Hi Bert, I read both options and write.table help, but I still can't make it to save the data into txt file with fixed precision.
To let you know more clearly what I want, I still you use the previous simple example to illustrate. I want to save pi into pi.txt file with 10 decimal places, that is 3.1415926536. How to do it?
