问题描述
我有这个列表:
myList <- list(rnorm(10), rnorm(10), rnorm(10))
names(myList) <- c("one", "two", "three")
$one
[1] -0.07587506 -0.09997924 -0.41846732 1.41542651 -0.58678093 0.56909465 -1.11074541
[8] 1.94663786 0.46381799 -0.11458166
$two
[1] 0.98883679 -0.06305794 -0.78961229 1.21091484 0.19636700 0.27458057 0.12374154
[8] 0.83782946 -0.79627870 0.97675486
$three
[1] 0.67033455 -0.80243815 0.08716750 -2.90455146 -0.02433571 -0.93062428 -0.16886116
[8] -0.60927976 -1.77758270 -1.05033148
我想从列表中删除two和three，并且我想使用两个"和三个"来引用这些元素.我已经尝试过:
I want to remove two and three from the list and I want to refer to these elements using "two" and "three". I've tried:
myList <- myList[[-c("two", "three")]]
...这会导致错误.
...which gives an error.
如何从列表中删除two和three并使用两个"和三个"来引用它们?
How can I remove two and three from the list and refer them using "two" and "three"?
推荐答案
myList[which(names(myList) %in% c("two","three"))] <- NULL
