R help - Mar 2012 - histogram break width

Hi all,

I am generating histograms with the following R script :

#!/usr/bin/Rscript

out_file = "histo.png"
png(out_file)

scan("values.csv") -> myvalues
hist(myvalues, breaks = 50)

dev.off()

print(paste("Plot was saved in:", getwd()))


I want the histogram to have a larger number of breaks, but a smaller
break width, the idea is to make it appear smoother like a filled
curve. If I keep increasing breaks it starts looking messy. Any
suggestions?

Thanks!

Get better data?
Use a different type of plot, like a filled curve maybe?

If a histogram isn't meeting your needs, then use something else.
