Question

我在R中有一个data.frame，有十列，但只有三列感兴趣。我需要根据“ID”，“test”和“result”列中的数据创建两个新列。逻辑相当简单......

首先会创建两个新列，正面和负面。
如果特定ID的结果列的值为“正”，则测试字段应出现在刚刚创建的新“正”列中，而“否定”则相反
如果在多行中找到ID（即重复ID），则应为每个行的“test”值创建一个数组。
该数组应该放在新的Positive或Negative行中，具体取决于该ID的'result'列。

这就是数据的样子..

dput(data)

Answer 1

不确定最后两点是什么意思，但如果我理解正确的话，第一部分相当容易：

test<-data.frame(test=c("bordetella","pneumocystis","adenovirus"),result=c("positive","negative","positive"))
test$positive<-ifelse(test$result=="positive",as.character(test$test),"")
test
test         result   positive
bordetella   positive bordetella
pneumocystis negative           
adenovirus   positive adenovirus

这是你想要的吗？

循环遍历R中的data.frame以基于逻辑创建变量
