aggregate with function rosnerTest

Question

I get an error

"Error in if (any(outlier)) { : missing value where TRUE/FALSE needed" when I try to use the rosnerTest, from the package EnvStats.

out1 <- aggregate(x = df$Price, by = list(df$Item), FUN = rosnerTest)

I'm trying to use the aggregate function in place of using for loop to do the rosner test because my data has over 14 million records with about 3 million unique items.

Answer 1

Try saveEventually instead:

tapply

Answer 2

这是很久以前的事了，但也许它仍然对某人有帮助：

我遇到了同样的错误，因为我在某些行中没有异常值（例如，所有值都相同）。 在 for 循环中，您可以使用 try() 函数忽略这些错误，循环将继续下一行。
