R help - Apr 2011 - How to get the tuning parameter lamda in storey's qvalue package

Dear All,
In Storey's estimator of the proportion of true nulls, the estimator depends
on the tuning parameter lamda.
Suppose now that an estimator of this proportion has been obtained by the qvalue
package, what is the lamda that
corresponds to the estimate? How to get this lamda?
Thanks,
-Chee

Just load the package and type

qvalue

so you will see what the underlying R code is. You will find some parts 
of the code may be worth to be improved, hence time to contribute to the 
package.
