我有一个这样的列表：

> ascii
  [1] "\033" "\032" "\032" "\032" "\032" "\032" "\032" "\032" "\032" "\032"

[231] "\032" "\032" "\032" "\032" "\032" "\032" "\032" "\032" "\032" "\032"
[241] "\032" "\032" "\032" "\032" "\032" "\032" "\032" "\032" "\032" "\032"
[251] "\032" "\032" "\032" "\032" "\032" "\032"

我想在此列表中写入特定的 ascii 字符（此列表称为 ascii）。例如，我想要一个空格“”，您可以在其中看到“\032”。为此，我这样做： ascii[1:32] <- "\032"... 但这会将 "\032" 准确写入这些位置...带有一些字符，例如 "\045" 它可以工作.. .

不要说我请做 ascii[1:32] <- " "，因为我想在列表中介绍其他 ascii 字符，而且我写数字比写字符更好...

非常感谢！

编辑：更新

R 只使用数字。所以例如

myascii<-c(65,66,67)

rawToChar(as.raw(myascii))

给ABC

所以你所要做的就是在修改数组时使用 66 而不是 "\066"
