R Read.table 一列有多个词

Question

我有一个这种类型的日志文件要在 R 中处理：

2015-11-23 11:51:02,082  INFO      FrameworkApplication - ****** Start entimICE Application Command Line Parameters ******
2015-11-23 11:51:02,082  INFO      FrameworkApplication - ****** Config-File: E:/Program Files (x86)/conf/storages.dsconfig
2015-11-23 11:51:02,082  INFO      FrameworkApplication - ****** Datasource: datasource
2015-11-23 11:51:02,082  INFO      FrameworkApplication - ****** Application: App
2015-11-23 11:51:02,082  INFO      FrameworkApplication - ****** Ignore : false
2015-11-23 11:51:02,082  INFO      FrameworkApplication - ****** Plugin: com.plug
2015-11-23 11:51:02,082  INFO      FrameworkApplication - ****** Logging: E:/Program Files (x86)/conf/log4j.properties
2015-11-23 11:51:02,082  INFO      FrameworkApplication - ****** End Application Command Line Parameters ******
2015-11-23 11:51:02,129  INFO               BaseRuntime - Runtime created in mode: RichClient

我试图将它放在一个数据框中，并读取 table，但它把我的每个单词都放在一列中，我想要一个包含 5 列的数据框：

date        time           type  element              text
2015-11-23  11:25::02,082  info  FrameworkAplication  - ****** Start entimICE Application Command Line Parameters ******

问题是我的字段分隔符是 space 以及我不希望在不同字段中使用的单词分隔符

是否可以通过 read.table 或扫描，或者我应该执行我自己的功能？

谢谢，

@ma33kael 你有没有试过一式两份的解决方案？因为它按预期工作

library(readr)
a <- read_fwf(text, fwf_widths(c(10,13,6,1)))

给你：
