在 R 中使用 texreg()，如何在生成的 LaTeX 表中添加一行

Question

How can I add to a table a (text or empty) line in the middle of a LaTeX tabular environment generated with texreg() from a regression result. In the example below, I would like to add the empty line and a line with Subtitle for Coefficients Below . The Coefficients 1 - 4 are from the regression and are selected and sorted using custom.coef.map = in texreg() .

Variable	Model 1
Coefficient of Variable 1	999.99
Coefficient of Variable 2	999.99
Subtitle for Coefficients Below
Coefficient of Variable 3	111.11
Coefficient of Variable 4	111.11

Thanks for any suggestions!

Use the argument groups = list("Subtitle for coefficients below" = 3:4) or similar.
