I'm sorry. I do appreciate you are trying to help. However, what I am trying to
do is not exactly the same as in FAQ.
If I do the following:
test2=list(numeric(0),c(10,20));
test1=list(c(1),c(1,2,3,4));
for (i in 1:2){
tryCatch(wilcox.test(test1[[i]],test2[[i]]),error = function(e) NULL);
}
I cannot get the p-value of the test for i=2.
any other input? anyone?
Thanks,
Lin

As a matter of fact, I did read the FAQ. However, in the FAQ coef() is used to
return the coefficients of lm() if it succeeded.
I cannot find similar function for pvalue.
So your question has nothing to do with the subject line? If you are trying to
get information about the object returned by the wilcox.test function, then
you should be looking at the help page in the Value section for that function.
