如何在输出文件中抑制stargazer（）信息

我使用

stargazer

包将R数据帧输出为latex代码：

library(stargazer)

stargazer(mtcars)

这就是输出

\hline \\[-1.8ex] 
\normalsize 
\end{tabular} 
\end{table} 

注：输出包括两行latex注释（前两行，开头%）。如何停止输出前两行（开始%）

这里提出了一个类似的问题，但与xtable（）有关：

可以直接修改输出

mod_stargazer <- function(...){
  output <- capture.output(stargazer(...))
  # The first three lines are the ones we want to remove...
  output <- output[4:length(output)]
  # cat out the results - this is essentially just what stargazer does too
  cat(paste(output, collapse = "\n"), "\n")
}

从4.0版开始（现在可在CRAN上获得），您可以使用参数header=FALSE运行stargazer，以忽略Latex代码输出中的初始注释
