[R] Plot histogram and lognormal fit on the same time

[Eric Leroy]

Hi,

I would like to plot the histogram of data and fit it with a lognormal 
distribution.

The ideal, would be to superimpose the fit on the histogram and write 
the results of the fit on the figure.

Right now, I was able to plot the histogram and fit the density with a 
lognormal, but I can't combine all together.

Here is the code I wrote :

histdata <- hist(dataframe$data)

library(MASS)

fitdistr(histdata$density, "lognormal")

Can you help me ?

Best regards,
