[R] Echo in sink? Was: dumping the summary of lm to a text file

[Spencer Graves]

NEW QUESTION:  Is it possible to get the commands echoed in a sink file? 

ANSWER TO ADRIAN: 

      Have you considered "sink"?  This captures print results but not 
the commands that generated the print.  For example, consider the 
following: 

 > sink("tst.txt")
 > a <- 1
 > a
 > sink()

      The resulting file "tst.txt" contains only the one line obtained 
from "a", which is the same as "print(a)": 

[1] 1

      Similarly, it looks to me like the following 3 commands will 
produce what you want: 

sink("tst.txt")
sreg
sink()

      hope this helps.
