如何在不考虑无限值的情况下计算 R 中的最大值和最小值?

我的数据具有以下示例的格式(此处为较小比例):

My data has the format of the example below (on a smaller scale here):

a <- c(NaN, Inf, 1, 2, 3, 4, 5)

我知道如果我在 R 中使用:

I know that if I use in R:

min(a, na.rm = TRUE)

或

max(a, na.rm = TRUE)

NaN 将被忽略而不是 Inf，因此在 min(a, na.rm = TRUE) 中的结果是1(因为 na.rm = TRUE 而忽略 NaN)，但结果在 max(a, na.rm =TRUE) 是 Inf.

the NaN will be disregarded but not the Inf, so that in min(a, na.rm = TRUE) the result is 1 (disregarding the NaN because of na.rm = TRUE), but the result in max(a, na.rm = TRUE) is Inf.

有没有办法在 R 中获得向量的最大值和最小值，同时忽略无穷大Inf，以及忽略NaN?

Is there any way to get, in R, the maximum and minimum of a vector and also disregard the infinite Inf, as well as theNaN is disregarded?

感谢您的帮助.
