Log y-axis on histograms are conceptually wrong, but aren't a bad idea either. It is conceptually safer to show this using "density". Consider an exponential distribution, which could look better with a log y-axis:
x <- rexp(10000,.1) xd <- density(x,from=0) par(mfrow=c(2,1)) plot(xd) plot(xd,log="y",ylab="Log Density") Just use caution in the interpretation. The large dropping/osculating features on the right-hand side of the log plot are from sparse data-points, and this can be smoothed out by adjusting 'bw' to get a "theoretical" interpretation of the true distribution. +mt ______________________________________________ [email protected] 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.
