R：如何用group_by()计算一个变量占另一个变量的比例？

Question

我想用group_by显示每个教育程度（变量：edattain）在变量：sex.

内的比例

至此我计算出edattain的比例如下：

india04_new4 %>%
mutate(tot = sum(perwt, na.rm = T)) %>%
group_by(edattain) %>%
summarise(share = sum(perwt, na.rm = T)/first(tot))

如何显示变量内的比例：sex？

Answer 1

尝试以下操作：

result <- india04_new4 %>%
            group_by(sex, edattain) %>%
            summarise(share = sum(perwt, na.rm = TRUE)) %>%
            mutate(share = share/sum(share))
