如何使用 dplyr::select 而不使用列索引取消选择名为“(Intercept)”的列？

library(dplyr)
library(tibble)

tib<-tribble(~"(Intercept)",~b,
              80,3,
              80,4,
              80,4)

tib[,-1] # works

select(tib,eval(parse(("-(Intercept)")))) # does not work
select(tib,as.name(("-(Intercept)"))) # does not work 
select(tib,-"\(Intercept\)") # does not work

谢谢&亲切的问候

我们需要使用反引号

tib %>% 
    select(-`(Intercept)`)
tib %>% 
    select(`(Intercept)`)
