impCoda with method=classical error: 'list' object cannot be coerced to type 'double' error

Hello,

Thank you for developing such a useful R package for Compositional Data Analysis.I've discovered that if I run impCoda with method='classical', I get the following error: "Error in is.data.frame(x) : 'list' object cannot be coerced to type 'double' ".

Here is my SessionInfo and some sample code that generates the error. I'm using the latest version of robCompositions from CRAN.
