If the numbers are to be uniformly distributed within the range you specify, see ?runif: > runif(10, 0, 0.5) [1] 0.33273548 0.34751295 0.15387123 0.32831769 0.01863003 0.28881336 [7] 0.25578130 0.47281504 0.29631693 0.21392932 > runif(10, 0, 0.7) [1] 0.52535461 0.12373738 0.40943192 0.02131712 0.32761085 0.22612708 [7] 0.40411518 0.33841189 0.02760388 0.03942751 This would be covered, for example, in An Introduction to R: http://cran.r-project.org/doc/manuals/R-intro.html#Probability-distributions HTH, Marc Schwartz ______________________________________________ [email protected] 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.
