[R] is there a way to call python like source(file, echo = TRUE) in R?

[Yihui Xie]

Sorry this is more like a Python question, but I believe many R users
also know well about Python, so here is my question: I want to run
python code like source(file, echo = TRUE) in R, i.e. echo both the
source code and the output.

This only shows the output:

python -c 'print "hello"'

Thanks!

Regards,
Yihui
