Hi all, I have this figure:

How can I resolve this problem? I specifically want to use the dgamma function with the learned parameter (alpha,beta). That's why I don't use this command: > lines(density(x),add=T, col="red") - Gundala Viswanath Jakarta - Indonesia ______________________________________________ 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.
