我有一个看起来像这样的数据框:
structure(list(Mash_pear = c(0.192474082559755, 0.679726904159742,
0.778564545349054, 0.573745352397321, 0.56633658385284, 0.472559997318901,

), tRap_pear = c(0.0350096175177328, 0.234255507711743, 0.23714999195134,
0.185536020521134, 0.191585098617356, 0.201402054387186, 0.220911538536031,
0.216072802572045, 0.132247101763063, 0.172753098431029), Beeml_pear = c(0.179209909971615,

0.794652394149651), Mash_pear2080 = c(0.823944540480775, 0.816630852343513,

)), .Names = c("Mash_pear", "tRap_pear", "Beeml_pear", "Mash_pear2080"
), row.names = c("Aft1", "Alx3_3418.2", "Alx4_1744.1", "Arid3a_3875.1_v1_primary",
"Arid3a_3875.1_v2_primary", "Arid3a_3875.2_v1_primary", "Arid3a_3875.2_v2_primary",
"Arid5a_3770.2_v1_primary", "Arid5a_3770.2_v2_primary", "Aro80"
), class = "data.frame")
现在我有了对这些分数进行排名的想法,但是每一列都应该单独排名,并保持行名不变。因此,我尝试逐个提取所有列并对其进行排序。尝试订购 1 列时出现我遇到的问题。即我的数据框消失并成为数值向量,正如我已经指出的那样,我需要数据框(行名)保持原样,仅排序。我现在正在处理的代码在这里:
rowname<-rownames(pearframe)
col1<-subset(pearframe, select=1)[order(pearframe),]
col2<-subset(pearframe, select=2)[order(pearframe),]
col3<-subset(pearframe, select=3)[order(pearframe),]
col4<-subset(pearframe, select=4)[order(pearframe),]
这将删除我的行名和原始数据框结构。这使得我无法对我的数据进行排名。所以实际的问题是:我如何对每列的数据帧进行排序/排序并创建 4 个新帧,每个帧有 1 个有序列。最终我想要一个表格,其中包含每个排名框架的行名和分数。
