Exporting in XPS

Dear all,

before applying any filter to Exon data, I would like to export them to a text file as transcripts, i.e, I have
RMAed my data using the following command following the code coming along with the package:

rma.tc.core <- rma(data.exon, "MixExonRMAcore", filedir=outdir, tmpdir="",
background="antigenomic", normalize=TRUE, option="transcript", exonlevel="affx+core")

Is there a way to get an output like the following (also non log2 trasformed data will suffice):

GeneID  HCC1187 SUM44PE MCF7    MDAMB436        LY2     BT549
A1BG    6.31    6.35    6.66    6.47    6.81    6.66
A2M     4.37    4.58    4.57    4.44    4.84    4.47
A2ML1   5.50    5.85    5.54    5.53    5.60    5.31
A3GALT2 6.13    6.10    6.06    6.23    5.99    5.76

Thanks in advance.

Giovanni
