我想将报表中的数字格式化为有效数字,但保持尾随重要的零并正确格式化大数字

例如,数字c(10.00001,12345,1234.5,123.45,1.2345,0.12345)到3位有效数字应该是10.0,12300,1230,123,1.23,0.123但是我用不同的方法得到了不同的结果(并且似乎没有一个通用的工作.

> numbers<-c(10.00001,12345,1234.5,123.45,1.2345,0.12345)
> for(n in seq(numbers)){
+   print(signif(numbers[n],digits=3))
+   print(format(numbers[n],digits=3))
+   print(formatC(numbers[n], digits=3,format="fg"))
+   print(formatC(numbers[n], digits=3,format="fg", flag="#"))
+   }
