Try something like : > stdrange <- function(x) {(x-min(x))/(max(x)-min(x))} > var=1:10 # not a good idea, just for fun > stdrange(var) [1] 0.0000000 0.1111111 0.2222222 0.3333333 0.4444444 0.5555556 0.6666667 [8] 0.7777778 0.8888889 1.0000000 > Thank you in advance. > > > Sergio Della Franca > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@stat.math.ethz.ch 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. > > > -- Stéphane DRAY ([EMAIL PROTECTED] ) Laboratoire BBE-CNRS-UMR-5558, Univ.
