Correlation between a numeric and factor in R

Question

I'm new to R and I'm trying to find the correlation between a numeric variable and a factor one. I have a data frame with the following 3 columns: 1. nr of clicks (range 0:14) 2. response (1= "YES", 0="NO") 3. Frequencies - no of counts (how many clients responded "YES" with X no of clicks)

So, the no of rows of the table is 28.

How can I measure the correlation between the dependent variable, response, and the numeric one?

Thanks! Rodica

In order to determine correlation between heterogeneous variables, you can use hetcor() function from the polycor R package: http://cran.r-project.org/web/packages/polycor.

Please keep in mind that the package seems to rely on factor orderings. The package does not seem to give sensible results for unordered variables. – Holger Brandl Jun 03 '19 at 11:44
