Histograms with bin proportions on the y-axis
To open a graphics device, you usually use a function like png() or eps() then do your plotting then dev.off() to close it when you're done. Sounds like you need something like hist(x, breaks = 100, freq = TRUE) Hope that helps, Michael On Sun, May 20, 2012 at 3:07 PM, Nick Gayeski

I have what is probably a simple problem. I have a data file from an MCMC Bayes estimation problem that is a vector of 500,000 numeric values (just one variable) ranging from 100,000 to 700,000. I need to display the histogram of this data in a high quality graphic for a figure in a journal publication. I want 100 bins so as to display a reasonable complete and smooth histogram, and I need the Y-axis to display the bin proportions. I'm new to all of the graphics capabilities of R. Can anyone provide me with the command I need to issue to the call to hist to get the output that I desire? ?I assume that once I have the desired histogram I will be able to save it in a format like .eps that will permit it to be reproduced in high resolution. But any suggestions for this task would also be appreciated. Regards, Nick ? ? ? ?[[alternative HTML version deleted]]
