使用InkScape在R图中裁剪线条

Question

我使用以下代码在R中创建了一些图表。数据文件粘贴在下面。我无法在此处创建要上传的图片文件，但可以使用此代码，下面提供的数据和InkScape说明重新创建图形。我正在使用Windows。

c.low <- read.csv('c.low.csv', header = TRUE, stringsAsFactors = FALSE, na.strings = "NA")
e.high <- read.csv('e.high.csv', header = TRUE, stringsAsFactors = FALSE, na.strings = "NA")

my.plot <- 'small_plot_with_inkscape_to_crop_lines.svg'

library(Cairo)
CairoSVG(my.plot, onefile = TRUE, pointsize = 12, width=6, height=9, bg="white")
par(mfrow=c(3,2), oma=c(0.5,0.5,0.5,0.5), cex.lab=1.0, asp=1)

plot(c.low$TT, c.low$point, xlab = 'TT', ylab = 'C', type = 'l', col = 'green', lwd = 2, lty = 1,
     ylim = c(0, (max(c.low$point)+0.1)), cex.lab = 1.5)
     lines(c.low$TT,  c.low$lower95CI, type = 'l', col = 'brown', lwd = 2, lty = 3)
     lines(c.low$TT,  c.low$upper95CI, type = 'l', col = 'brown', lwd = 2, lty = 3)

plot(e.high$TT, e.high$point, xlab = 'TT', ylab = 'E', type = 'l', col = 'green', lwd = 2, lty = 1,
     ylim = c(0, (max(e.high$point)+0.1)), cex.lab = 1.5)
     lines(e.high$TT, e.high$lower95CI, type = 'l', col =  'blue', lwd = 2, lty = 3)
     lines(e.high$TT, e.high$upper95CI, type = 'l', col =  'blue', lwd = 2, lty = 3)

dev.off()

然后我用svg打开InkScape文件并将文件另存为emf文件。保存emf文件后，我在Convert texts to paths窗口中选择EMF Output。

当我打开emf中的emf文件时，问题是MSWord文件中的某些行超出了绘图框。在R或InkScape中查看时，这些线在图框外不可见。

如何裁剪emf文件中的线条，或者在MSWord中查看时阻止它们在图框外可见？

Answer 1

显然原帖中描述的问题与长期错误有关。我已经能够通过在R内裁剪线条来解决问题。下面我使用grconvertY来标识顶部边框的位置，然后使用ifelse语句将该值以上的元素设置为NA。

人们通常建议使用"usr"来识别顶部边框的位置，但鉴于我在图中创建了两个面板，我无法使用该选项。

后处理后的数字如下所示（在InkScape内进行格式转换后导入PowerPoint [然后保存为jpeg的{​​{1}}）。
