Hi R lovers

Here is a numerical vector test

Assuming it follows a lognormal distribution I'd like to determine the mean
and the sd thanks to maximum likelihood estimation

> fitdistr(test,"lognormal",start=list(200,10))
Error in print.fitdistr(structure(list(estimate = c(4.54666263736726,  :
        more elements supplied than there are to replace

I chose the parameter start randomly

I don't understand the error message. Has anybody ever encountered such
one?
thanks for the help

have a wonderful day
