label variable for stargazer extraction

Question

I am using stargazer to extract some regression tables in latex. I would to know if it exists a way to label variables once for all without having to re-define it through "covariate.labels = ..." every time. I tried the library expss (and Hmisc), such as:

library(expss)
library(stargazer)

df <- data.frame(replicate(2,sample(0:1,100,rep=TRUE)))

df = apply_labels(df,
                  X1 =  "label x1",
                  X2 = " label x2")

ols <- lm(formula = X1 ~ X2,
          data= df)

stargazer(ols, 
          # covariate.labels = NULL, 
          title = "Regression Results",
          label = "tab:test",
          out="test.tex")

without success... any suggestion?

Solution with expss use_labels:

library(expss)
library(stargazer)

df <- data.frame(replicate(2,sample(0:1,100,rep=TRUE)))

df = apply_labels(df,
                  X1 =  "label x1",
                  X2 = " label x2")

ols <- use_labels(df, lm(formula = X1 ~ X2))

res <- stargazer(ols, 
          # covariate.labels = NULL, 
          title = "Regression Results",
          label = "tab:test",
          out="test.tex")

# quick and dirty workaround for removing backticks  
remove_backticks = function(text){
    text = gsub("([^A-z]+)`", "\\1", text, perl = TRUE)
    text = gsub("`([^A-z]+)", "\\1", text, perl = TRUE)
    text = gsub("(^`)|(`$)", "", text, perl = TRUE)
    text
}


res = remove_backticks(res)

writeLines(res, "test.tex")
