Similar questions have been raised for other languages: C, sql, java, etc.
但我试图在 R 中做到这一点.
But I'm trying to do this in R.
我有:
ret_series <- c(1, 2, 3)
x <- "ret_series"
如何通过在 x 上调用一些函数/操作来获得 (1, 2, 3)，而不直接提到 ret_series?
How do I get (1, 2, 3) by calling some function / manipulation on x, without direct mentioning of ret_series?
