I'd like some help with an issue that might seem easy but I'm stuck in my analysis. 

I'm working with R on a dataframe containing 15 variables: 14 numerical or Integer and 1 factor. I'd like to do some clustering on my dataframe but here is the issue: 

Usually, when I'm working with factor variables for clustering, I do a MCA analysis and keep the coordinates as numerical variables on which I do my clustering (usually kmeans). 

The thing is that I don't really have any idea on how I can work with this only factor factor variable.

Should I use dummies? 
Any other idea?
