I have a dataframe with many observations and many variables. Some of them are categorical (unordered) and the others are numerical.
I'm looking for associations between these variables. I've been able to compute correlation for numerical variables (Spearman's correlation) but :
- I don't know how to measure correlation between unordered categorical variables.
- I don't know how to measure correlation between unordered categorical variables and numerical variables.
Does anyone know how this could be done? If so, are there R functions implementing these methods?
