4, 5, 6.5, 5.5)), .Names = c("MEMORY1", "MEMORY2", "MEMORY3", 
"MEMORY4", "MEMORY5", "MEMORY6", "MEMORY7", "MEMORY8"), row.names = c(NA, 
20L), class = "data.frame")

abils = ncol(rankings)
R = Rgen(2, hyp = NULL, abils)
AllKendall(ranking, R)

当我运行上面的代码时，我收到一条错误消息Error in matrix(0, nrow = N, ncol = n.seq) : non-numeric matrix extent。我读了一些其他相关的帖子，似乎问题是nrow = N不是数字。是什么导致了这种情况发生，我该如何解决？

Answer 1

如果你看一下?AllKendall中的例子，你的“序列集”似乎应该是一个矩阵（看看他们有一个排名列表然后他们rbind他们在一起？）

为此，请尝试

AllKendall(do.call(rbind, R), do.call(rbind, rankings))
# for some reason if you put it the other way round there is an error

结果是一个矩阵，output[i, j]是i中序列R与j中序列rankings的距离。

R：矩阵中的错误（0，nrow = N，ncol = n.seq）：非数字矩阵范围
