I found out something strange when I used the same thing on another data file.
In a excel file I have same data too and there I asked in a certain column what values where above the 7.5. Result: 206. Now I have done the same thing in R and I get as result: 400. My code: # Find values above 7.5. C = x[x => 7.5] # Calculate length. number = length[C] # print outcome number Or could it have something to do that I have calculated the log2 value from a value dat was like: 7.84394 -01 However I don't think that was the problem since I cheaked the first 10 log2 values, and they where correct. I just don't understand why the answer is now higer, 400 and not 206..... -- View this message in context: http://r.789695.n4.nabble.com/Sort-out-number-on-value-tp4573467p4573764.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.
