hello, my question concerns how to get variables from hist function? pp is some variable>hist(pp) #gives the histogram of pp >str(hist(pp)) #gives 4 variables which values are for example$breaks : num[1..18] 5 10 15 20 25 ... $counts : int[1..17] 1215 19381 47721 ... $ intensities : num [1..17] 0.00243 0.03876 0.09544 ... $mids : num[1..17] 7.5 12.5 17.5 22.5 ... I want to plot intensities against mids for example what I need is to get intensities and mids as variables to be able to use plot function. thank you for help -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
