Hi Dennis, you could get the result using 2 approachs: 1) a <- c(1,1,1,1,2,3,4,5,5) b <- table(a) > print (b[1]) 1 4 Now, print (b[[1]]) > 4
> rownames(b) [1] "1" "2" "3" "4" "5" c =rownames(b) print(c[1]) 1 2) > b= tabulate(a) > b [1] 4 1 1 1 2 > print(b[1]) [1] 4 Emir Toktar > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of dennis11 > Sent: Tuesday, August 12, 2008 5:21 AM > To: r-help@r-project.org > Subject: [R] Frequency vector > > > I want to create a vecor with frequencies. > > I have tried this: > > a <- c(1,1,1,1,2,3,4,5,5) > b <- table(a) > print (b[1]) > > which results in: > > print (b[1]) > 1 > 4 > > The only thing I want is the 4. > > So this seems obvious: > print (b[1,2]) > > but it does not work: > Error in b[1, 2] : incorrect number of dimensions > > How do I get a vector or how do I refer to the "4" without > getting the "1" > label as well? > -- > View this message in context: > http://www.nabble.com/Frequency-vector-tp18939882p18939882.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. ______________________________________________ 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.
