R help - Feb 2004 - Puzzled by write.table function

I am puzzled by the following:

I use two write.table function(write into files)  in my code  as following
(I use  source to call the code): 
....
write.table (x1, file ="x1.txt", quote = "FALSE",
append=FALSE, sep="\t",
eol="\n", "na=NA"...)
....(more statement)
..
write.table (x2, file="x2.txt"...)


 it turned out the second one is always empty. 

I know there is nothing the code itself as I can get second write.table
statement work if I comment the first.

Does anybody know what happened here?

Thanks.

No, in particular not in this case, because you have given a 
non-reproducible example (moreover, it is syntactically wrong!).

Please also tell us your version of R and your OS.

Hi,
Sorry,the syntax in the email was wrong. 


The code is boring, it virtually processes some data and write the results
out using write.table function at the end. The output has <10,000 rows.

Here is part of the code:

....

write.table(sigGene, file="sigGene1.tab",append=FALSE, quote = FALSE,
sep
="\t", eol = "\n", na = "NA", dec = ".",
row.names =FALSE, col.names=FALSE);

write.table(cbind(gene,geneScored),
file="sigGene_scored.tab",append=FALSE,
quote = FALSE, sep="\t", eol = "\n", na = "NA",
dec = ".", row.names
=FALSE,col.names=FALSE);

sigGene is a matrix of 2 cols, gene, geneScored  are vectors generated by
early code.


I used the linux version 1.7.1.


Thanks
