我有以下数据框(抱歉没有提供dput的示例,当我在此处粘贴时,它似乎不适用于列表):

现在,我想创建一个新列y是需要之间的区别mnt_ope,并ref_amount为每一个元素ref_amount.结果将是每行中具有与相应值相同的元素数量的列表ref_amount.

779.95, 779.95, 2502.34, 810.89, 810.89, 810.89, 810.89, 810.89
), ref_amount = list(c(500, 500), c(500, 500), c(771.07, 770.26, 
770.26), c(771.07, 770.26, 770.26), c(771.07, 770.26, 770.26), 
    c(771.07, 770.26, 770.26), c(771.07, 770.26, 770.26), c(771.07, …
