在代码中看起来像这样（尝试过滤一些变量）。
library(magrittr)
d.cty <- filter(ann2012full, agglvl_code==70)%.%
select(state, county, abb, avg_annual_pay, annual_avg_emplvl)%.%
mutate(wage=Discretize(avg_annual_pay),
empquantile=Discretize(annual_avg_emplvl))

我认为字段名称很好，我认为整体数据很好，所以我不确定这里发生了什么。我可能只是错过了一些简单的东西，但我无法看到它。任何人都对这里发生的事情有任何见解？感谢。
