我想知道为什么cat功能在R中打印希腊字母但是当我在停止功能中使用时它看起来不像希腊字母
这是代码
al1 <- paste0(intToUtf8(945),1,sep='')
al2 <- paste0(intToUtf8(945),2,sep='')
msg <- paste0(al2," must be between 0 and ",al1)
stop(msg)
Error: a2 must be between 0 and a1
cat(msg)
α2 must be between 0 and α1
你可以在停止时看到它看起来像“a”？
这是sessioninfo
> sessionInfo()
