我有一个包含多个分隔符的大型文本文件 - ＆＃34;：＆＃34;，＆＃34 ;;＆＃34;，＆＃34;，＆＃34;。所有行都以：2015开头。以下是一行示例：
：2015,01,04; 22,06,07,57：1587.0059,1582.1625,1577.2192,1571.9540,1561.7333,1546.7213,1531.9143,1517.3482：1587.2206,1582.2081,1577.1512,1572.1362,1561.2966,1547.7744,1533.1818,1516.6925： 1587.4020,1582.1017,1577.2475,1572.2528,1562.0818,1546.2844,1532.8708,1516.4988：1587.1609,1582.2521,1577.2482,1572.2127,1562.2775,1547.7381,1532.7753,1516.0095
我应该如何将此文件加载到R中？有些线条具有这种不规则性，即一条线上存在两条线。我怎么处理这个？

答案 0 :(得分：1)
您可以将文件读取为字符向量（取自here）：
fileName <- 'foo.txt'
s <- readChar(fileName, file.info(fileName)$size)
然后，您可以使用strsplit分隔行：
L <- strsplit(s,split='2015:')
并且对于每一行，再次使用strsplit来分隔记录
lapply(L,strsplit,split=',|;|:')
