我有一个看起来像这样的数据集 -
col1 1 ATOM 1 N ILE A 12 67.611 47.640 52.312 1.00 12.44 N 2 ATOM 2 CA ILE A 12 66.381 47.660 51.520 1.00 25.25 C
它有一个名为col1的列。我想分成12列，我正在使用以下命令 -
try=separate(subset,col1,c("name","S.No","Atom Name","Residue Name","Symbol","Residue Number","X-cor","Y-cor","Z-cor","Uk1","Uk2","Symbol"), sep= " ")
但我继续收到以下错误，我不明白 -
警告消息：3929个位置的值太多：1,2,3,4,5,6， 7,8,9,10,11,12,13,14,15,16,17,18,19,20 ......
它给了我以下输出 -
name S.No Atom Name Residue Name Symbol Residue Number X-cor Y-cor Z-cor Uk1 Uk2 Symbol 1 ATOM 1 N ILE 2 ATOM 2 CA ILE A
任何帮助解决这个问题都非常感谢。谢谢！

应该有更优雅的解决方案。但没有那个图书馆，这就是我所拥有的
tidyr我假设您的数据集名称为data.frame(do.call(rbind, unlist(apply(subset, 1, function(x) strsplit(x, "\\s+")),recursive=FALSE)))
。对于data.frame的每一行，您将其按空格分开，即此部分subset。其余的基本上是将它放在data.frame中。
刚刚想出来，在您的代码中只需将strsplit(x, "\\s+"))替换为sep= " "即可。
sep= "\\s+"至少在空格上陈述，而你的\\s+恰好是一个空格。
答案 1 :(得分：0)
我遇到了同样的问题
解决方案： - 不要使用＆＃34; sep＆＃34;如果你想分割由＆＃34;。＆＃34;
连接的两个字符（或任何东西）参考：检查单独（）
文档中提供的示例> df <- data.frame(x = c(NA, "a.b", "a.d", "b.c"))
> df %>% separate(x, c("A", "B"))
A B
1 <NA> <NA>
2 a b
3 a d
4 b c
#Reason for warning:
> x="Sepal.Width"
> strsplit(x,split=".")
[[1]]
[1] "" "" "" "" "" "" "" "" "" "" ""
> str_detect(x,".")
[1] TRUE
> str_replace(x,".","_")
[1] "_epal.Width"
> str_replace_all(x,".","_")
[1] "___________"
