[R] How to write the output of a function into a file?

[Gavin Simpson]

does sink()

do what you want?

see ?sink for more

> #divert printed results to file
> sink(file = output.txt)
> #commands here
> chisq.test(x,p=probs)
> #turn off sink
> sink(file = NULL)

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

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.
