Hi All, i) I wanted a plot with a x axis that ranges from 25 to 75 points and 2 normal curves on it with y-axis suppressed.
ii) One with mean 60 and standard error 2 and the other one with mean 40 and standard error 5. iii) At last, I'd like you to pull some random values from those distributions and superimpose them, e.g. the numbers 1, 2, 3, ... 10 as symbols superimposed on top of the normal curves. I have no idea how do to the last part (iii). Any help is appreciated. This is what I did for the first two parts. ###### x <- seq(25,75) y1 <- dnorm(x,40,5) plot(x,y1,type="l", lwd=2, col="blue",yaxt="n",ylim=c(0,0.18),ylab="",xlab="two veru different populations") y2 <- dnorm(x,60,2) lines(x,y2,type="l", lwd=2, col="red",yaxt="n", ylim=c(0,0.18)) ##### Thanks, -Debs ______________________________________________ R-help@r-project.org 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.
