计数r中的变量值

Question

我收集的数据如下：

# Data
df <- data.frame("Hospital" = c("Buge Hospital", "Buge Hospital", "Greta Hospital", "Greta Hospital",
                                "Makor Hospital", "Makor Hospital"),
                 "Period" = c("Jul-18","Aug-18", "Jul-19","Aug-19", "Jul-20","Aug-20"),
                 "Medical admissions" = c(12,56,0,40,5,56),
                 "Surgical admissions" = c(10,2,0,50,20,56),
                 "Inpatient admissions" = c(9,5,6,0,60,96))

df

现在，我确实希望每个月获得总条目，因此，我需要计算每个月变量的总数，并为总计创建另一列。

我试过了，但这不管用

df['totals'] = df [sum(2:5)]

我如何得到一年中每个月每一行的总和？

Answer 1

我想你想要rowSums(df[3:5])。
