I actually don't know what you mean by this (my own ignorance probably). Do I have > to parse table's names() to fetch bin endpoints For equal-width bins you can use seq(min(x), max(x), by = (max(x) - min(x))/10) HTH, Ista to pass them to > p[distr-name] functions? i really don't want to input arguments to PDF > functions by hand (nor copy-and-paste way). > >> x.fr <- table(cut(x,10)) >> x.fr > > (0.0617,0.549] (0.549,1.04] (1.04,1.52] (1.52,2.01] (2.01,2.5] > 16 28 26 18 6 > (2.5,2.99] (2.99,3.48] (3.48,3.96] (3.96,4.45] (4.45,4.94] > 3 2 0 0 1 > >> names(x.fr) > [1] "(0.0617,0.549]" "(0.549,1.04]" "(1.04,1.52]" "(1.52,2.01]" > [5] "(2.01,2.5]" "(2.5,2.99]" "(2.99,3.48]" "(3.48,3.96]" > [9] "(3.96,4.45]" "(4.45,4.94]" > > > -- > > Andrei Zorine > > ______________________________________________ > 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. > -- Ista Zahn Graduate student University of Rochester Department of Clinical and Social Psychology http://yourpsyche.org ______________________________________________ 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.
