List of metrics not allowed if X is a matrix.

List of metrics not allowed if X is a matrix.

I tried the option metric=list("cosine"=1:27, "categorical"=28) on my data (matrix with dimnames) and got this error:

Error in match.arg(metric, c("euclidean", "cosine", "manhattan", "hamming", : 'arg' should be one of “euclidean”, “cosine”, “manhattan”, “hamming”, “precomputed”

If I set X=as.data.frame(mydata) the error is gone.

Thanks.

Maybe this line:

Could be:
if (methods::is(X, "data.frame") || methods::is(X, "matrix")) {

Thanks for the report. I have added the fix to master.

To be on the safe side, I would always recommend converting X to a data frame and explicitly converting any column you want to be treated as categorical to a factor.

Pretty sure this is fixed. Please re-open if not.
