Closed:how to use the pegas package to calculate tajima D

Question

[mimi]

Hello,

I try to use the package pegas of R for calculate the Dtajima, but I have a problem :

[data(Myexample)
Warning message:
In data(Myexample) : data set Myexample not found]

I used the tajima test : with a function "read.fasta"

require(ape)
data(Myexample)
tajima.test(Myexample)

My data is an alignment of 100 bacteria genoms.

In your opinion why it does not recognize my data ?

Thank you
