Thanks for your help, Phillipe. You're right; I don't need to use sink() function. I was using R for windows in an interactive mode and have totally forgotten about batch mode. For others' reference I opened up a command prompt and typed in: Rterm --no-save --quiet <test.R >test.log and created test.log gave me the results I wanted. Cheers, SI -----------------

I am using many comment lines like this # a comment line in a script. Is there any way to print comment lines when I use sink() function? Or, are there any plans to include as an option to sink() function in the near future? I would not want to use cat() function as it will look messy in the original script file.
Since you are using script files, you may not need to use R in an interactive session. One suggestion under unix would be: cunegonde:~> R --no-save --quiet < test > saved cunegonde:~> cat saved
# a comment line i<-1:10 outer(i,i,"*")
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,] 1 2 3 4 5 6 7 8 9 10 [2,] 2 4 6 8 10 12 14 16 18 20 [3,] 3 6 9 12 15 18 21 24 27 30 [4,] 4 8 12 16 20 24 28 32 36 40 [5,] 5 10 15 20 25 30 35 40 45 50 [6,] 6 12 18 24 30 36 42 48 54 60 [7,] 7 14 21 28 35 42 49 56 63 70 [8,] 8 16 24 32 40 48 56 64 72 80 [9,] 9 18 27 36 45 54 63 72 81 90 [10,] 10 20 30 40 50 60 70 80 90 100
# the end
