我想为同一组变量生成许多表。我使用精彩的R包compareGroups和Hmisc来分配变量标签,这样我就不必为每个表更改变量名。一些变量名称包括乳胶数学模式,但这给了我一个错误,因为compareGroups导出$that$
,如下所示:\$that\$
。这是一个最小的例子:
# assigning Hmisc label includinc math mode in $$
library(Hmisc)
label(mtcars$mpg) <- "[$\\frac{miles}{gallon}$]"
# descriptive table of mpg by am
library(compareGroups)
tab <- createTable(
compareGroups(data = mtcars,
am ~ mpg)
)
# in createTable, the variable name looks fine
tab
# when exported to latex, a \ is inserted before each $
export2latex(tab)
有没有办法避免在export2latex之前插入\?或者任何解决方法?

这是一种使用pixiedust
生成表格的变通方法。 pixiedust
可以选择&#34;清理&#34;通过Hmisc::latexTranslate
的单元格内容。默认情况下,此选项已关闭。
解决方案以Rmd文件形式提供

```{r, include = FALSE}
library(Hmisc)
library(compareGroups)
library(broom)
library(magrittr)
library(pixiedust)
```
```{r}
label(mtcars$mpg) <- "[$\\frac{miles}{gallon}$]"
# descriptive table of mpg by am
tab <- createTable(
compareGroups(data = mtcars,
gear ~ mpg + qsec)
)
tab_df <-
tab$descr %>%
tidy()
tab_head <-
c("", attr(tab, "ylevels"), "p.overall",
"", sprintf("N=%s", tab$avail[1, -c(1, (ncol(tab$avail) - 0:1))]), "") %>%
matrix(nrow = 2,
byrow = TRUE) %>%
tidy %>%
setNames(names(tab_df))
dust(tab_df,
float = FALSE) %>%
redust(tab_head, part = "head") %>%
medley_bw()
```
如果您希望更轻松地触摸它,可以扩展dust
方法以包含dust.createTable
方法(这是原始的,我还没有考虑过所有用例,但是例如)
dust.createTable <- function(object, ...){
obj_df <-
object$descr %>%
broom::tidy()
obj_head <-
c("", attr(object, "ylevels"), "p.overall",
"", sprintf("N=%s", object$avail[1, -c(1, (ncol(object$avail) - 0:1))]), "") %>%
matrix(nrow = 2,
byrow = TRUE) %>%
broom::tidy() %>%
stats::setNames(names(obj_df))
pixiedust::dust(obj_df) %>%
pixiedust::redust(obj_head, part = "head")
}
compareGroups(data = mtcars,
gear ~ mpg + qsec) %>%
createTable() %>%
dust()
compareGroups(data = mtcars,
gear ~ mpg + qsec + wt) %>%
createTable() %>%
dust()

我收到了来自compareGroups论坛(link)的消息,并提供了简单的解决方案。您也可以替换&#34; \ $&#34;用&#34; $&#34;使用sub
函数:
tab <- export2latex(tab)
sub("\\$","$",
tab,
fixed=TRUE,
perl=FALSE)
