Question

R的stargazer包有两个参数，covariate.labels和column.labels，用于自定义表格文本。

我想在这些参数中使用希腊语或数学表达式。我已经尝试了乳胶文本的标准语法，我尝试过R表达式，如下所示：

covariate.labels = c($\beta_{0}$, $\beta_{1}$)
covariate.labels = c(expression(beta[0]), expression(beta[1]))

我也试过上面的变化，我还没有实现基本的数学符号注释。任何帮助表示赞赏。

Answer 1

covariate.labels需要是一个字符向量。请记住，您需要在R字符串中使用另一个反斜杠来转义反斜杠。

stargazer(mtcars[,1:2],covariate.labels=c("$\\beta_{0}$", "$\\beta_{1}$"))

Answer 2

如果您使用type = "html"进行此操作，则可以use html tags to modify table elements。这对我有用：

model <- lm(mpg ~ cyl, mtcars)

stargazer(model,
         covariate.labels = c("<p>&beta;<sub>0</sub></p>",
                              "<p>&beta;<sub>1</sub></p>"))
