Error while imputation of the missing values

Hello everybody,

I get the following error while trying to impute the missing values:

Create objects for storing processed data

mSet<-InitDataObjects(“pktable”, “mf”, FALSE)
mSet<-SetDesignType(mSet, “multi”)

Loading the data table and the metadata

mSet<-Read.TextDataTs(mSet, “C:/Users/xxx”);
mSet<-ReadMetaData(mSet, “C:/Users/xxx”)

Replacing missing values

mSet ← ImputeVar(mSet, method=“knn”)

Error: Error in t.default(int.mat) : argument is not a matrix

I would be grateful for help how to solve it!

Already solved, thanks!
