Hi everybody,
i'm trying to draw rarefaction curves to estimate a population size from
genotyped faeces.
I used the Gimlet software which gave me a script and a "rarefaction.txt"
file. I've copied both files in the work directory of R.
I changed library(nls) by library(stats) in the script.
But now, i'm still unable to run it.
If i ask to show error messages, the software gives me after the last line :
"Read 36 items
Erreur dans return(echa, faesel) : 
  les renvois multi-arguments sont inderdits".

Does anybody know where i made a mistake?
Thanks a lot,
