Hi Xavier,
I use the fitdistrplus and logspline packages to know which distribution fits better my data.
Here is an example :
install.packages("fitdistrplus")
library(fitdistrplus)
instal.packages("logspline")
library(logspline)
x=c(44986,18288,56147,44488,41018,40631,27301,39025,45688,47172,12300,21558,16103,48874,67245,36119,10398,42630,12879,34058,84443,30639)
descdist(x,discrete=FALSE)
Cheers,
S.
