...n coss simulation, of say 200 coin tosses. The idea is to have a data frame like so: Experiment# Number_Of_Heads 1 104 2 96 3 101 So I do: d <-data.frame(exp_num=c(1,2,3)); /* Just 3 experiments to begin with */ d$head_ct <-sum(sample(0:1,200,repl=TRUE)); d; exp_num head_ct 1 1 85 2 2 85 3 3 85 /* the same scalar value is applied to all the rows */ So I tried using "within", and "for", and making the "sum( "...
