[BioC] Writing table from DGEExact object (edgeR)

[Karen Sherwood]

Dear All,

I would appreciate some help with writing a table out from a DGEExact
object. I have used edgeR to produce an DGEExact output table. The data
frame contains the log-concentration (i.e. expression level), the log-fold
change in expression between the two groups/conditions and the p-value for
differential expression as columns and many several thousand rows (from
high-throughput sequencing data).  I would like to know how to write.table
this object. 
If I write.table (object name,"file.txt",sep-"\t",col.names=NA), the error
is returned

Error in data.frame(table=list(logConc=c(),: arguments imply differing
number of rows:18314,2,0

I have tried sink, write.csv and write.foreign from package foreign but I am
unable to write the object out. 

Any suggestions would be greatfully received,
Thank you,
karen
