Re: [R] MDA

Hi Tjun, It sounds like you need to go on an NA hunt (e.g: find your missing values in the data). Maybe try running this code: ss - which(apply(is.na(forsen[,-f]), 1, sum)0) forsen[ss,-f] And try to see if you can find these rows. You can also use the above data to find which rows to remove

[R] MDA

I am trying to use the package mda And this is my command mdfit-mda(factor(forsen[,f]) ~ .,data=forsen[,-f],subclasses=sc) But I keep getting this error message on a particular data set Error in maxdist[l] - x[l, i] : NAs are not allowed in subscripted assignments Can anyone help ? Thanks
