Hi,
I want to make factor analysis in RPy. In R is easy, all factor analysis
methods want numeric data and my data consists of categorical variables so
I make them numeric with as.numeric.
Method as.numeric works on factors (factors are R cathegorical variables).
But when I read data in RPy I only get list of strings instead of factors.
How can I turn these lists of strings (e.g. ['brave', 'non.brave',
'non.brave', 'brave', 'brave', 'brave',]) into numerical lists that will be
appropriate for factor analysis?
I would appreciate any ideas.
