Get the formatted numbers you want in a character vector, then use
writeLines to write it out. For example:
x <- rnorm(20)
text <- sprintf("%9.6f", x)
This will open a file selection directory where you can navigate to the
correct folder and enter the filename. Alternatively, you could put the
whole path to the file in place of file.choose(). As a third choice,
you could just use "clipboard"; on Windows, this will write the text
directly into the clipboard, and you can paste from there to your
