Re: [R] package(moments) issue

Another bad case is > moments::anscombe.test(rep(c(1,1.1),length=35)) Error in if (pval > 1) pval <- 2 - pval : missing value where TRUE/FALSE needed I haven't checked the formulas carefully, but I suspect the problem is from taking the cube root of a negative number in z <- (1

Re: [R] package(moments) issue

moments::anscombe.test(x) does give errors when x has too few values or if all the values in x are the same > moments::anscombe.test(c(1,2,6)) Error in if (pval > 1) pval <- 2 - pval : missing value where TRUE/FALSE needed > moments::anscombe.test(c(2,2,2,2,2,2,2,2)) Error in if (pval > 1) pval

I'm sure I don't know the answer, but I'll hazard a guess why no one has responded in 3 hours. Generally persons submit question to Rhelp with some code and data (or at least a description of the data). Questions about theory are considered off-topic although sometimes addressed if there seems
