如何抑制输出文件中的stargazer()信息

I'm using the stargazer package to output an R dataframe as latex code:

我使用stargazer包输出一个R dataframe作为乳胶代码:

library(stargazer)

stargazer(mtcars)

And this is the output

这是输出

Note the output includes two lines of latex comments (top two lines, beginning %). How can I stop the top two lines (beginning %) from being outputted?

注意，输出包含两行乳胶注释(前两行，起始%)。我怎样才能阻止前两行(开始%)被输出?

A similar question, but concerning xtable() was asked here: Using table caption on R markdown file using knitr to use in pandoc to convert to pdf

这里提出了一个类似的问题，但与xtable()有关:使用R markdown文件上的表标题，使用knitr在pandoc中将表标题转换为pdf

2 个解决方案

#1

From version 4.0 onwards (available on CRAN now), you can run stargazer with the argument header=FALSE to omit the initial comments in your Latex code ouput.

从4.0版本开始(现在可以在CRAN上使用)，您可以使用参数标头=FALSE运行stargazer，以忽略Latex代码输出中的初始注释。

#2

One could just modify the output directly

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")
}

which gives

这给了
