Your email address says otherwise, so you should expect some confusion.

Please send the code that shows that the Sus scrofa genome is not
represented in biomaRt.  That will involve using the useMart() and
listDatasets() functions.  After you show that code and the result, we can
have a better discussion.  However, I think you might be surprised by the
results you obtain.

i can use it very well, but it cannot solve my problem.

We do not assume that you either do or do not know how to use the biomaRt
package.  We do SUGGEST STRONGLY, however, that when one of us suggests
that you try something that you ACTUALLY DO IT.  If, for some reason it
does not work for you, show why it did not work or what, specifically, you
did not understand.  Also, we assume that you have read the relevant
documentation carefully (every function or method that you use) and the
onus is on you to show that you have.

I answered your question quite clearly, I believe.  I did not do your work
for you, though.  There is a difference.  Please do not take my remark here
to be anything other than constructive.

The purpose of the email list is NOT simply to have users simply share
convenient code, although it sometimes serves that purpose.  The email list
is to help users HELP THEMSELVES to solve their specific problems; my
writing code for you will help you in the short run, but not always in the
long run.  Also, keep in mind that all of us are busy people, so please do
not expect worked code examples to be posted to the list, especially when
the example in the documentation answers the question.

Again, I hope you take both Nico and my comments in the most constructive
way possible.  All of us were in your shoes at one point and know that
learning Bioconductor can be challenging.
