Register extraline macros to be used in etable
extraline_register(type, fun, alias)
type |
A character scalar giving the type-name. |
fun |
A function to be applied to a |
alias |
A character scalar. This is the alias to be used in lieu of the type name to form the row name. |
You can register as many macros as you wish, the only constraint is that the type name should not conflict with a fitstat
type name.
# We register a function computing the standard-deviation of the dependent variable my_fun = function(x) sd(model.matrix(x, type = "lhs")) extraline_register("sdy", my_fun, "SD(y)") # An estimation data(iris) est = feols(Petal.Length ~ Sepal.Length | Species, iris) # Now we can easily create a row with the mean of y. # We just "summon" it in a one-sided formula etable(est, extraline = ~ sdy) # We can change the alias on the fly: etable(est, extraline = list("_Standard deviation of the dep. var." = ~ sdy))
