我使用read.table导入R中的数据，代码如下：
txt=read.table("C:\\Work\\Network Monitoring\\Text mining syslog\\small set.txt", sep="\t", col.names=c("message", "device"))
在txt文件中，每个数据行都是：
%SPANTREE-SP-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan id 1 on GigabitEthernet6/21 VLAN49. sn1-65ag-hot-137b
如果第一个元素是消息而第二个元素是设备，则这两个元素由制表符分隔。
我收到此错误消息： 扫描错误（文件，内容，nmax，sep，dec，quote，skip，nlines，na.strings，： 第15行没有2个元素
但是我使用编辑板专业版来检查正则表达式，并在消息元素和设备元素之间看到第15行中唯一的一个选项卡。
有人可以帮忙解决这个问题吗？
非常感谢你们所有的投入！
所以我在read.table命令中添加了fill = TRUE，这是
txt=read.table("C:\\Work\\Network Monitoring\\Text mining syslog\\03_28_2MB.txt",sep="\t",fill=TRUE, col.names=c("message","device"))
以下数据附有一个样本，总共40行。在read.table命令之后，有三条数据线正确读取，这三条数据线在下表中的第16,34,38行。 （对不起，在这个帖子中，粗体对我不起作用。）所以我发现所有三行都包含标签＃。我检查了正则表达式，标签周围没有标签＃。你知道我怎么能避免这个问题？
真的很感激！

答案 0 :(得分：0)
您可以考虑填写缺失的数据（ fill = TRUE ）：
txt=read.table("C:\\Work\\Network Monitoring\\Text mining syslog\\small set.txt", sep="\t", fill=TRUE, col.names=c("message", "device"))
或使用不同的分隔符（例如一词）：
txt=read.table("C:\\Work\\Network Monitoring\\Text mining syslog\\small set.txt", sep="\son\s", col.names=c("message", "device"))
答案 1 :(得分：0)
您可以使用read.delim，默认情况下sep = "\t"。
> txt <- "%SPANTREE-SP-2-RECV_PVID_ERR: Received BPDU with inconsistent peer
vlan id 1 on GigabitEthernet6/21 VLAN49. sn1-65ag-hot-137b"
> writeLines(txt, "smallSet.txt")
> read.delim("smallSet.txt", header = FALSE, col.names = c("message", "device"))
message
