Get `chisq.test()$p.value` for several groups using `dplyr::group_by()`

Question

I\'m trying to conduct a chi square test on several groups within the dplyr frame. The problem is, group_by() %>% summarise() doesn\'t seem to do t

Answer 1

In dplyr you can generally just use unquoted variable names to access the relevant columns, whether you're in a groupby or otherwise. So removing the .$ accessors from .$partido and .$genero which are not needed I get:

foo %>% 
    group_by(GM) %>% 
    summarise(pvalue= chisq.test(partido, genero)$p.value) 

# A tibble: 2 × 2
        GM    pvalue
         
1     Bajo 0.9004276
2 Muy bajo 0.4777095
