Say I have a list: [[1]] "I like google" [[2]] "Hi Google google" [[3]] "what's up"
and they are tweets. And I want to find out how many tweets mention google (the answer should be 2). If I string split and unlist them, then I would get the answer of 3. How do I make sure I get just 2? -- View this message in context: http://r.789695.n4.nabble.com/matching-strings-in-a-list-tp4709967.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
