我有以下代码
Error in plot.window(xlim, ylim, "", ...) : need finite 'ylim' values
In addition: Warning messages:
1: In n * h : NAs produced by integer overflow
2: In breaks[-1L] + breaks[-nB] : NAs produced by integer overflow
然后我收到了警告
hist(as.numeric(as.POSIXct(a,format="%Y-%m-%d %H:%M:%S", tz = "GMT")), breaks=10)
为什么会这样？
即使有以下
Warning messages:
1: In n * h : NAs produced by integer overflow
2: In breaks[-1L] + breaks[-nB] : NAs produced by integer overflow
我仍然收到错误

此外，还有一个小问题：
a=c(a, ...)也就是说，为什么R控制台不会将其视为完整列表（尽管更长），而不是等待输入更多？我必须执行fileSystems来连接两个列表。
