创建命名向量，其中名称与csv文件中的GO id相关联不起作用。

我错过了什么？

提前谢谢。

如果您想要一个矢量作为结果，也许您可以尝试将您的值和名称（第1列）强制转换为字符。

data <- read.delim("~/GOmapping.tsv", sep = '\t')
geneID2GO <- as.character(data[,2])
names(geneID2GO) <- as.character(data[,1])
head(geneID2GO)
                    sp0000005                          sp0000006                          sp0000007 
                  "GO:0003723"                       "GO:0016021" "GO:0003700,GO:0006355,GO:0043565" 
                     sp0000016 
                  "GO:0046983"

或者，您可以按如下方式显示结果：

cbind(geneID2GO)
          geneID2GO                         
sp0000005 "GO:0003723"                      
sp0000006 "GO:0016021"                      
sp0000007 "GO:0003700,GO:0006355,GO:0043565"
sp0000016 "GO:0046983"

从csv文件创建命名向量不起作用
