如何在cbind/aggregate中重命名变量？

我有以下代码行：

inc_ag <- aggregate(cbind(inc2$SUM_violent, inc2$SUM_nonviolent) ~ District + MicrozoneID + Period, data = inc2, FUN = sum, na.rm=TRUE)

        District          MicrozoneID                    Period V1 V2
1   Northwestern    Northwestern: 61A   2019-02-06 - 2019-03-06 3   1
2   Northwestern    Northwestern: 61B   2019-02-06 - 2019-03-06 1   0
3   Northwestern    Northwestern: 61D   2019-02-06 - 2019-03-06 3   2
4   Northwestern    Northwestern: 62A   2019-02-06 - 2019-03-06 0   2

下面是一个

dplyr

解决方案：

inc_ag <- aggregate(cbind(inc2$SUM_violent, inc2$SUM_nonviolent) ~ District + MicrozoneID + Period, data = inc2, FUN = sum, na.rm=TRUE) %>%
rename(violentIncidents = V1, nonviolentIncidents = V2)

inc_ag%
重命名（暴力事件=V1，非暴力事件=V2）

无需引用参数名称：它们不是字符串。

structure(list(District = c("Northwestern", "Northwestern", "Northwestern", 
"Northwestern"), MicrozoneID = c("Northwestern: 61A", "Northwestern: 61B", 
"Northwestern: 61D", "Northwestern: 62A"), Period = c("2019-02-06 - 2019-03-06", 
"2019-02-06 - 2019-03-06", "2019-02-06 - 2019-03-06", "2019-02-06 - 2019-03-06"
), V1 = c(3, 1, 3, 0), V2 = c(1, 0, 2, 2)), class = "data.frame", row.names = c(NA, 
-4L))

inc_ag <- aggregate(cbind(inc2$SUM_violent, inc2$SUM_nonviolent) ~ District + MicrozoneID + Period, data = inc2, FUN = sum, na.rm=TRUE) %>%
rename(violentIncidents = V1, nonviolentIncidents = V2)
