我正在学习 R 进行文本挖掘。我有一个 CSV 格式的电视节目时间表。节目通常从早上 06:00 开始,一直持续到第二天早上 05:00,这被称为广播日。例如:15/11/2015 的节目从早上 06:00 开始,到第二天早上 05:00 结束。
这是一个示例代码,显示了日程安排的样子:
read.table(textConnection("Sunday|\n 01-Nov-15|\n 6|Tom\n some information about the program|\n 23.3|Jerry\n some information about the program|\n 5|Avatar\n some information about the program|\nMonday|\n 02-Nov-15|\n 6|Tom\n some information about the program|\n 23.3|Jerry\n some information about the program|\n 5|Avatar\n some information about the program|"), header = F, sep = "|", stringsAsFactors = F)
