Hi there, I've been trying to use fitdistr fuction to fit our data onto a gamma distribution, sometimes it works and sometimes it doesn't. I realized that our data 10% of time is normal distributed instead of gamma. Since this is included in a processing pipeline, I'd like to test the fitting to see which fitting is better. Is there any way of doing this? Thanks very much! David

...on, that includes several functions inside. To avoid that everything stops if there is an error, I have this statement bla = function(....){ ... if(exists("last.warning")){rm(last.warning)} ... } inside the function, which if I use it normally, it works fine, but once I use it with the funciotn it gives me an error like: $"remove: variable "last.warning" was not found" NULL which breaks my function. I just want to make it do: if exists the file last warning, remove it, if not, just proceed... Does anyone knows why this happens? How can I avoid it? Thanks in advance....

Dear R-helper, I would like to compare the AUC of two logistic regression models (same population). Is it possible with R ? Thank you Roman Rouzier [[alternative HTML version deleted]]
