[R] Beginner help about output in R

[nicolapon]

Dear R experts,

I am a beginner with R and I have a question regarding the output of a
function.

Basically, I created 2 functions, value1 and value2, that calculate two
values, and I would like to print those two values to an output datafile. I
tryed the following function:

function (x) {write.table(data.frame(value1(x),value2(x)),file=output.txt)}

My problem is that I would like to calculate those values for different
values of x and to get one line in the output file per value.
When I use this function for the second time, it erases the value of the
first try, etc. How can I proceed so that I will add a new line to the
output at every step instead of deleting the previous line?

Thank you very much for your answers!

Nicolas
