I figured out something new that I would like to see if I can do this more easy with R then Excel.
I have these huge files with data. For example: DataFile.csv ID Name log2 1 Fantasy 5.651 2 New 7.60518 3 Finding 8.9532 4 Looeka -0.248652 5 Vani 0.3548 With like header1: ID, header 2: Name, header 3: log2 Now I need to get the $ID out who have a &log2 value higher then 7. I know ho to grab the $log2 values with 7+ numbers. Log2HigherSeven = DataFile$log2 [ DataFile$log2 >= 7] But how can I take thise ID numbers also? -- View this message in context: http://r.789695.n4.nabble.com/How-to-take-ID-of-number-7-tp4577998p4577998.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.
