我有以下multiset X,其中我想找到所有数字之间的距离。有没有办法将它集成到FOR LOOP中,这样如果给我一个不同大小的多重集,我就不必像下面那样手动完成它?

这个例子的最终答案是[0,2,2,3,3,4,5,6,7,8,10](已排序)

X=c(0,10,8,3,6)
L=length(X)
print(L)

##for(i in seq(from=1, to=L )){}

print(abs(X[1]-X[2]),  abs(X[1]-X[3]),
    abs(X[1]-X[4]),  abs(X[1]-X[5]),
    abs(X[1]-X[6]),  

    abs(X[2]-X[3]), abs(X[2]-X[4]),
    abs(X[2]-X[5]),  abs(X[2]-X[6]),


    abs(X[3]-X[4]),  abs(X[3]-X[5]),
    abs(X[3]-X[6]),  


    abs(X[4]-X[5]), abs(X[4]-X[6]),


    abs(X[5]-X[6])  

        )

您可能会将此向量视为列向量并应用dist

sort(dist(X))
# [1]  2  2  3  3  4  5  6  7  8 10
