Removing all binary variables from the data

Question

I have data as follows:

df <- data.frame(A=c(1,2,3), B=c(1,0,1), C=c(0.1, 0.011, 0.3), D=c(0, 0.5, 1))

  A B     C   D
1 1 1 0.100 0.0
2 2 0 0.011 0.5
3 3 1 0.300 1.0

Ho can I remove all binary variables (= B) from this data.frame?

Answer 1

You can use this:

Filter(function(x) !all(x %in% c(0, 1)), df)

Output:

  A     C   D
1 1 0.100 0.0
2 2 0.011 0.5
3 3 0.300 1.0

Note: you could also add NA to c(0, 1) if needed.
