我有一个数据框(summary_transposed_no_time),我想将其中一列重命名为我存储为值的名称。
summary_transposed_no_time看起来像这样:
| A | B | C | D
------ | ------ | ------ | ------ | ------
area_1 | 0.870 | 0.435 | 0.968 | 0.679
area_2 | 0.456 | 0.259 | 0.906 | 0.467
area_3 | 0.298 | 0.256 | 0.457 | 0.768
area_4 | 0.994 | 0.987 | 0.365 | 0.765
我的值称为test,它被设置为“B”,所以我尝试使用以下代码而没有运气:
summary_transposed_no_time <- names(summary_transposed_no_time)[c(test_col)]<-c("test")
欲望输出
| A | test | C | D
------ | ------ | ------ | ------ | ------
area_1 | 0.870 | 0.435 | 0.968 | 0.679
area_2 | 0.456 | 0.259 | 0.906 | 0.467
area_3 | 0.298 | 0.256 | 0.457 | 0.768
area_4 | 0.994 | 0.987 | 0.365 | 0.765
答案 0 :(得分:2)
我认为您需要(我已将summary_transposed_no_time
替换为x
)
names(x)[match(test_col, names(x))] <- "test"
x <- trees[1:5, ]
# Girth Height Volume
#1 8.3 70 10.3
#2 8.6 65 10.3
#3 8.8 63 10.2
#4 10.5 72 16.4
#5 10.7 81 18.8
names(x)[match("Girth", names(x))] <- "test"
# test Height Volume
#1 8.3 70 10.3
#2 8.6 65 10.3
#3 8.8 63 10.2
#4 10.5 72 16.4
#5 10.7 81 18.8
