Dear all i use R only a few days and don't understand the difference between fivenum(x) und summary(x).
> x [1] 20.77 22.56 22.71 22.99 26.39 27.08 27.32 27.33 27.57 27.81 28.69 29.36 [13] 30.25 31.89 32.88 33.23 33.28 33.40 33.52 33.83 33.95 34.82 > fivenum(x) [1] 20.770 27.080 29.025 33.280 34.820 > summary(x) Min. 1st Qu. Median Mean 3rd Qu. Max. 20.77 27.14 29.03 29.17 33.27 34.82 And why is the 1st Qu. 27.14 although qL=x(1/4*(n+1))=x(23/4)=x(5 3/4) x(5)=26.39 x(6)=27.08 why is ql in summary between x(6) und x(7)?? I have learned that 1st Qu. = q(0.25)... so i am a little confused. Thanks a lot Matze ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
