如何从 biglm 对象中提取公式?我已经尝试过 as.formula() 函数,但它没有返回我期望的结果。示例:

m1 = lm(Fertility ~ Agriculture + Examination + Education + Catholic + Infant.Mortality, data=swiss)
as.formula(m1) # returns only the formula expression (that's what I want!)
# returns: Fertility ~ Agriculture + Examination + Education + Catholic + Infant.Mortality

library(biglm)
m2 = biglm(Fertility ~ Agriculture + Examination + Education + Catholic + Infant.Mortality, data=swiss)
as.formula(m2) # returns many things, but I want only the formula expression

最佳答案

您可以使用术语公式:

formula(terms(m2))

Fertility ~ Agriculture + Examination + Education + Catholic +
Infant.Mortality
