Hi all, How does R know to regard a variable as a factor and not a character? For example, consider the following table:
Observation Gender Dosage Alertness 1 m a 8 2 m a 12 3 m a 13 4 m a 12 5 m b 6 6 m b 7 When read into a dataframe, will "m", "a", "b" be regarded as a factor or as a character? How does R decide? Thanks a lot in advance, Asaf -- View this message in context: http://r.789695.n4.nabble.com/Data-type-in-a-data-frame-tp4647161.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
