Dear list,

I am having a set of human oligo ids (H200006022 H200002025 H300004703
H200000442 H200005719 H300018350) which I want to map to Ensembl or RefSeq.
I am sure R has a function to do that. I downloaded the {oligo} package and
tried to use the probeNames function. Although the factor of ologo ids is an
object (as the argument to probeNames should be) I retrieve the following
error:
 probeNames(significant_genes[,1])
Error in function (classes, fdef, mtable)  :
  unable to find an inherited method for function "probeNames", for
signature "factor"

where significant_genes is the factor with the oligo ids. Could anyone help
me with the format I should use in order to apply probeNames? Or if someone
has any other function in mind whcih can do the mapping I would be really
grateful to hear that.

Thank you all,
Eleni
