Percent damage distribution
R version: 2.7.0 Running on: WinXP I am trying to model damage from fire losses (given that the loss occurred). Since I have the individual insured amounts, rather than sampling dollar damage from a continuous distribution ranging from 0 to infinity, I want to sample from a percent damage distribution from 0-100%. One obvious solution is to use runif(n, min=0, max=1), but this does not seem to be

Adding x-axis values to a histogram
Dear useRs, Is there a way one can add x-axis values to a histogram? Example: z = rgamma(n=1000, shape = 8, scale = 1000) hist(z, breaks = 30) Currently I see 4 x-axis values: 5000, 10000, 15000, 20000. Can I add more values or modify the ones currently showing?

Same initial seed
Hello, I have tried a few searches without luck before posting, since this one seems a pretty basic question. I am using R 2.7.0 on WinXP, as I have long started using this version for my thesis work and am reluctant to update fearing consistency/backward compatibility issues could happen. I noticed that whenever I start an R session (launch the console application) and run a script involving
