Question

我的R中的data.frame看起来像这样

> mydata=data.frame(id=c(rep("gene1",3),rep("gene2",4),rep("gene3",1),rep("gene4",2)),description=c(rep("protein1",3),rep("protein2",4),rep("protein3",1),rep("protein4",2)),type=c(rep("coding",10)),name=c("nucleus","binding","ribosome","transcription factor","regulation of transcription","DNA","sequence-specific binding","hydrolase","transporter","ion transport"),definition=paste(rep("blabla",10),1:10))
> mydata
  id     description   type                        name definition
1  gene1    protein1 coding                     nucleus   blabla 1
2  gene1    protein1 coding                     binding   blabla 2
3  gene1    protein1 coding                    ribosome   blabla 3
4  gene2    protein2 coding        transcription factor   blabla 4
5  gene2    protein2 coding regulation of transcription   blabla 5
6  gene2    protein2 coding                         DNA   blabla 6
7  gene2    protein2 coding   sequence-specific binding   blabla 7
8  gene3    protein3 coding                   hydrolase   blabla 8
9  gene4    protein4 coding                 transporter   blabla 9
10 gene4    protein4 coding               ion transport   blabla 10

我需要像这样转换它

> mydata2=data.frame(id=c("gene1","gene2","gene3","gene4"),description=c("protein1","protein2","protein3","protein4"),type=c(rep("coding",4)),name=c("nucleus,binding,ribosome","transcription factor,regulation of transcription,DNA","sequence-specific binding","hydrolase,transporter,ion transport"),definition=paste(rep("blabla",4),c(3,7,8,10)))
> mydata2
    id description   type                                                 name   definition
1 gene1    protein1 coding                             nucleus,binding,ribosome   blabla 3
2 gene2    protein2 coding transcription factor,regulation of transcription,DNA   blabla 7
3 gene3    protein3 coding                            sequence-specific binding   blabla 8
4 gene4    protein4 coding                  hydrolase,transporter,ion transport   blabla 10

我尝试了几个功能

dcast
reshape2
spread

但我没有得到我需要的东西。例如，对于reshape2，它为$ name中的每个不同条目创建一个新列。

有人可以帮忙吗？非常感谢

PS：第一篇文章，我希望编辑没问题，原谅我否则

这对你有用吗？它按ID，描述和类型拆分数据。对于每个子集，它将名称粘贴在一起并选择最后一个定义。

var options = new ConfigurationOptions
            {
                EndPoints = { "your_endpoint:port" },
                Proxy = Proxy.Twemproxy
            };

            ConnectionMultiplexer redis = ConnectionMultiplexer.Connect(options);

如何根据另一列值连接数据框列中的不同行？
