Question

我见过this，但我想知道为什么它不适合我的情况

我有这个载体：

function rechnung()
{
    var x = document.getElementById("range3").innerHTML;
    alert(x);
}

然后我试图找到大于0的最小值num<-c(0.000000, 4.220190, 1.421267, 1.004988, 5.060632, 1.100000, 3.744329, 5.728001, 4.707441, 4.100000, 5.200961, 5.060632, 2.282542 ,1.676305, 0.509902, 0.781025, 2.968164, 5.916925, 5.235456, 5.371220) 所以我有

0.509902

但它给了我

which.min(num > 0)

索引1

Answer 1

我们可以使用select BillNumber, BillDate, (select CustomerName from tblCustomer where tblCustomer.CustomerId = tblBillHeader.CustomerId) as CustomerName, (Select ProductId from tblBillDetail where tblBillHeader.BillNumber = tblBillDetail.BillNumber) as ProductId from tblBillHeader;替换小于或等于0的值，并使用NA

which.min

或稍微紧凑的方式

i1 <- which.min(replace(num, num<=0, NA))
i1
#[1] 15

查找最小值大于0的索引
