rmarkdown 的 PDF 输出中的边距太宽

Question

我正在尝试更新 rmarkdown 的 pdf 输出的边距。

这是我的代码：

---
title: "Analysis Report "
date: "Last edited `r format(Sys.time(), '%B %d, %Y')`"
geometry: "left=2cm,right=2cm,top=2cm,bottom=2cm"
output:
  pdf_document:
    toc: true
    pandoc_args: [
      "--number-sections",
      "--number-offset=1"
    ]
---
  
```{r setup, include=FALSE}

library(naniar)
library(flexdashboard)
library(ggplot2)
library(rsconnect)
library(leaflet)
library(table1)
library(shiny)
library(DT)
library(readr)
library(kableExtra)
library(flextable)
library(expss)
library(tidyverse)
library(knitr)
library(plotly)
library(magrittr)


dfTab <- structure(list(x = structure(1:4, .Label = c("No, they do not agree", "Yes, they agree", "Unable to contact participant", "Undecided"), 
                                      class = "factor"), Freq = c(1L, 7L, 0L, 0L), lab = c("1 (12.5%)", "7 (87.5%)", "0 (0%)", "0 (0%)")), 
                   row.names = c("No, they do not agree", "Yes, they agree", "Unable to contact participant", "Undecided"
                                                        ), class = "data.frame")

\\```

\newpage

# Sample Graph

```{r, echo=FALSE,out.width='\\textwidth', fig.height = 7, fig.align='center', out.height="80%",out.width="80%"}


plot <- ggplot(dfTab, aes(x=x, y=Freq, fill=x)) +
  geom_bar(width = 1, size = 1, stat = "identity") +
  geom_text(aes(label=lab), vjust = -1)+
  theme_classic() +
  theme(#axis.text.x = element_text(size = 12, colour = "black"),
        axis.line.x = element_line(),
        axis.ticks.x = element_line(),
        #axis.text.y = element_blank(),
        #axis.line.y = element_blank(),
        #axis.ticks.y = element_blank(),
        #axis.text=element_text(size=12),
        axis.title=element_text(size=12,face="bold"),
        panel.grid.major = element_blank(),
        panel.grid.minor = element_blank(),
        legend.position="top",
        legend.title = element_blank())+
  #scale_x_discrete(labels = abbreviate)+
  labs(title="This is the title of the graph", x="", y="Count")


plot

请注意，我在上面代码中的 3 个刻度之前添加了“\”，以便 stackoverflow 编辑器识别我的代码。

反正输出文档是这样的

边距仍然太宽。我的代码有问题吗？我读过我必须在geometry: "left=2cm,right=2cm,top=2cm,bottom=2cm" 中声明边距大小，但它似乎不起作用。非常感谢任何帮助。

让我们尝试通过我为您制作的这个简单示例来解决您的问题。

---
title: "test"

header-includes: 
 \usepackage{geometry}
 \geometry{top=0.75in,left=3in,bottom=0.75in,right=0.80in}
 
output:
  pdf_document

Is it work at your machine - yes or no? \
By me - it works!   \

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

    ```{r pressure, echo=FALSE}
    plot(pressure)
    ``` 

它可以在您的 PC 上正常运行吗？
