 0.125))
update_geom_defaults("linerange", list(size = 0.125))

绘图另存为 PDF（所需质量）

绘图作为元文件复制到剪贴板并粘贴到.docx文档中

弯曲的线条，与预期不同的点大小。即使将 .docx 文档另存为 PDF，这些美学缺陷仍然存在
