How can I suppress the output to console when importing packages in RPy2 in Python?

Question

Whenever I run a script importing packages with import in RPy2 in Python, there are always some extra lines popping up in the console. I pasted in an example below. How can I suppress that behavior?

CookieJar:r cookies$ python script.py 

    ‘tseries’ version: 0.10-24

    ‘tseries’ is a package for time series analysis and computational
    finance.

    See ‘library(help="tseries")’ for details.

Answer 1

Besides require(tseries, quietly = TRUE) and using sink() , or its Python equivalent, there is also the simple

suppressMessages( library( tseries ))

which I prefer.

Answer 2

You could temporarily redirect the output stream to a blackhole just before the spammy peice of code.

import sys

class Blackhole(object):

    def write(self, string):
        pass

stdout = sys.stdout
sys.stdout = Blackhole()

function_el_spammo()

sys.stdout = stdout

Answer 3

在你的R脚本中，我会预加载tseries包（以防万一，如果它被其他一些函数/包调用）使用

require(tseries, quietly = TRUE)
