我正在尝试使用r markdown
,kable
和kableExtra
输出乳胶表。我需要使用条件逻辑通过cell_spec将颜色添加到表中。但是在pdf输出中,它显示的乳胶代码如下;
如果我在escape = false
中添加kable()
,则会出现以下错误,
!缺少$。 $ l.142 sepal_ length&sepal_width&petal_length&petal_width&Species \这是您使用的TeX内存量:14185个字符串 492970 208670个字符串中的3125261 323511个单词中的一个 内存不足3000000 17834个多字符控制序列 15000 + 200000 23725个字词,用于40种字体,总3000000 对于8191中的9000 1141断字例外 41i,9n,38p,1027b,272s个堆栈位置 5000i,500n,10000p,200000b,50000s
我是rmarkdown
和latex的新手,请帮助我解决问题。谢谢。
这是我的rmd文件代码:

title: "Iris Data Table"
output: pdf_document
header-includes: \usepackage [table]{xcolor}
geometry: margin = 1cm
params:
n: NA
datafile: "//ad.monash.edu/home/User076/vbed0001/Documents/IRIS.csv" #always set the absolute full path

```{r, echo=FALSE, message=FALSE}
d <- read.csv(params$datafile, header = TRUE, sep = ",")
# this uses to remove the warning messages from the pdf file
library(memisc, warn.conflicts = FALSE, quietly=TRUE)
# the package order is important, always kableExtra at the top
#options(kableExtra.latex.load_packages = FALSE)
library(kableExtra)

library(devtools)
options(knitr.table.format = "latex")
if(params$n == "set"){
dtset <- d %>% filter(Species == "setosa")
dtset <- d %>% filter(Species == "setosa")
dtset %>%
mutate(
sepal_length = cell_spec(sepal_length,format = "latex",background = (ifelse(sepal_length>4.5,"#D3D3D3","#ff0000")))
)%>%
kable(format = "latex",caption = "Setosa Table")%>%
kable_styling(position = "center",bootstrap_options = "bordered")
}
```

此错误是由于数据框中带有下划线“ _”引起的。在这种情况下,列名称包含下划线。在TeX中,此符号用于在数学环境中设置下标。这就是为什么在普通文本中使用时必须转义(\_
)的原因。删除,转义或将下划线替换为例如
names(data) <- gsub("_", "", names(data)) # remove
names(data) <- gsub("_", "\\_", names(data)) # escape
names(data) <- gsub("_", " ", names(data)) # replace with space

就我而言,我需要从数据块名称中删除下划线。
例如,这有效:
const data = [{"abc":{"companyCity":"Cupertino","conpanyName":"Apple"}},{"def":{"companyCity":"Mountain View","conpanyName":"Google"}}]
const result = data.flatMap(Object.values)
console.log(result)
但这不起作用:
```{r summaryTableBaseline, results='asis', echo=FALSE}
summaryTableBaseline %>%
kable(col.names = c("Docker Image", "Min", "Mean", "Median", "Max"),
caption = "Baseline Benchmark") %>%
kable_styling()
```
