r - pnorm 函数错误信息（使用 Mac OS）（R 版本为 3.5.2）
问题描述
R 中的 pnorm 函数无法正常工作。对于标准正态分布，pnorm 应小于 1。
> pnorm(1.96)
[1] 1.96 # suppose to be 0.97500
> pnorm(1, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE)
Error in pnorm(1, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE) :
unused arguments (mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE)
