如何将很长的字符串分配给 r 中的变量?
以下工作正常
testVar <- "test;test;"
但以下在 RStudio 控制台中给出了一个奇怪的+。
testVar <- "test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test;test

当我点击Esc 按钮并打印testVar 时,它只打印test;test;
【问题讨论】:
-
@d.b 你做了什么?虽然我认为 akrun 是对的...太快 ENTER 推
-
@Sotos,复制第二行代码并在 R 中运行它。任何长字符串也会发生这种情况:
x = "VERY LONG STRING" -
@d.b 我也做了同样的事情,它工作正常。
nchar(testVar) #[1] 11760 -
对了,RStudio -- 已回答。
