R 如何更改向量的某些元素

我有一个数字向量

x

和另一个数字向量

y

x <- c(0.1,0.3,0.2,0.3,0.12,0.1,0.24,0.05,
     0.03,0.22,0.04,0.003,0.21,0.11,0.44,0.52)

y <- c(0.25,0.054,0.09,.0.93,0.23)

我希望仅使用

x

中元素的位置来完成此操作，我希望通过y的位置进行更改，以便获得

x <- c(0.1,0.3,0.25,0.3,0.054,0.09,0.24,0.05,
       0.93,0.22,0.04,0.003,0.21,0.23,0.44,0.52)

x@Barnaby：在旁注中，您可以将要更改的位置存储在另一个向量中，例如
z-Hmm，编辑日志很奇怪。。。在我的工作中，我肯定没有从vector改为data.frameedit@DavidArenburg，它走了另一条路…从数据帧到向量。@RichardScriven，日志上说我把它从向量改成了data.frame，而我唯一做的事情就是把代码行加引号。不知道这是怎么发生的
x <- c(0.1,0.3,0.25,0.3,0.054,0.09,0.24,0.05,
       0.93,0.22,0.04,0.003,0.21,0.23,0.44,0.52)

x <- replace(x, (3,5,6,9,14), (0.25,0.054,0.09,.0.93,0.23))

> x <- c(0.1, 0.3, 0.2, 0.3, 0.12, 0.1, 0.24, 0.05,
         0.03, 0.22, 0.04, 0.003, 0.21, 0.11, 0.44, 0.52)
> y <- c(0.25, 0.054, 0.09, 0.93, 0.23)

> x[c(3, 5, 6, 9, 14)] <- y
> x
