Understanding R plot margins

Came across this great VISUAL explanation of the differences between margins (mar) and outer margin (oma) regions. This is very helpful.

How to subset RPy2 dataframe

This example demonstrates how to create subsets of RPy2 data frames using single or multiple criteria. I also wanted to test if using Github Gist is a better way the display code snippets on this blog than using Bloggers formatting tools.

	# By single criteria
	subset_frame = dataframe.rx(dataframe.rx2('input_type').ro == 'VALUE', True)
	# By Multiple Criteria
	subset_frame = all_data_frame.rx((dataframe.rx2('input_type').ro == 'VALUE1').ro &
	(dataframe.rx2('data_type').ro == 'VALUE2'), True)
