[BioC] using write.table on exprSet objects

[Laurent Gautier]

  Hi,


  Here is a question I have been asked by email, but I tought it could be of help to others.

  The question was 'write.table(my.exprset) gives an error message. How can I save the expression
values I generated with the function express() in a tab separated file ?'. 

  The answer was:
- exprSet objects contain different attributes. Try class?exprSet  to know more.
- Assuming you are interested in the expression values, try
write.table(exprs(my.exprset), file="mydata.txt", sep="\t")



  Hopin' it helps,



  Laurent
