问题描述

我使用 ggforce 包在多个页面上生成分面图:

 库(ggforce)
$ b $ for(i in 1:6){
ggplot(diamonds)+
geom_point(aes(克拉,价格),alpha = 0.1)+
facet_wrap_paginate(〜cut:clarity,ncol = 2,nrow = 2,page = i)

ggsave(paste0(〜/ diamonds_,i,.pdf))
}

正在生成预期的6个PDF文件:



最简单的方法是在一页pdf中输出6页吗?



我知道这可以通过报告 pdftools 包完成,但我想知道是否有更直接的方法来实现这一点。我希望ggforce为输出提供单页功能,但看起来情况并非如此? 解决方案

你甚至不需要使用 ggsave ,你可以把所有这些图放入一个 pdf 中:

  pdf(〜/ diamonds_all.pdf)
for(i in 1:6){
print (ggplot(钻石)+
geom_point(aes(克拉,价格),alpha = 0.1)+
facet_wrap_paginate(〜cut:净度,ncol = 2,nrow = 2,page = i))


dev.off()


I'm using the ggforce package to generate facetted plots over several pages:

library(ggforce) 

for(i in 1:6){
  ggplot(diamonds) +
    geom_point(aes(carat, price), alpha = 0.1) +
    facet_wrap_paginate(~cut:clarity, ncol = 2, nrow = 2, page = i)

  ggsave(paste0("~/diamonds_", i, ".pdf"))
}

which is generating the expected 6 PDF files:

What is the easiest way have the output in one single pdf with 6 pages?

I understand this can be done with the reports and pdftools packages, but I'm wondering if there's a more direct way to accomplish this. I'd expect ggforce to provide the functionality for the output to be single-paged, but it looks like that's not the case?

解决方案

You don't even need to use ggsave you can put all these plots into one pdf by:

pdf("~/diamonds_all.pdf")
for(i in 1:6){
  print(ggplot(diamonds) +
          geom_point(aes(carat, price), alpha = 0.1) +
          facet_wrap_paginate(~cut:clarity, ncol = 2, nrow = 2, page = i))

}
dev.off()
