R help - Mar 2003 - How to write the output of a function into a file?

I cannot find the solutions in the mannual about "import and export of
data".
For example, I run 
>chisq.test(x,p=probs)
    chi-squared.....

.........

How can I write the output into a file? Is there some file operations in R?
Actually, I only want to save the P-value. But I don''t know how I can
extract the P-value field only from the output
of chisq.test. So, I think I would better save all the output. I tried
cat/write....They cannot do this.

Thanks in advance.

Take a look at 
 ?write
 ?save

It is very clearly documented in ?chisq.test (to get only the p-value).

does sink()

do what you want?

see ?sink for more

If you are not typing the commands at the prompt but are using an external
editor or text file for your commands via source() then you need to wrap
chisq.test(x,p=probs) in print() eg:

print(chisq.test(x,p=probs))

Hope this helps
