按中位数而非平均数订购价值

Question

我想更改下面的函数，以便value根据中值而非平均值重新排序。使用mean更改median无效

sign.m$miRNA <- with(sign.m, reorder(miRNA,as.numeric(as.character(value)),mean))

> head(sign.m)
             miRNA variable  value
1   hsa-miR-99a-5p      100  -1.37
2 hsa-miR-92a-1-5p      100   3.11
3     hsa-miR-9-5p      100  -3.60
4   hsa-miR-877-5p      100   2.08
5     hsa-miR-7-5p      100   3.37
6  hsa-miR-642a-5p      100  -5.10
