Not sure where the problem is? Since you did not provide sample data, I took the iris data set and converted it to your structure:
x <- cbind( iris[5], iris[1:3] ) head( x ) Species Sepal.Length Sepal.Width Petal.Length 1 setosa 5.1 3.5 1.4 2 setosa 4.9 3.0 1.4 3 setosa 4.7 3.2 1.3 4 setosa 4.6 3.1 1.5 5 setosa 5.0 3.6 1.4 6 setosa 5.4 3.9 1.7 Does that look like your data? If so, xbin <- cbind( x[1], binarize( x[2:4] ) ) gives a result that should look just like what you want: head( xbin ) Species Sepal.Length Sepal.Width Petal.Length 1 setosa 1 0 0 2 setosa 1 0 0 3 setosa 1 0 0 4 setosa 1 0 0 5 setosa 1 0 0 6 setosa 1 0 0 Using xbin <- cbind( x$Species, binarize( x[-1] ) ) doesn't make a difference. Or did I not understand your problem well?
