我一直在尝试使用 R Markdown 创建一些 PDF 报告。我很难正确布局。基本上，我需要在同一行上有一个 KableExtra 创建的表（数据框）和一个 ggplot 图。我探索了一些网格包，但无法让它工作。
这是我的代码：
---
title: "Untitled"
author: ""
date: "14 June 2018"
output: pdf_document
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(knitr)
library(reshape2)
library(dplyr)
library(kableExtra)
```
## R Markdown
```{r chart, echo=FALSE}
Years <- c("2016","2016","2016","2016",
"2017","2017","2017","2017")
Quarters <- c("Q1","Q2","Q3","Q4",
"Q1","Q2","Q3","Q4")
Series1 <- c("100","200","300","400","500","600","700","800")
Series1 <- as.numeric(Series1)
df <- data.frame(Years,Quarters, Series1)
library(ggplot2)
ggplot(df) +
geom_point(aes(x = Quarters, y = Series1)) +
facet_wrap( ~ Years, strip.position = "bottom",scales = "free_x") +
theme(panel.spacing = unit(0,"lines"), strip.background =
element_blank(),
strip.placement = "outside")
```
```{r table, echo=FALSE}
Table <- dcast(df, Years ~ Quarters, fun.aggregate = sum, value.var =
"Series1")
Table <- Table %>%
kable(format = "latex", caption = "Balances", booktabs = TRUE) %>%
kable_styling(latex_options = c("striped","hold_position","condensed"),
font_size = 10)
Table
```
如果你不强烈依赖kable()我可以提供这个gridExtra解决方案。使用时tableGrob(kable(.))乳胶代码不会以某种方式执行，也许其他人想出了如何在 a 中执行乳胶代码tableGrob().
```{r chart, echo=FALSE, message=FALSE}
df <- data.frame(Years=rep(2016:2017, each=4),
Quarters=rep(paste0("Q", 1:4), 2),
Series1=seq(100, 800, 100))
library(ggplot2)
p1 <- ggplot(df) +
geom_point(aes(x=Quarters, y=Series1)) +
facet_wrap( ~ Years, strip.position="bottom", scales="free_x") +
theme(panel.spacing=unit(0, "lines"),
strip.background=element_blank(),
strip.placement="outside",
aspect.ratio=1) # set aspect ratio
Table <- dcast(df, Years ~ Quarters, fun.aggregate=sum, value.var="Series1")
library(gridExtra)
t1 <- tableGrob(Table, theme=ttheme_minimal(), rows=NULL) # transform into a tableGrob
grid.arrange(p1, t1, nrow=1)
```
