Writing a file to the disk

I am having difficulty writing the code for the following operation: I have a numeric vector pred_out of length 156. (N = 156). Under Windows XP, I need to write it to the disk in text format. Perhaps some kind soul would provide the code fragment. The file name is sheet_vec.txt. Please see [1] for the complete pathname. Each number to be written out has the following format: LL.RRRRRR where LL is the integral part and RRRRRR is the fractional part to six decimal places. Example: "10.226207" The integral part, LL, is a maximum of two digits long. All numbers are positive. Another hypothetical example: 10.226207 6.556988 4.395678 etc. Each number is to be on a separate line. Please correct me if I am wrong: A \n (newline) character ends each line. After writing the file, it can be closed but not destroyed. (What I plan to do next is copy and paste the pred_out data into a spreadsheet.) Compressed formats (zip, etc.) should be avoided if possible. Your ideas? Tom Jones [1] The full Windows pathname is: C:/Documents and Settings/Tom/My Documents/Election Day Study Nov 7, 06/

Sorry, but the pathname is too long to fit on one line.
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)
writeLines(text, file.choose())
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
spreadsheet.
