r - 计算 dplyr 中选定列的摘要
问题描述
我有一个 df,其中包含国家名称、病例数(covid)和国家/地区的人口数量。所以我想总结一下案件的数量。问题是每一行的人口数量都是相同的,因此不应将它们相加。那么我怎样才能只总结案例列。
cases_names_pop <- cases_names_pop %>% group_by(countriesAndTerritories) %>% summarise_all((sum))
这是我使用的数据:
structure(list(countriesAndTerritories = c("Afghanistan", "Afghanistan",
"Afghanistan", "Afghanistan", "Afghanistan", "Afghanistan", "Afghanistan",
"Afghanistan", "Afghanistan", "Afghanistan", "Afghanistan", "Afghanistan",
"Afghanistan", "Afghanistan", "Afghanistan", "Afghanistan", "Afghanistan",
