source() vs attach()0
Hello,
After hours of googling I could not resolve the following (although it 
seems simple):
I would like to put subfunctions in a separate .R file that is then 
called with source() from inside several "main" functions. A crude

**** file subtest.R **********
subtest <- function() {
  foo <<- foo+1
  }
******************************
*** main
