R help - Apr 2010 - numerical or not?

Hi,
I've had a little problem for several weeks now. It is annoying and  
therefore I will ask for help now:
When I write a script with several iterations, I make it write out a  
text file to save the data during the run. For example I write:
if (i %% 25) write.table(output,"temporary_output.txt")
Later on, when I read in this output and want to calculate things, R  
complains that x is not numeric.
I read it in with the following command:
dat1<-read.table("temporary_output.txt",header=TRUE).
It seems that R is saving my temporary output as a list.
What is here wrong? And how can I do it better?

Thanks.

If you are saving it to read back into R, then consider using 'save' and
'load'.  It will avoid any problems that you might have when converting
back
and forth from the internal format to ascii data in a flat file.

Also since you posted no data, there is no way we can help you solve the
problem.

This time I attached the temporary_output.txt:
