[R] Incomplete ouput with sink and split=TRUE

[Alex Brown]

you could use the unix function 'script' before invoking the R  
interpreter.

example session:

$ script
Script started, file is typescript
[x86_64|alex at riki:~]
$ R --quiet --vanilla
 > 1:10
[1]  1  2  3  4  5  6  7  8  9 10
 > q()
[x86_64|alex at riki:~]
$ exit
exit
Script done, file is typescript


contents of file typescript:

===========
Script started on Tue Feb  5 19:01:32 2008
[x86_64|alex at riki:~]
$ R --quiet --vanilla
 > 1:10
[1]  1  2  3  4  5  6  7  8  9 10
 > q()
[x86_64|alex at riki:~]
$ exit
exit

Script done on Tue Feb  5 19:01:45 2008
[x86_64|alex at riki:~]
