R help - Apr 2010 - Non-parametric Tests for location in R

How do I do the sign test and the sign rank test that SAS gives as an output
in proc univariate in R?

sign.test
and
wilcox.test

do not give the same output.

Also how do you pick what output you want displayed in R?
like if I want only the test statistic and p value displayed and nothing
else how do I do that.

Thanks.

No data, no specifics, no code. Rather difficult to determine whether  
you made an error or  .... what?

Most such functions return lists. One can look at the names of the  
components of such lists with str and extract the desired components.  
In the case of wilcox.test you do not need str because you can just go  
to the Value section of the help page and it's all laid out for you  
(as it should be.) You could assign the results to say, wres, and then :

wres$statistic
wres$p.value
